A heart attack can happen in an instant, but recovering from one unfolds over weeks, months, and ultimately a lifetime. For patients and families, the experience often comes with more questions than answers … What happens the moment I arrive at the hospital? How serious is this, really? And, once I go home, does life just go back to normal?
Yonathan Litwok, MD, Director of the Cardiac Intensive Care Unit at The Valley Hospital, and cardiologist Kate Raiti-Palazzolo, MD, have the answers. Here, they walk us through the full picture-– from those first critical minutes in the emergency room, to hospital treatment and recovery, to the lifestyle and lifelong care changes that follow.

The first critical hours
A heart attack occurs when the heart muscle isn’t receiving enough blood and oxygen, most commonly due to a blockage in one of the coronary arteries. “Chest pain is the most common presentation,” Dr. Litwok explains, though symptoms can also appear as arm, jaw, or back pain, or even sweating, dizziness, and indigestion.
Time matters enormously. Dr. Litwok strongly recommends calling 911 rather than driving to the hospital, since paramedics can perform an EKG enroute and alert the hospital team before arrival. Once in the emergency room, patients undergo EKGs and blood tests, including a specific marker called troponin that indicates heart stress.
“Cardiologists have gotten really, really good at opening up those blockages,” Dr. Litwok assures, with a goal of restoring blood flow within 90 minutes to give the heart the best chance at recovery.
How cardiologists find and treat the blockage
If a heart attack is suspected, patients typically undergo a coronary angiogram. This is a procedure where a thin catheter is guided through the wrist or groin to capture images of the coronary arteries. In most cases, if a blockage is found, it can be treated immediately with a stent, a small mesh tube that expands to restore blood flow. In rarer cases involving multiple significant blockages, coronary bypass surgery may be recommended instead.
Recovery in the Cardiac ICU
After the procedure, patients move to the Cardiac Intensive Care Unit, where a specialized team closely monitors vital signs and symptoms for the first 24 to 48 hours. An echocardiogram is typically performed to assess how well the heart is pumping and how the valves are functioning. New medications are started during this time as well.
Preparing for discharge
Once stable, patients transition to a lower-intensity unit where cardiac rehab staff help them begin walking and physical activity, ensuring they can safely manage stairs and daily tasks before discharge. Patients also begin a new medication regimen – typically aspirin plus a second blood-thinning medication like Plavix or Brilinta – designed to keep stents from clogging. “You really have to be religious about taking the aspirin and the other medication every single day,” Dr. Litwok emphasizes. Follow-up with a cardiologist within one to two weeks after discharge is standard.
Life after a heart attack: recovering at home
Once home, care shifts toward long-term risk reduction. Dr. Raiti-Palazzolo focuses on reviewing medications, managing cholesterol, and encouraging a Mediterranean-style diet rich in lean protein, vegetables, legumes, and whole grains. Physical activity, ideally through cardiac rehab, plays a central role, as does smoking cessation for those who previously smoked.
The emotional side of heart attack recovery
A heart attack affects more than the body. “A lot of patients have a lot of anxiety, a lot of depression, and fear of having another heart attack,” Dr. Raiti-Palazzolo notes. Cardiac rehab provides not just physical supervision but meaningful emotional support, helping patients process the experience alongside others who understand it firsthand.
Is cardiac rehab worth it?
When asked if cardiac rehab is “worth it,” Dr. Raiti-Palazzolo has one word of advice: absolutely. Cardiac rehab offers supervised, monitored exercise for patients hesitant to resume activity, along with patient education, nutrition guidance, and risk factor management. Research shows it reduces both mortality and the risk of a future cardiovascular event.
A common misconception about heart disease
Many patients assume that once a blockage is fixed, the problem is resolved. In reality, heart disease is a chronic condition. “This is a chronic disease, and it's not just opening up the vessel,” cautions Dr. Raiti-Palazzolo. Ongoing management of blood pressure, cholesterol, diet, and activity – paired with regular cardiologist visits for life – is essential to preventing future events.
The bottom line: consistency matters
Both physicians offer the same core message: Consistency matters most. “If you have good outpatient follow-up, if you see your cardiologist regularly, if you take your medications and take care of yourself, we can hopefully assure that you'll have many, many more healthy and happy years,” Dr. Litwok reinforces. Dr. Raiti-Palazzolo agrees, framing the relationship with a cardiologist as a lasting partnership focused on one goal: helping patients live the long, healthy life they want.
