From clogged arteries to infections, heart disease covers a lot of ground. Oxygen-rich blood from your lungs flows to the left atrium, then to the left ventricle, which pumps it out to your body. Blood returns to the right atrium, then the right ventricle, which sends it back to your lungs for oxygen.
Four valves act like one-way doors to guide the blood through your heart. And round it goes -- unless you have heart disease. That limits the blood flow to your heart muscle. It also can affect how well your heart pumps and make the rest of your body short on oxygen, too.
If plaque breaks off and totally blocks an artery, you have a heart attack. Men CHD can affect women and men differently.
Men are more likely to have intense chest pain. This is what makes the lub-DUB sound of your heart. Three different problems can affect your heart valves: The valve lets blood go backward instead of forward.
The flaps get thick or stiff, or join together, and less blood gets through. Either way, they often get worse. The main symptom is a murmur -- a whooshing or swishing sound between heartbeats. Valve problems can make your heart work harder and cause blood flow problems, so you may: But more serious arrhythmia can keep your heart from doing its job the way it should and cause serious problems.
That means your organs and muscles may not get enough oxygen -- you could have chest pain and feel lightheaded, and you might even faint. If the rhythm gets totally out of whack, your heart gets like gelatin: This is called fibrillation, and it can be life-threatening.
The most common type is called dilated cardiomyopathy, and it happens in the left ventricle. That can cause problems like dizziness, fainting, and shortness of breath. Your kidneys may react to lower amounts of blood by holding on to more water and salt than usual, and that can lead to swelling in your legs, ankles, feet, and organs.
Sometimes, infections come on slowly; other times, quickly.Coronary artery disease, commonly known as heart disease, is a condition in which cholesterol, calcium, and other fats accumulate in the arteries that supply blood to the heart. This material hardens forming a plaque that blocks blood flow to the heart.
Coronary heart disease (CHD), also called coronary artery disease (CAD) and atherosclerotic heart disease, is the end result of the accumulation of atheromatous plaques within the walls of the.
Objective To undertake a systematic review and meta-analysis to assess the impact of cardiac rehabilitation (CR) on physical activity (PA) levels of patients with heart disease and the methodological quality of these studies.
When plaque builds up, it narrows your coronary arteries, decreasing blood flow to your heart. Eventually, the decreased blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms.
