A heart lesion is any stress or trauma delivered to the interior walls of the heart, resulting in tissue damage. This damage causes inflammation, which signals the body's immune response. These dangerous lesions are the forerunner of a disease known as atherosclerosis.Continue Reading
According to research at the National Institutes of Health, inflammation plays a key role in the development of plaque in the heart muscle. Inflammation causes monocytes, released during an immune response, to stick to the lesion. The accumulation of monocytes and other cells create a sticky plaque in the heart. As blood flows through the heart, substances such as fats, cholesterol and fibrin adhere to the plaque and cause the plaque to grow.
The growth of plaque causes arteries to narrow and harden. The resulting condition is atherosclerosis. Atherosclerosis limits the amount of blood that flows through the heart, which can lead to heart attack, stroke or other ailments. Atherosclerosis is also a major contributor to the death toll from cardiovascular disease, which claims over 600,000 lives every year, according to the Centers for Disease Control and Prevention. To minimize the risk of atherosclerosis, the CDC recommends smoking cessation, exercise and a diet low in cholesterol, salt and fat.Learn more about Cardiac Health
Calcium channel blockers help reduce blood pressure by preventing calcium from entering the muscle cells in the walls of the heart and blood vessels, which causes them to be relaxed, according to Mayo Clinic. Their relaxation means that the blood vessels are more open.Full Answer >
An irregular heart rate can be caused by a panic attack or by strong emotions, such as fear, stress or anxiety, according to WebMD. An irregular heartbeat can also be caused by intense exercise.Full Answer >
A cardiac stress test measures the blood flow to the heart while it is at rest and also during a period of stress, according to Mayo Clinic. A technician takes images of the heart at rest and again when it is working harder.Full Answer >
Diagnostic tests for heart conditions include electrocardiogram, stress test, echocardiogram, positron emission tomography scan and tilt table test options. Others include magnetic resonance imaging of the heart and cardiac CT scans, according to Johns Hopkins Medicine. These tests help determine and understand the complexity of a patient’s cardiovascular disease.Full Answer >
