At the first sign of a heart attack…call 911. Do not let COVID scare you away from hospitals. Hospitals are, and will remain, the safest place for you to go for an emergency.
Heart Attack Symptoms:
- Chest discomfort which can feel like pressure, squeezing, fullness or pain
- Pain or discomfort in one or both arms, the back, neck, jaw or stomach
- Shortness of breath
- Cold sweats, nausea or lightheadedness may also be present
Symptoms are sometimes different for women than men. Chest pain or discomfort is the most common sign in men and women, but women are somewhat more likely to experience some of the other common symptoms, such as shortness of breath and back or jaw pain.
Even if you are not certain whether your symptoms could be a heart attack, it is best to get evaluated to know for sure. Time is important, as every minute matters. Do not drive, call 911. An emergency medical services (EMS) team can get treatment started once they arrive, much sooner than for someone who drives by car. Also, patients that arrive to the hospital via EMS are taken directly to a room for treatment. Those that arrive via car must check in at registration and be triaged with the rest of the emergency room patients waiting. For these reasons alone, it is best to call 911.
A heart attack (also called a myocardial infarction, or MI) is caused by heart disease which is the leading cause of death among both men and women in the United States. According to the American Heart Association, each year approximately 785,000 people have their first heart attack and nearly 470,000 of those will go on to have another one.
Heart attacks are usually caused by fatty buildups or atherosclerosis in the arteries. These buildups of plaque narrow the arteries decreasing the blood flow, and thus oxygen, to the heart. If this plaque ruptures it can cause a blood clot to form and further block blood flow. When blood flow is completely blocked to part of the heart muscle, a heart attack occurs. This section of heart muscle without blood flow begins to die. The longer the blood flow is blocked the worse the damage becomes; permeant heart damage and even death can occur.
Want to know if you are at increased risk for a heart attack? The common risk factors are divided into three categories, major, modifiable, and contributing. The more risk factors you have, the greater your risk is.
Major Risk Factors:
- Increasing age
- Male gender
- Heredity (including race)
If your parents have heart disease your risk is increased
African-Americans, Mexican-Americans, American Indians, native Hawaiians and some Asian-Americans are all at a higher risk, partly due to higher rates of severe high blood pressure, obesity and diabetes
Modifiable Risk Factors:
- Tobacco smoke
- High cholesterol
- High blood pressure
- Physical inactivity
- Obesity
- Diabetes
Contributing Risk Factors:
- Stress
- Alcohol
- Diet and nutrition
Treatment for a heart attack varies depending on the type of heart attack you have, although there can be some overlap. The most commonly known types of heart attacks are ST-segment elevation myocardial infarctions (STEMI) and non-ST segment elevated myocardial infarctions (NSTEMI). A STEMI is a very serious form of a heart attack in which a coronary artery is completely blocked and therefore a large part of the heart muscle is unable to receive blood. A NSTEMI is a partial blockage of blood flow to the heart. Commonly used techniques to restore blood flow include clot-busting drugs (thrombolytics), balloon angioplasty (PCI), surgery or a combination of treatments.
A STEMI requires immediate medical treatment. Emergent revascularization is needed to restore blood flow through the blocked artery. Most likely treatment would involve a trip to the cath lab, a department specializing in cardiac catheterization. In the cath lab, a diagnostic angiogram can be done to better examine your heart’s blood flow and how well it is pumping. Depending on these results, a treatment option will be decided: medical management only, percutaneous coronary intervention (PCI), or coronary artery bypass grafting (CABG).
A NSTEMI on the other hand, usually involves one of two treatment options: drug therapy (antiplatelet agents and anticoagulants) to prevent blood clot formation or early invasive treatment starting with drug therapy but also proceeding to PCI with stent placement or CABG.
Dual antiplatelet therapy (DAPT) is also a common treatment among patients post heart attack. This treatment involves two types of antiplatelet medications taken together to prevent blood from clotting. One antiplatelet medication is aspirin. Almost everyone post heart attack is treated with aspirin for the rest of their lives. An additional type of antiplatelet medication, called a P2Y12 inhibitor, is also prescribed for months to years in addition to the aspirin. These P2Y12 inhibitors include clopidogrel (Plavix), prasugrel (Effient), and ticagrelor (Brilinta). The medication type and duration will depend on your specific condition and other risk factors.
If you have a heart attack, make preventing another one your top priority. Most people go on to live a long, productive life. However, about 20 percent of patients 45 years old and older have another heart attack within 5 years of their first.
According to the American Heart Association, here are five things you can do to prevent another heart attack:
- Take your medications as prescribed. Certain medications can greatly lower your risk of another cardiac event. That is why it’s important for you to understand your medications and take them correctly.
- Attend your follow-up appointments. Attending your follow-up appointments will help your doctors keep track of your condition and recovery.
- Participate in cardiac rehabilitation. Cardiac rehabilitation is a medically supervised program designed to help you recover after a heart attack. You should have received a referral to cardiac rehab when you were discharged from the hospital – if you didn’t, ask your doctor about it.
- Manage your risk factors. After a heart attack, it is important to manage risk factors (such as high blood pressure, high cholesterol, and diabetes) by taking your medications, quitting smoking, eating healthier food and getting advice.
- Get support. It is normal to feel scared, overwhelmed and/or confused after a heart attack. Getting support from loved ones or from people who have also experienced a heart attack can help you cope. Connect with other heart attack survivors and caregivers through the American Heart Association Support Network.
A heart attack is a very serious condition and requires fast medical treatment. If you or a loved one think you are experiencing one call 911 and get to the hospital as fast as possible. Do not let COVID or anything else keep you from receiving the life-saving treatment you need.
