Heart Attack - Methodist Le Bonheur Healthcare

Heart Attack

Advanced, Accredited Heart Attack Treatment

Each year in the United States, more than 800,000 people have a heart attack. Knowing what to do when this emergency happens can be lifesaving.

A heart attack, or myocardial infarction, occurs when blood flow to part of the heart is cut off or restricted. This blood flow restriction causes damage to the heart muscle, and the longer the heart goes without blood and oxygen, the greater the damage.

Quick treatment for a heart attack can limit the damage, which is why it’s crucial to call 911 when experiencing symptoms such as chest pain or shortness of breath. Emergency treatment for a heart attack can begin during transport to the hospital.

Once you arrive at the hospital, providers with Methodist Le Bonheur Healthcare will perform advanced diagnostic tests to confirm a heart attack and provide prompt treatment to limit damage.

Heart Attack Types

There are two primary types of heart attacks, named based on how they appear on an electrocardiogram (EKG):

  • ST-segment elevation myocardial infarction (STEMI) is the most common type of heart attack. STEMI heart attacks occur when a coronary artery is completely blocked, cutting off the flow of oxygenated blood to part of the heart.
  • Non-ST segment elevation myocardial infarction (NSTEMI) is less common and often less severe than a STEMI heart attack. NSTEMI heart attacks occur when part of a blood vessel is blocked, limiting blood flow.

All heart attacks are what’s known as “acute coronary syndrome,” occurring when blood flow to the heart is temporarily diminished or blocked. This differs from cardiac arrest, which occurs when the heart stops due to an irregular heart rhythm.

Signs and Symptoms

While chest pain or discomfort are common symptoms, other warning signs of a heart attack may include:

  • Dizziness
  • Extreme fatigue
  • Lightheadedness
  • Nausea or vomiting
  • Shortness of breath
  • Shoulder, jaw, neck, stomach or arm pain
  • Sweating with seemingly no cause

Many people have pain in the center or left side of the chest, but it may feel like pressure, squeezing or fullness.

Women may experience symptoms of a heart attack differently — for one, pain may be felt on the right side of the chest. Women having a heart attack are also more likely to experience symptoms such as dizziness, nausea, fatigue and upper back pain. These symptoms may be mistaken for symptoms of a less serious medical condition like the flu or heartburn.

Causes and Risk Factors

Coronary artery disease (CAD) is the most common cause of a heart attack. CAD affects more than 20 million people in the United States, making it the most common type of heart disease.

Coronary artery disease develops due to atherosclerosis, caused by plaque buildup in blood vessels. Over time, this plaque buildup causes the arteries to narrow, restricting blood flow. In some cases, plaque can break apart and form a blood clot, cutting off blood flow to the heart and increasing the risk of a heart attack.

Other causes of heart attack may include:

  • Coronary artery embolism occurs when a blood clot forms somewhere in the body and travels up to the coronary arteries, cutting off blood flow to the heart.
  • Coronary artery spasm occurs when a spasm causes the coronary artery to tighten, limiting blood flow. The spasm doesn’t always cause symptoms.
  • Spontaneous coronary artery dissection (SCAD) occurs when the coronary artery wall spontaneously tears. This can cause blood clotting between layers of the artery wall, which keeps blood from reaching the heart muscle.

Certain factors increase your heart attack risk, including:

  • Being overweight or obese
  • Being physically inactive
  • Eating a diet high in saturated fat, sodium and added sugar
  • Having a personal or family history of heart disease
  • Having high blood pressure
  • Having high total or LDL cholesterol or high triglycerides
  • Smoking

Women also have unique risk factors for heart attack, including a history of preeclampsia or gestational diabetes during pregnancy.

Reducing Risks of Heart Attack

Preventing a heart attack starts with learning your risk factors and taking steps to mitigate those risks. You can lower your risk by:

  • Being physically active
  • Eating a diet based on fruits and vegetables, lean protein and whole grains
  • Getting to — and maintaining — a healthy weight
  • Limiting your alcohol consumption
  • Not smoking

If you have chronic conditions such as high blood pressure or high cholesterol, work with a medical provider to effectively manage them through medications and other treatment options.

Heart Attack Intervention Information to Know

If you’re experiencing symptoms that may be related to a heart attack, doctors can use diagnostic testing to confirm a diagnosis quickly. Testing may include:

  • Advanced cardiac imaging tests, such as a CT scan, to look for heart damage
  • Blood tests to look for specific proteins released during a heart attack
  • EKG to analyze heart rhythms

By reviewing an EKG, a cardiologist can also confirm whether you’re experiencing a STEMI or NSTEMI heart attack based on whether the ST segment is elevated.

CPR is a lifesaving procedure performed when the heart stops beating. If performed immediately on someone experiencing cardiac arrest, it can double or even triple the chance of survival. Hands-Only CPR is essentially CPR without rescue breaths. It can be performed by anyone in two simple steps:

  1. Call 911
  2. Push hard and fast in the center of the chest to the beat of the Bee Gees’ song “Stayin’ Alive,” Taylor Swift’s “Fearless,” Gnarles Barkley’s “Crazy” or Justin Timberlake’s “Rock Your Body.” These songs are all around 100 beats per minute — the minimum rate you should push on the chest during Hands-Only CPR.

If you’re having a heart attack, your treatment plan will vary depending on the specific type of heart attack and its severity. Treatment may include:

  • Angioplasty, a catheter-based procedure to reopen blocked arteries, sometimes placing a mesh tube called a stent to keep arteries open
  • Artificial heart valve surgery, a procedure to replace a diseased heart valve
  • Atherectomy, a catheter-based procedure that uses a rotating blade tip to cut away plaque
  • Bypass surgery, an open-heart procedure that uses a blood vessel from elsewhere in the body to bypass a blocked coronary artery
  • Medications to mitigate risk factors such as high cholesterol or high blood pressure and to prevent further damage to the heart
  • Radiofrequency ablation, a catheter-based procedure that uses radio waves to destroy heart muscle cells causing an abnormal heart rhythm
  • Transmyocardial revascularization, a procedure using a laser to drill holes into the heart’s pumping chamber, improving blood flow

In some cases, minimally invasive procedures may be used as an alternative to open-heart surgery, offering patients a quicker recovery and other benefits. 

Your team of providers at Methodist Le Bonheur will consider several factors to create a treatment plan for you, including your overall health and your risk of future cardiovascular events. In cases of severe heart damage, we also offer advanced procedures such as a heart transplant.
