A heart attack can occur suddenly and be a deeply upsetting experience. Following the diagnosis, hospitalization is required, along with the delivery of a wealth of information from the healthcare team. Then comes the need to adopt new lifestyle habits to reduce the risk of recurrence and improve long-term quality of life.
Rethinking Recovery
In the past, people who had suffered a heart attack were labeled as “cardiac patients” and often led very restricted lives. Extended rest, avoidance of physical exertion, and even limiting social interaction were common practices, all in an effort to avoid placing strain on the heart.
Over time, however, an unexpected reality emerged. Some individuals who remained more active—or who were less strict in following the imposed rest recommendations—showed better recovery… and improved survival.
These findings transformed medical practices. Recovery is no longer based solely on rest, but instead takes a more dynamic approach. Gradual reintroduction of daily activities is now considered an essential part of healing, always within a safe and personalized framework.
Today, cardiac rehabilitation centers offer structured, comprehensive support and are increasingly available—even outside major urban areas. Some people even report feeling fitter after their heart attack than they did before.
A Holistic Approach to Recovery
Recovery involves more than just taking medication. It also includes:
- adopting healthier lifestyle habits,
- engaging in regular, adapted physical activity,
- receiving psychological and emotional support.
Several common concerns are often addressed during cardiac rehabilitation:
- how long the recovery will take,
- when to resume household tasks, work, and social activities,
- whether it’s safe to drive again,
- and questions related to sexual activity.
These topics deserve open, reassuring discussions with healthcare professionals—so that every person can regain not only their health, but also their confidence and independence.
Understanding to Live Better
Learning about your heart condition, understanding the purpose of each medication, and receiving practical advice can help restore a balanced and fulfilling life after a heart attack. Proper medical guidance and a proactive attitude are key to a successful recovery.
A Necessary Look Back
After a heart attack, events unfold so quickly that, for most people, the memories become a blur.
That’s completely normal. Between the pain, emotions, medications, and the hustle of the hospital setting, it’s hard to process everything in the moment.
Revisiting what happened helps make sense of the event, reconnect the dots, and bring clarity to a situation that may still feel surreal.
The incident
Calling 911
But first, it’s essential to remember what to do in case of doubt. If you experience intense chest pain—especially if it’s accompanied by heavy sweating, nausea, or vomiting—call 911 immediately.
First Responders
Paramedics are often able to recognize a heart attack as soon as they arrive. Using specialized tools, they can begin treatment right away.
Even though they may explain what’s happening, the stress, pain, and sometimes sedation make it hard to fully understand the situation. That’s why people often have only vague memories of this part of the emergency.
Back to Basics: What Is a Heart Attack?
A heart attack—or myocardial infarction—occurs when a clot blocks one of the heart’s arteries. BloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood flow is interrupted, and the heart muscle served by that artery is deprived of oxygen.
This lack of oxygen causes pain and may lead to complications such as arrhythmias, heart failure, or valve issues. That’s why rapid intervention is critical.
Care Depending on Location
In urban hospitals, patients are quickly taken to a specialized unit where the blocked artery can be reopened. The sooner this is done, the less lasting damage the heart will sustain.
In rural areas, the approach may differ. Patients are first brought to the nearest hospital, where medication is administered to dissolve the clot. If this treatment isn’t effective, a transfer to a specialized center is then arranged.

The changes to be made
Lifestyle Habits
Fortunately, it’s well established that lasting lifestyle changes can have a major impact on heart health.
Eating better, exercising regularly, managing stress, and getting quality sleep can all help improve quality of life and reduce the risk of another heart attack.
Medication
After a heart attack, several new medications are often prescribed during hospitalization. While the idea of taking multiple pills may seem overwhelming at first, these treatments are essential for supporting heart function and preventing further events.
It is crucial to follow the prescribed dosages closely and never stop a treatment without first consulting a healthcare professional who knows your medical history.
A dedicated section is available here to help you better understand how heart medications work, their benefits, and potential side effects:
See the section: Pharmacy
The most common medication classes include:
- antiplatelet agents,
- beta-blockers,
- ACE inhibitors (angiotensin-converting enzyme inhibitors),
- ARBs (angiotensin II receptor blockers),
- statins,
- and nitrates.
Any change in medication should always be discussed with a doctor or pharmacist.
Risk Factors
Some people are born with genetic predispositions that increase their risk of a heart attack. While these factors can’t be changed, their impact can often be reduced by making adjustments to lifestyle habits.
This not only helps protect the heart but also improves overall health.
