What is heart disease?
Bring up heart disease, & most people think of a heart attachồng. But there are many conditions that can undermine the heart"s ability to lớn vì its job. These include coronary artery disease, cardiomyopathy, arrhythmia, and heart failure. Keep reading lớn find out what these disorders vì chưng khổng lồ the body toàn thân & how khổng lồ recognize the warning signs.
What is a heart attack?
Every year, more than 1 million Americans have sầu a heart attaông xã – 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 lớn the heart muscle. When blood flow is blocked, heart muscle can be damaged very quickly & die. Prompt emergency treatments have sầu reduced the number of deaths from heart attacks in recent years.
Heart attaông xã 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 attaông chồng symptoms in women
Women don"t always feel chest pain with a heart attachồng. Women are more likely than men 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 khổng lồ a heart attachồng, 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 xã strikes. But there are warning signs, such as recurring chest pain caused by the restricted blood flow. This pain is known as angimãng cầu.
Inside a heart attack
The plaque deposited in your arteries is hard on the outside and soft và 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 khổng lồ 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 attaông xã, Call 911. And don"t try driving yourself lớn the hospital. When you gọi 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 attack. SCD occurs when the heart"s electrical system goes haywire, causing it to lớn beat irregularly and dangerously fast. The heart"s pumping chambers may quiver instead of pumping blood out to the toàn thân. Without Clăng xê & 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, and that can take a serious toll on the body. 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 lớn pump effectively, which can lead to lớn 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 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 to lớn hold more blood, it pumps faster to lớn 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 & 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 sầu a higher risk of developing complications such as arrhythmias, heart failure, & heart valve infection, but there are ways lớn reduce this risk.
Testing: Electrocardiogram (EKG)
An EKG (also ECG) is a painless thử nghiệm that uses electrodes placed on the skin to lớn record the heart"s electrical activity. The kiểm tra provides information about your heart rhythm and damage khổng lồ 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 to lớn future EKGs khổng lồ track changes in the condition of your heart.
Testing: Stress test
The bao tay thử nghiệm measures how your heart responds lớn exertion. If you have an exercise ức chế 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 to 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 to 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.
An echocardiogram uses sound waves (ultrasound) lớn generate moving images of the heart. The demo can assess the chambers & valves of your heart và how well your heart muscle and 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 and its blood vessels. A computer stacks the images lớn create a 3-D picture of heart. A cardiac CT can be used lớn 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 lớn see with an X-ray. This reveals the extent and 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 khổng lồ affect everyday life. And in many cases, long-term treatment can keep symptoms under control. But if the heart begins lớn 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.
Medications play a huge role in treating heart disease. Some drugs help lower blood pressure, heart rate, and cholesterol levels. Others can keep abnormal heart rhythms under control or prsự kiện clotting. For patients who already have some heart damage, there are medications khổng lồ improve sầu the pumping ability of an injured heart.
Angioplasty is used to open a blocked heart artery và improve sầu blood flow lớn the heart. The doctor inserts a thin catheter with a balloon on the kết thúc inkhổng lồ 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 body toàn thân -- such as the chest, legs, or arms -- and attached khổng lồ 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 attachồng than women, and at an earlier age. But it"s important khổng lồ 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 and high blood pressure are major risk factors for heart disease. Being overweight, obese, or physically inactive 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 to lớn 4 times greater than a nonsmoker"s. And if you smoke around loved ones, you"re increasing their risk with secondhand 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 quit. Within 24 hours of quitting, your heart attaông xã risk begins lớn fall.
Life after a heart attack
It is possible lớn regain your health after a heart attaông xã. By avoiding cigarettes, becoming more active sầu, và watching what you eat, you can give your heart & overall health a big boost. One of the best ways to lớn learn how lớn make these changes is lớn take part in a cardiac rehab program. Ask your doctor for recommendations.

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