Understanding the heart and coronary arteries

The heart is made mainly of special muscle. The heart pumps blood into blood vessels (arteries) which take the blood to every part of the body.
The coronary arteries supply oxygen-rich blood to the heart If these arteries are narrowed or blocked, the heart does not get enough oxygen.

This can cause angina or a heart attack. The blockage can be sudden and complete, or it can come and go – clot, break open, then clot again. “In either case, the heart tissue is dying, even if it’s just a few cells or a whole big section of the heart,” Bolger said.

Like any other muscle, the heart muscle needs a good blood supply. The coronary arteries take blood to the heart muscle. The main coronary arteries branch off from the aorta. The aorta is the large artery which takes oxygen-rich blood from the heart chambers to the body. The main coronary arteries divide into smaller branches which take blood to all parts of the heart muscle.

Understanding the heart and coronary arteries


Keep your blood pressure low

In heart failure, the release of hormones causes the blood vessels to constrict or tighten. The heart must work hard to pump blood through the constricted vessels. It is important to keep your blood pressure controlled so that your heart can pump more effectively without extra stress.

Monitor your own symptoms

Monitor your own symptoms

Check for changes in your fluid status by weighing yourself daily and checking for swelling. Call your doctor if you have unexplained weight gain (3 pounds in one day or 5 pounds in one week) or if you have increased swelling.

Maintain fluid balance

Your doctor may ask you to keep a record of the amount of fluids you drink or eat and how often you go to the bathroom. Remember, the more fluid you carry in your blood vessels, the harder your heart must work to pump excess fluid through your body. Limiting your fluid intake to less than 2 liters per day will help decrease the workload of your heart and prevent symptoms from recurring.

Limit how much salt (sodium) you eat

Limit how much salt (sodium) you eat

If you follow a low-sodium diet, you should have less fluid retention, less swelling, and breathe easier.

Monitor your weight and lose weight if needed

Learn what your “dry” or “ideal” weight is. Dry weight is your weight without extra water (fluid). Your goal is to keep your weight within 4 pounds of your dry weight. Weigh yourself at the same time each day, preferably in the morning, in similar clothing, after urinating but before eating, and on the same scale.

Call your doctor if new symptoms occur or if your symptoms worsen. Do not wait for your symptoms to become so severe that you need to seek emergency treatment.