The main recognized risk factors include:
- high bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure,
- diabetes,
- high cholesterolCholesterol is essential for the proper functioning of the human body, but it can also have harmful effects if present in excess. >>,
- overweight or obesity,
- physical inactivity,
- a diet low in plant-based foods and high in processed products,
- chronic stress,
- lack of sleep,
- and especially smoking, which remains one of the most harmful threats to heart health.
A common link between many of these risk factors is chronic inflammation, which weakens arteries and can promote the formation of clots.
The Role of Inflammation
Inflammation is a natural response by the immune system when a protective barrier in the body is damaged.
In many cases, it’s beneficial—it helps repair tissue and fight off microbes trying to invade the body.
For example, when you cut yourself, the body triggers a localized inflammatory response that helps the skin heal and eliminates bacteria using specific chemical messengers.
In this context, inflammation is helpful—and temporary.
When Inflammation Becomes a Problem
The body doesn’t always distinguish between accidental injury and ongoing stress caused by harmful habits. Sometimes, the immune system stays activated continuously, leading to chronic inflammation—a subtle but damaging process over time.
Several situations are known to fuel this kind of inflammation:
- inhaling toxins from cigarette smoke,
- exposure to environmental chemicals,
- an unbalanced diet that contributes to diabetes or high cholesterolCholesterol is essential for the proper functioning of the human body, but it can also have harmful effects if present in excess. >>,
- chronically elevated stress hormones,
- high bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure,
- or a sedentary lifestyle.
Chronic Inflammation in the Arteries
When inflammation is present day after day, it eventually weakens artery walls.
This makes arteries more permeable to cholesterolCholesterol is essential for the proper functioning of the human body, but it can also have harmful effects if present in excess. >>, encouraging the development of atherosclerotic plaques. These plaques can rupture, triggering the clotting process and potentially causing a bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood clot that suddenly blocks an artery—often the mechanism behind a heart attack.
Better Managing Inflammation
The best way to control chronic inflammation is to adopt healthier lifestyle habits, such as:
- improving your diet,
- being more physically active,
- managing stress more effectively,
- getting good sleep,
- quitting smoking,
- and keeping close track of existing conditions like diabetes or high bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure.
Changing your lifestyle is often easier said than done. It takes time, motivation, and support.

Managing High Blood Pressure (Hypertension)
High bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure (hypertension or HTN) is the leading risk factor for death worldwide. It is also one of the major causes of cardiovascular disease.
Maintaining good bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure control is therefore essential. This doesn’t rely on medication alone.

- For people without diabetes: a home bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure reading below 135/85 mmHg is recommended.
- For those with diabetes: the target is even stricter—below 130/85 mmHg.
Managing Diabetes
When diabetes is poorly controlled, it weakens bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood vessels, increasing the risk of blockages. And it’s not just the heart that can be affected: the kidneys, eyes (retina), and nerves are also at risk.
People with diabetes have a 2 to 6 times higher risk of developing cardiovascular disease compared to those without diabetes. In fact, cardiovascular disease is the leading cause of death among people living with diabetes.
Recommended bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood glucose targets:
- Before meals: between 4 and 7 mmol/L
- Two hours after meals: between 5 and 10 mmol/L
Hope on the Horizon: Type 2 Diabetes Remission
Recent studies show that type 2 diabetes is sometimes reversible. Since the condition is often caused by suboptimal lifestyle habits—diets high in refined sugars, saturated fats, processed foods, and lack of physical activity—improving these habits can lead not only to better bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood sugar control but, in some cases, to complete remission of the disease.
This remission can last for years as long as healthy habits are maintained. However, if these habits are abandoned, the disease can return quickly.
With a serious commitment to lifestyle improvement—especially in diet and exercise—many people are able to reduce or even stop diabetes medications, under medical supervision.
Recovery at Home
“The heart is broken — the patient needs a cast.”
After a heart attack, a period of physical and emotional rest is essential for healing. When someone breaks a leg, a cast is used to stabilize the injury.But since the heart can’t be immobilized directly, it’s the entire body and mind that need to be cared for gently.
The attending physician will determine the length of the recovery period based on the severity of the event and the patient’s overall health.
Month One: Active Rest
The first stage of recovery often looks like a period of home rest. Activities should remain light: simple household tasks, short walks outside, and plenty of regular rest.
This phase allows the heart muscle to begin healing under the best possible conditions.
Month Two: Gradual Resumption
During the second month, most people begin to gradually return to their usual activities. This can include getting around more, taking on more household responsibilities, and even participating in some social activities.
In most cases, returning to work is still postponed. However, for individuals who find inactivity stressful, it may be beneficial to resume some light remote work, if their condition and job allow.
