0 What Is Heart Disease

Bring up heart disease, and most people think of a heart attack. But there are many conditions that can undermine the hearts ability to do its job. These include coronary artery disease, cardiomyopathy, arrhythmia, and heart failure. Keep reading to find out what these disorders do to the body and how to recognize the warning signs.

What Is a Heart Attack?

Every year, more than 1 million Americans have a heart attack – a sudden interruption in the hearts blood supply. This happens when there is a blockage in the coronary arteries, the vessels that carry blood to the heart muscle. When blood flow is blocked, heart muscle can be damaged very quickly and die. Prompt emergency treatments have reduced the number of deaths from heart attacks in recent years.

Heart Attack Symptoms


A heart attack is an emergency even when symptoms are mild. Warning signs include:

    * Pain or pressure in the chest.
    * Discomfort spreading to the back, jaw, throat, or arm.
    * Nausea, indigestion, or heartburn.
    * Weakness, anxiety, or shortness of breath.
    * Rapid or irregular heartbeats.

Heart Attack Symptoms in Women

Women dont always feel chest pain with a heart attack. Women are more likely than men to have heartburn, loss of appetite, tiredness or weakness, coughing, and heart flutters. These symptoms should not be ignored. The longer you postpone treatment, the more damage the heart may sustain.

Signs of Coronary Artery Disease

A precursor to a heart attack, coronary artery disease or CAD occurs when  sticky plaque builds up inside the coronary arteries. This narrows the arteries, making it more difficult for blood to flow through. Many people dont know they have CAD until a heart attack strikes. But there are warning signs, such as recurring chest pain caused by the restricted blood flow. This pain is known as angina.

Inside a Heart Attack

The plaque deposited in your arteries is hard on the outside and soft and mushy on the inside. Sometimes the hard outer shell cracks. When this happens, a blood clot forms around the plaque. If the clot completely blocks the artery, it cuts off the blood supply to a portion of the heart. Without immediate treatment, that part of the heart muscle could be damaged or destroyed.

Dont Wait to Be Sure

The best time to treat a heart attack is as soon as symptoms begin. Waiting to be sure can result in permanent heart damage or even death. If you think you may be having a heart attack, call 911. And dont try driving yourself to the hospital. When you call 911, the EMS staff can start emergency care as soon as they reach you.

Sudden Cardiac Death

Sudden cardiac death (SCD) accounts for half of all heart disease deaths in the U.S., but its not the same as a heart attack. SCD occurs when the hearts electrical system goes haywire, causing it to beat irregularly and dangerously fast. The hearts pumping chambers may quiver instead of pumping blood out to the body. Without CPR and restoration of a regular heart rhythm, death can occur in minutes.

Arrhythmia: Erratic Heart Beat

Regular electrical impulses cause your heart to beat. But sometimes those impulses become erratic. The heart may race, slow down, or quiver. Arrhythmias are often harmless variations in rhythm that pass quickly. But some types make your heart less effective at pumping blood, and that can take a serious toll on the body. Let your doctor know if youve noticed your heart beating abnormally.

Cardiomyopathy

Cardiomyopathy is a disease involving changes in the heart muscle. These changes may interfere with the heart’s ability to pump effectively, which can lead to a chronic condition called heart failure. Cardiomyopathy is sometimes associated with other chronic conditions, such as high blood pressure or heart valve disease.

Heart Failure

Heart failure doesnt mean your heart stops working. It means the heart cant pump enough blood to meet the bodys needs. Over time, the heart gets bigger to hold more blood, it pumps faster to increase the amount of blood moving out of it, and the blood vessels narrow. The  heart muscle may also weaken, reducing the blood supply even more. Most cases of heart failure are the result of coronary artery disease and heart attacks.

Congenital Heart Defect

A congenital heart defect is one thats present at birth. The problem could be a leaky heart valve, malformations in the walls that separate the heart chambers, or other heart problems. Some defects are not found until a person becomes an adult. Some need no treatment. Others require medicine or surgery. People with congenital heart defects may have a higher risk of developing complications such as arrhythmias, heart failure, and heart valve

Testing: Holter Monitor

A Holter monitor is a portable heart rhythm recorder. If your doctor suspects a heart rhythm problem, she may ask you to wear one for 1 or 2 days. It  records the hearts continuous electrical activity day and night, compared with an EKG, which is a snapshot in time. The doctor will probably also ask you to keep a log of your activities and to note any symptoms and when they occur.

Testing: Cardiac CT

Cardiac computerized tomography (known as cardiac CT) takes detailed images of the heart and its blood vessels. A computer stacks the images to create a 3-D picture of heart. A cardiac CT can be used to look for plaque or calcium buildup in the coronary arteries, heart valve problems, and other types of heart disease.

Smoking and Your Heart

If you smoke, your risk of heart disease is 2 to 4 times greater than a nonsmokers. And if you smoke around loved ones, youre increasing their risk with secondhand smoke. Each year in the U.S., more than 135,000 people die from smoking-related heart disease. But its never too late to quit. Within 24 hours of quitting, your heart attack risk begins to fall.

Heart Disease Prevention

The key to preventing heart disease is a healthy lifestyle. This includes a nutritious diet, at least 30 minutes of exercise most days of the week, not smoking, and controlling high blood pressure, cholesterol, and diabetes. If you drink alcohol, do so in moderation – no more than one drink a day for women, two drinks a day for men. Ask your friends and family for help in making these changes. Theyll benefit, too.

Diet and Your Heart

What you eat makes a difference. Be sure you get plenty of whole grains, vegetables, legumes, and fruits to help keep your heart healthy.  Plant oils, walnuts, other nuts, and seeds can also help improve cholesterol levels. And dont forget to eat fish at least a couple of times each week for a good source of heart-healthy protein.
