Heart Attack Q & A

What is a heart attack?

A heart attack, or myocardial infarction, is a potentially fatal condition that occurs when there’s a blockage that prevents blood flow through your heart.

Symptoms of a heart attack include:

  • Chest pain
  • Feeling of tightness or pressure in your chest
  • Squeezing or aching feeling in your chest
  • Nausea
  • Indigestion or heartburn
  • Abdominal pain
  • Difficulty breathing
  • Cold sweat
  • Extreme tiredness
  • Feeling lightheaded or dizzy

The feeling of pain and pressure can spread into your arms and may go into your neck and back as well. If you experience any symptoms that indicate you could be having a heart attack, it’s vital to call 911 for emergency medical attention.

What causes a heart attack?

A heart attack is usually the result of a blockage in one or more coronary arteries, although in some cases, it occurs due to a spasm of the coronary artery.

The most common cause of a blockage is a buildup of plaque, a substance composed largely of cholesterol. Plaque buildup occurs gradually and leads to a narrowing of the arteries, or atherosclerosis, which causes coronary artery disease (CAD).

If an area of plaque ruptures, it forms a blood clot that can block blood flow through the coronary artery. This blockage causes ischemia, meaning your heart isn’t getting enough oxygen and nutrients.

What are the risk factors for having a heart attack?

Several factors increase your chances of suffering a heart attack, including:

  • Age, as men over 45 and women over 55 have a higher risk
  • Smoking
  • High blood pressure (hypertension)
  • High levels of LDL cholesterol
  • High levels of triglycerides
  • Low levels of HDL cholesterol
  • Obesity
  • Diabetes
  • Metabolic syndrome
  • Family history of heart attacks
  • Physical inactivity
  • Chronic stress
  • Use of stimulant drugs
  • Having an autoimmune condition such as lupus

Heart attacks can result in heart failure or the development of arrhythmias and may cause cardiac arrest.

How are heart attacks treated?

Initially, you might receive medications such as aspirin, thrombolytics, antiplatelet agents, or heparin to dissolve blood clots and reduce the stickiness of your blood. You may also receive drugs that improve blood flow, lower blood pressure, and relax your heart muscle.

You might need surgery to treat a heart attack. Coronary angioplasty and stenting aim to open up the blocked artery and keep it open.

In some cases, you might need coronary artery bypass grafting (CABG), a surgical procedure that involves taking a healthy piece of an artery from elsewhere and using it to bypass the blocked artery.

Regular screening can detect the signs of coronary artery disease that may lead to a heart attack, so call Harlem Cardiology on Madison Avenue or book an appointment online today for a checkup.
