Silent myocardial ischemia is a condition of reduced oxygen-rich blood flow to the heart that occurs in the absence of chest discomfort or other symptoms of angina, e.g., dyspnea, nausea, diaphoresis, etc.
If ischemia is severe or lasts too long, it can cause a heart attack (myocardial infarction) and can lead to heart tissue death. In most cases, a temporary blood shortage to the heart causes the pain of angina pectoris.
Some people who have myocardial ischemia don't have any signs or symptoms (silent ischemia). When they do occur, the most common is chest pressure or pain, typically on the left side of the body (angina pectoris).
Many people have ischemic episodes without knowing it or having pain — silent ischemia. They may have a heart attack with no warning. People with angina also may have undiagnosed episodes of silent ischemia.
Coronary heart disease (CHD) is when your coronary arteries become narrowed by a build-up of fatty material within their walls. These arteries supply your heart muscle with oxygen-rich blood. CHD is sometimes called ischaemic heart disease.
Men who have heart disease by age 50, can expect to live two years less than women who have heart disease, 21.3 years versus 23.3 years. Among people who have had a heart attack at a given age, life expectancy is strikingly similar for men and women.
Ischemic heart disease is one of the most frequent causes of heart failure and it is normally attributed to coronary artery disease, defined by the presence of one or more obstructive plaques, which determine a reduced coronary blood flow, causing myocardial ischemia and consequent heart failure.
Treatment / Management
Aspirin (antiplatelet therapy) and statin (lipid-lowering therapy) are also used. Psychotherapy: Mental stress can provoke silent ischemia; especially in patients with underlying coronary artery disease. Data suggests a possible benefit from behavioral stress reduction in such patients.
What are the common treatments for silent ischemia? Having a surgical procedure, such as: Balloon angioplasty. Coronary artery bypass graft (CABG)
Warning signs and symptoms of heart failure include shortness of breath, chronic coughing or wheezing, swelling, fatigue, loss of appetite, and others. Heart failure means the heart has failed to pump the way it should in order to circulate oxygen-rich blood throughout the body.
Diet. Follow a diet rich in fruits, vegetables, fish and white meat. As far as you can, minimise your consumption of pastries, cured meats, fried foods and red meats.
Of the body organs, the brain exhibits the highest sensitivity to ischemia.
Ischaemia with no obstructive coronary arteries (INOCA) is a common ischaemic heart disease with a female preponderance, mostly due to underlying coronary vascular dysfunction comprising coronary microvascular dysfunction and/or epicardial coronary vasospasm.
Abstract. The circadian pattern of numerous cardiovascular events (myocardial infarction, sudden cardiac death, stroke) reveals a peak in the early hours of the morning.
Ischemic cardiomyopathy symptoms may include: Shortness of breath. Swelling in your legs and feet (edema). Fatigue that makes you unable to exercise or carry out everyday activities.
Your emotions should go back to normal in two or three weeks. Some people find it helpful to join a support group where they can talk with others who've been through a similar experience.
Simple activities such as walking can be sufficient enough to get the blood flowing which can prevent escalating problems like critical limb Ischemia. As a recommendation, it's always best to speak with your doctor before you decide to embark on any change in your exercise routine.
If you experience pain and tightness in the chest in conjunction with palpitations, breathlessness, legs swelling or feeling faint, you should stop exercising immediately. Undergoing an exercise stress test (EST) can serve as an initial screening process for ischemic heart disease.
ECG manifestations of silent ischemia usually consist of the horizontal or downsloping ST segment depression recorded during an exercise test or during ambulatory ECG monitoring. Silent ST segment elevation may occur but is uncommon.
Foods that are high in soluble fiber and low in saturated and trans fats are excellent choices. Oats, nuts, beans, fatty fish, and olive and canola oils are all foods that are good for your heart.
Ischemic heart disease, also called coronary heart disease (CHD) or coronary artery disease, is the term given to heart problems caused by narrowed heart (coronary) arteries that supply blood to the heart muscle.
Ischemic heart disease refers to heart weakening caused by reduced blood flow to your heart. Typically, this reduced blood flow is the result of coronary artery disease, a condition that occurs when your coronary arteries narrow. Ischemic heart disease may also be called cardiac ischemia or ischemic cardiomyopathy.
The most common symptom of myocardial ischemia is angina (also called angina pectoris). This is chest pain (similar to indigestion or heartburn) that feels like: Chest discomfort. Heaviness.