Month Three: A Near-Normal Life
For many, recovery takes a bit longer. If the heart was more significantly affected, a third month of convalescence may be needed.
By this point, most daily activities can usually be resumed—such as grocery shopping, gardening, longer walks, driving, or visiting friends.
It can feel a bit like a vacation, but with the goal of regaining strength. Intense effort should still be avoided, but there’s more freedom of movement, as long as the body keeps up.
Energy gradually returns, and healing continues quietly in the background. The most important thing is to listen to your limits and not push too hard. Everyone recovers at their own pace.
Driving After a Heart Attack
Resuming driving after a heart attack depends on the type of cardiac event and the presence or absence of complications.
In the case of a STEMI (ST-elevation myocardial infarction), which involves significant damage to the coronary arteriesThe two coronary arteries, the right and the left, form the blood network that supplies the heart with oxygen and nutrients. They are located directly on the surface of the heart and branch into smaller vessels that, a minimum waiting period of one month is generally recommended before getting back behind the wheel.
For individuals with a commercial driver’s license (e.g., truck or bus drivers), this delay is typically extended to three months from the date of hospital discharge.
In cases of milder heart attacks, such as NSTEMI (non-ST-elevation myocardial infarction), where intervention was less urgent and heart damage minimal (as confirmed by echocardiography), driving may be allowed as soon as 48 hours after the procedure.
For professional drivers in these cases, driving may resume after 7 days, provided their clinical condition is stable.
Other situations—such as heart attacks without artery intervention, and without complications like valve problems or serious arrhythmias—require a case-by-case evaluation. A cardiologist will advise on the safest time to return to driving.
A Personal Decision… Within Medical Guidelines
Doctors are not required to report heart attacks to the Société de l’assurance automobile du Québec (SAAQ) or other licensing authorities.
This means it is each individual’s responsibility to follow the medical advice they’ve received. Doing so is critical—not only for their own safety but also for the safety of others on the road.
It’s the Law
If an accident occurs due to a heart-related symptom during a period when driving was medically discouraged, legal responsibility may apply.
The driver could be held accountable for the outcome, having knowingly taken the wheel against medical advice.
Time Off Work
After a heart attack, medical leave from work is usually prescribed, regardless of the type of cardiac event. This break is essential not only to allow the heart to heal but also to help the body and mind adjust to a new rhythm.
In the case of STEMI, which typically involves more serious damage, the average time off work is 4 to 8 weeks. This duration depends on the nature of the job—physically demanding or high-stress occupations often require longer recovery periods.
For NSTEMI, a smaller heart attack without significant damage confirmed by echocardiography, 1 to 2 weeks of medical leave is often considered sufficient.
A Gradual Return When Possible
After a longer medical leave—especially for physically demanding jobs—a phased return to work may be recommended. This approach allows patients to gradually test their endurance and adjust to the physical demands of their tasks, particularly when the heart has been affected.
The body also needs to adapt to new medications, some of which may cause side effects like reduced concentration, lower energy levels, or decreased tolerance to exertion.
The Role of Work-Related Stress
Chronic work-related stress can worsen cardiovascular conditions. After a heart attack, it’s important to reassess your work environment, including:
- overall atmosphere,
- mental workload,
- balance between responsibilities and available support,
- interpersonal relationships.
A healthier and more balanced work environment can help prevent recurrence and support long-term recovery.
Feeling Low Is Normal
After a STEMI-type heart attack, it’s not uncommon to experience prolonged fatigue, low energy, reduced appetite, or even weight loss. This physical slowdown can be accompanied by emotional distress, sometimes leading to a true depressive episode.
A heart attack can be a profound shock—both physically and emotionally. It often brings about a sudden sense of vulnerability, a flood of emotions, and many unsettling reflections. Recovery becomes not only a physical journey, but also an emotional one.
The many changes that need to be made after a heart attack—dietary adjustments, altered routines, changes in self-image or perceived ability—can undermine self-confidence. It’s common to feel more fragile, less in control.
It’s important to recognize these emotions as a normal part of the recovery process. In most cases, these feelings are temporary—but they should not be ignored. Talking about them—with loved ones, the healthcare team, or a mental health professional—can provide the support needed to move through them more easily.
Seeking help is not a sign of weakness. It’s an important step toward a complete and lasting recovery.
Sexual Health
Sexuality is an important part of quality of life.
After a heart attack, it is entirely normal to have questions about when it’s safe to resume sexual activity or about potential changes in sexual function, especially for men.
