Angina is chest pain or discomfort that is caused by reduced blood flow to the heart muscle. This occurs when arteries that carry blood to your heart become narrowed and blocked due to atherosclerosis or a blood clot. Angina is not the same thing as a heart attack, but it may feel like one.  Angina symptoms include squeezing, pressure, heaviness, tightness or pain in your chest. Symptoms often occur during exertion and can be felt when the heart works harder and faster, such as when you exercise or climb stairs.
Angina may be a warning that you have heart disease. If you are having symptoms, talk to your Spectrum Health primary care physician right away. New or different symptoms may signal a more serious condition or heart attack. If you have unexplained chest pain, seek medical attention right away.

Medication Management
Along with very important lifestyle changes, there are a variety of medicines used to help treat heart conditions. Medicines for heart disease are used to ease discomfort or lessen symptoms, but some can also be essential in preventing life-threatening episodes. It is important to take your medicines exactly as prescribed, and work with your doctor on both lifestyle and medicine changes.

Percutaneous Coronary Intervention (Angioplasty/Stent Placement)
An angioplasty is a less invasive procedure that opens a clogged artery with a small balloon. This can be done through the wrist (radial) or the groin (femoral) artery. Typically this procedure includes the placement of stents.

Enhanced External Counterpulsation Therapy (EECP)
This non-invasive procedure is meant to decrease the severity and occurrences of angina episodes. Three pairs of inflatable cuffs are placed around the legs. These cuffs expand and retract in an effort to improve blood flow and return more blood to the heart. 

What Is Angina?

Angina is chest pain usually caused by narrowing of blood vessels in the heart from blockage or spasm. Less blood can reach the heart, so it has less oxygen for pumping blood. Angina may mean serious heart problems and needs immediate attention.

What Causes Angina?

Coronary artery disease from atherosclerosis (i.e., fatty deposits in blood vessels to the heart), abnormal heart rhythms (arrhythmias), fewer oxygen-carrying red blood cells (anemia), and spasms of the coronary arteries can reduce blood flow.

At increased risk for angina are men older than age 60, women after menopause, people with a family history of heart disease, people who eat high-fat high-cholesterol foods, people who don’t exercise regularly, smokers, and people with diabetes, high blood pressure (hypertension), or high cholesterol levels.

What Are the Symptoms of Angina?

The primary symptom is a feeling of tightness, dull ache, or heaviness that begins in the chest and sometimes spreads to the back, neck, left shoulder, and down the arms (especially left arm). Pain may be dull or sharp or feel like heartburn or indigestion. Some people describe a smothering or crushing pain. It may begin slowly or be severe and sudden. Sweating, nausea, feeling faint or weak, dizziness, or shortness of breath may also occur.

How Is Angina Diagnosed?

The health care provider makes a diagnosis by checking symptoms, doing examinations and laboratory and other tests. Tests include electrocardiograms (ECGs) and treadmill or exercise tests. A heart catheterization (checking the heart’s blood flow by putting a device through an artery into the heart) may also be done if the initial tests show signs of blocked heart (coronary) arteries.

How Is Angina Treated?

The goal is to improve blood flow to the heart or to reduce the heart’s work. Resting or reducing activity is the first treatment.

Aspirin improves blood flow. Nitrates such as nitroglycerin can also help blood flow. Other medications such as beta blockers slow down the heartbeat and the work done by the heart. Medicine for other diseases (e.g., hypertension, arrhythmias, diabetes, high cholesterol) may be given if these diseases are present.

Anyone with angina should take aspirin daily unless told not to by a health care provider.

Lifestyle changes (exercise, diet, weight control, quitting smoking) are important.

If medicine doesn’t work, surgery (angioplasty, an operation to open clogged blood vessels with a balloonlike device) may be needed. A small wire mesh tube, called a stent, is often inserted into the blocked artery after it has been opened to prevent it from narrowing again. Open heart surgery (coronary artery bypass graft, or CABG) may be necessary for severely blocked arteries.

DOs and DON’Ts in Managing Angina:
  • DO change your diet and reduce weight to lower blood pressure and improve blood fat and sugar levels.
  • DO begin an exercise program under the guidance of your physician to strengthen the heart and reduce weight, blood pressure, blood fat levels, and stress.
  • DO stop smoking.
  • DO take your medicines as directed.
  • DO call your health care provider if medicines don’t control your pain.
  • DO call 911 or get to the emergency room if you take nitroglycerin three times in a row without symptom relief.
  • DO call your health care provider immediately if you have new or worsening symptoms that your medicine doesn’t control.
  • DON’T smoke, drink alcohol in excess, or eat salty or high-fat foods.
  • DON’T ignore your symptoms.
  • DON’T use Viagra®, Levitra®, or Cialis® if you take nitroglycerin.
