What is heart disease?

Bring up heart disease, và most people think of a heart attachồng. But there are many conditions that can undermine the heart"s ability khổng lồ bởi its job. These include coronary artery disease, cardiomyopathy, arrhythmia, and heart failure. Keep reading khổng lồ find out what these disorders do khổng lồ the body toàn thân 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 heart"s blood supply. This happens when there is a blockage in the coronary arteries, the vessels that carry blood to lớn 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 attaông xã symptoms

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

* Pain or pressure in the chest.

* Discomfort spreading khổng lồ the bachồng, jaw, throat, or arm.

* Nausea, indigestion, or heartburn.

* Weakness, anxiety, or shortness of breath.

* Rapid or irregular heartbeats.

Heart attaông xã symptoms in women

Women don"t always feel chest pain with a heart attachồng. Women are more likely than men to lớn 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 lớn 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 don"t know they have CAD until a heart attaông chồng 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 & 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 lớn a portion of the heart. Without immediate treatment, that part of the heart muscle could be damaged or destroyed.

Don"t wait lớn be sure

The best time to treat a heart attaông chồng is as soon as symptoms begin. Waiting lớn be sure can result in permanent heart damage or even death. If you think you may be having a heart attaông xã, Call 911. And don"t 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 it"s not the same as a heart attaông chồng. SCD occurs when the heart"s electrical system goes haywire, causing it lớn beat irregularly & dangerously fast. The heart"s pumping chambers may quiver instead of pumping blood out to lớn the body toàn thân. Without Cquảng bá & restoration of a regular heart rhythm, death can occur in minutes.

Arrhythmia: Erratic heart beat

Regular electrical impulses cause your heart khổng lồ 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, & that can take a serious toll on the toàn thân. Let your doctor know if you"ve noticed your heart beating abnormally.


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 sầu disease.

Heart failure

Heart failure doesn"t mean your heart stops working. It means the heart can"t pump enough blood lớn meet the body"s needs. Over time, the heart gets bigger lớn hold more blood, it pumps faster khổng lồ increase the amount of blood moving out of it, & 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 that"s present at birth. The problem could be a leaky heart valve sầu, 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 infection, but there are ways lớn reduce this risk.

Testing: Electrocardiogram (EKG)

An EKG (also ECG) is a painless demo that uses electrodes placed on the skin khổng lồ record the heart"s electrical activity. The chạy thử provides information about your heart rhythm và damage lớn the heart muscle. An EKG can help your doctor diagnose a heart attack and evaluate abnormalities such as an enlarged heart. The results can be compared khổng lồ future EKGs to lớn trachồng changes in the condition of your heart.

Testing: Stress test

The bít tất tay kiểm tra measures how your heart responds to exertion. If you have an exercise găng tay kiểm tra, you"ll either walk on a treadmill or ride a stationary bike while the cấp độ of difficulty increases. At the same time, your EKG, heart rate, và blood pressure will be monitored as your heart works harder. Doctors use a căng thẳng chạy thử khổng lồ evaluate whether there is an adequate supply of blood to the heart muscle.

Testing: Holter monitor

Testing: Chest X-ray

A chest X-ray is a picture of your heart, lungs, và chest bones that"s made by using a very small amount radiation. Chest X-rays can be used lớn look for heart và lung abnormalities.

In this image, the bulge seen on the right side is an enlarged left ventricle, the heart"s main pumping chamber.

Testing: Echocardiogram

An echocardiogram uses sound waves (ultrasound) to lớn generate moving images of the heart. The thử nghiệm can assess the chambers và valves of your heart & how well your heart muscle & heart valves are working. It"s useful in diagnosing và evaluating several types of heart disease, as well as evaluating the effectiveness of treatments.

Testing: Cardiac CT

Cardiac computerized tomography (known as cardiac CT) takes detailed images of the heart và its blood vessels. A computer stacks the images lớn 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.

Testing: Cardiac catheterization

Cardiac catheterization helps diagnose & treat some heart conditions. The doctor guides a narrow tube, called a catheter, through a blood vessel in your arm or leg until it reaches the coronary arteries. Dye is injected into lớn each coronary artery, making them easy khổng lồ see with an X-ray. This reveals the extent và severity of any blockages. Treatments such as angioplasty or stenting can be done during this procedure.

Living with heart disease

Most forms of heart disease are chronic. In the beginning, symptoms may be too mild to lớn affect everyday life. And in many cases, long-term treatment can keep symptoms under control. But if the heart begins to fail, patients may develop shortness of breath, fatigue, or swelling in ankles, feet, legs, và abdomen. Heart failure can be managed with medication, lifestyle changes, surgery, và in certain cases, a heart transplant.

Treatment: Medicines

Medications play a huge role in treating heart disease. Some drugs help lower blood pressure, heart rate, & cholesterol levels. Others can keep abnormal heart rhythms under control or prevent clotting. For patients who already have sầu some heart damage, there are medications khổng lồ improve the pumping ability of an injured heart.

Treatment: Angioplasty

Angioplasty is used to open a blocked heart artery and improve blood flow khổng lồ the heart. The doctor inserts a thin catheter with a balloon on the kết thúc inlớn the artery. When the balloon reaches the blockage, it is expanded, opening up the artery and improving blood flow. The doctor may also insert a small mesh tube, called a stent, khổng lồ help keep the artery open after angioplasty.

Treatment: Bypass surgery

Bypass surgery is another way khổng lồ improve the heart"s blood flow. It gives blood a new pathway when the coronary arteries have sầu become too narrow or blocked. During the surgery, a blood vessel is first moved from one area of the toàn thân -- such as the chest, legs, or arms -- & attached to lớn the blocked artery, allowing it to lớn bypass the blocked part.

Who"s at risk for heart disease?

Men have a higher risk of having a heart attaông xã than women, & at an earlier age. But it"s important to note that heart disease is the No. 1 killer of women, too. People with a family history of heart ailments also have a higher risk of heart trouble.

Risk factors you can control

High cholesterol & high blood pressure are major risk factors for heart disease. Being overweight, obese, or physically inactive sầu all increase your risk. So does diabetes, especially if your glucose levels are not well controlled. Discuss your risks with your doctor và develop a strategy for managing them. There are many steps you can take khổng lồ protect your heart.

Smoking & your heart

If you smoke, your risk of heart disease is 2 khổng lồ 4 times greater than a nonsmoker"s. And if you smoke around loved ones, you"re increasing their risk with secondh& smoke. Each year in the U.S., more than 135,000 people die from smoking-related heart disease. But it"s never too late to lớn quit. Within 24 hours of quitting, your heart attaông chồng risk begins to lớn fall.

Life after a heart attack

It is possible lớn regain your health after a heart attack. By avoiding cigarettes, becoming more active sầu, và watching what you eat, you can give sầu your heart & overall health a big boost. One of the best ways to lớn learn how to lớn make these changes is lớn take part in a cardiac rehab program. Ask your doctor for recommendations.