Resuming Sexual Activity
Sexual activity is not considered physically intense. It involves a level of effort similar to everyday activities such as walking at a slow pace, doing housework, or mowing the lawn. It is therefore categorized as moderate activity.
In most cases, sexual activity can gradually be resumed about one week after a heart attack, as long as recovery is progressing well and overall health is stable.
Erectile Dysfunction
Erectile dysfunction is common after a heart attack and can be a source of concern. Several cardiovascular risk factors are known to contribute to it, including:
- obesity,
- diabetes,
- physical inactivity,
- high cholesterolCholesterol is essential for the proper functioning of the human body, but it can also have harmful effects if present in excess. >>,
- high bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure,
- smoking,
- sleep apnea,
- and heart disease itself.
Medication and Side Effects
Some medications prescribed after a heart attack may also affect erectile function. These side effects are often temporary and may improve as the body adapts to treatment.
The Role of Mental Health
A heart attack can be a psychological shock. Stress, anxiety, or fear of “overdoing it” can interfere with intimacy. This is a common and often temporary reaction.
Talking to a healthcare professional can provide reassurance and practical advice.
Solutions Are Available
Improvements in lifestyle habits and effective management of chronic conditions like diabetes can lead to spontaneous improvement in sexual function.
There are also medical treatments such as sildenafil (Viagra), vardenafil (Levitra), or tadalafil (Cialis), which may be prescribed in certain cases.
However, these medications must never be combined with nitroglycerin, as this can cause a dangerous—and potentially fatal—drop in bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure.
In Case of Chest Pain
If chest pain similar to that experienced during a heart attack occurs within 12 to 24 hours after taking medication for erectile dysfunction,do not take nitroglycerinand call 911 immediately.
Let emergency responders know exactly when the medication was taken, as this information is crucial for proper care.
Integrating Physical Activity
Adopting an active lifestyle offers many benefits—especially after a heart attack.
Regular physical activity helps improve cardiovascular health, lower bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma.

One Change, Many Benefits
Becoming more active often leads to other healthy habits. Regular exercise frequently encourages:
- healthier eating,
- smoking reduction or cessation,
- weight loss,
- better control of diabetes and bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure.
These positive effects can appear quickly—often within the first few weeks of starting a physical activity program.
A Boost for Mental Health
Physical activity also supports mental well-being.
It helps reduce stress, improves self-esteem, and creates a sense of well-being. For many people, it becomes a cornerstone of emotional recovery after a cardiac event.
Starting at Home
Exercise can begin gently during home recovery. Light activities like slow walking or light housework are good ways to reconnect with movement.
Over time, the intensity can gradually increase, depending on tolerance. After 4 to 8 weeks, moderate-intensity activities can often be added.
The Goal: At Least 150 Minutes per Week
Guidelines recommend at least 150 minutes per week of moderate-intensity physical activity. This can be broken into bouts of 10 minutes or more, several times a day.
Consistency matters more than performance.
A good rule of thumb: the intensity is right when you can talk, but not sing, and you feel slightly out of breath. On a scale of perceived exertion, this corresponds to 3 to 5 out of 10.
Staying Safe While Exercising
Simple tips for safer activity:
- Always start with a 5–10 minute warm-up.
- Finish with a gradual cool-down.
- During strength training, avoid holding your breath (known as the Valsalva maneuver). Instead, exhale during exertion to prevent sudden spikes in bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure.
Replace Fear with Confidence
It’s common to feel nervous about being active after a heart attack. To feel more at ease, carry a cellphone and your nitroglycerin during your first outings.
Being supported by a kinesiologist is also a great way to rebuild confidence. This physical activity specialist is trained to adapt exercises to your medical condition and provide safe, personalized guidance.
Cardiac Rehabilitation Centers
Cardiac rehabilitation centers offer a structured environment for integrating physical activity as part of a comprehensive care plan. These programs include kinesiologists, dietitians, doctors, nurses, and psychologists—all working together to improve quality of life and prevent future events.
Participating in such a program is a time investment, but the benefits are often felt quickly.
No medication has the same impact on health as exercise combined with proper nutrition.
Conclusion
The key takeaway is that even small changes in lifestyle habits can have a major impact on cardiovascular health.
These changes may seem intimidating at first, but they are accessible, realistic, and sustainable when introduced gradually—at your own pace. One step at a time is enough to begin a positive transformation.
Professionals such as kinesiologists and dietitians can play a crucial role in supporting this process. Their expertise helps tailor recommendations to each individual and provides practical tools for achieving personal goals.
Finally, remember that this information does not replace medical advice. If you have concerns or need personalized follow-up, it’s always best to speak with your healthcare provider.
