Description

Cardiac ischemia, often referred to as myocardial ischemia, is a condition characterized by reduced blood flow to the heart muscle, leading to inadequate oxygen supply. This insufficient oxygenation can result in chest pain or discomfort, known as angina, and if left untreated, it may progress to more severe conditions such as heart attack or myocardial infarction. Cardiac ischemia typically occurs due to atherosclerosis, a condition where plaque builds up inside the coronary arteries, narrowing them and restricting blood flow to the heart muscle. Elevated levels of Low-Density Lipoprotein (LDL) cholesterol in the bloodstream can lead to the deposition of plaque in the coronary arteries, gradually reducing blood flow. High blood pressure puts added strain on the heart and arteries, increasing the risk of arterial damage and atherosclerosis. Tobacco smoke contains many harmful chemicals that can damage the blood vessels, promoting the development of atherosclerosis and accelerating the progression of cardiac ischemia. Uncontrolled diabetes can damage blood vessels throughout the body, including the coronary arteries, contributing to atherosclerosis and ischemic heart disease. Excess body weight and obesity are associated with various risk factors for cardiac ischemia, including hypertension, high cholesterol, and diabetes. Lack of regular physical activity is linked to an increased risk of obesity, high blood pressure, and abnormal lipid levels, all of which are risk factors for cardiac ischemia. Individuals with a family history of heart disease or cardiac events are at a higher risk of developing cardiac ischemia themselves.

The risk of cardiac ischemia increases with age, as the arteries tend to become narrower and less flexible over time. The symptoms of cardiac ischemia can vary depending on the severity and duration of reduced blood flow to the heart muscle. The most typical symptom of cardiac ischemia is chest pain or discomfort, often described as tightness, pressure, squeezing, or aching. This pain may radiate to the arms, neck, jaw, back, or abdomen. Reduced blood flow to the heart can impair its ability to pump effectively, leading to shortness of breath, especially during physical exertion or emotional stress. Cardiac ischemia can cause fatigue and weakness due to the heart muscle not receiving an adequate supply of oxygen-rich blood. Some individuals may experience nausea, light-headedness, or dizziness, particularly when exerting themselves or during episodes of chest pain. Arrhythmias, or irregular heart rhythms, may accompany cardiac ischemia, leading to palpitations or a sensation of fluttering in the chest.

It is important to note that not everyone with cardiac ischemia experiences classic symptoms. Some individuals, particularly women and older adults, may have atypical symptoms or may even be asymptomatic, making diagnosis more challenging. Diagnosing cardiac ischemia typically involves a combination of medical history evaluation, physical examination, and diagnostic tests. An ECG records the electrical activity of the heart and can help identify abnormalities suggestive of ischemia, such as STsegment depression or elevation. During a stress test, the patient exercises on a treadmill or stationary bike while their heart rate, blood pressure, and ECG are monitored. This test can help detect abnormalities in heart function during physical exertion, indicating possible ischemia. An echocardiogram uses sound waves to create images of the heart's structure and function. It can reveal areas of reduced blood flow or impaired heart function due to ischemia. Coronary angiography involves injecting a contrast dye into the coronary arteries and taking Xray images (angiograms) to visualize any blockages or narrowing in the arteries.

In addition to these tests, blood tests may be performed to measure levels of cardiac biomarkers such as troponin, which can indicate damage to the heart muscle associated with ischemia or heart attack. The treatment approach for cardiac ischemia aims to relieve symptoms, improve blood flow to the heart, prevent complications, and reduce the risk of future cardiac events. Nitroglycerin is commonly used to relieve chest pain associated with cardiac ischemia by dilating the coronary arteries and improving blood flow to the heart. Medications such as aspirin or clopidogrel may be prescribed to reduce the risk of blood clots forming in the coronary arteries. Betablockers help lower blood pressure, reduce heart rate, and decrease the workload on the heart, thereby reducing the risk of ischemia and improving symptoms. Maintaining a healthy weight through diet and exercise can help reduce the strain on the heart and lower the risk of cardiac ischemia. In cases where multiple coronary arteries are severely blocked, bypass surgery may be recommended. This procedure involves rerouting blood flow around the blocked arteries using blood vessels harvested from other parts of the body.

Cardiac rehabilitation programs often include supervised exercise training tailored to individual needs and fitness levels, helping patients regain strength and confidence in their physical abilities. Patients receive education and counselling on topics such as heart-healthy lifestyle choices, medication management, stress reduction techniques, and coping strategies for managing cardiac symptoms and anxiety. It is essential for individuals at risk of cardiac ischemia to adopt a heart-healthy lifestyle, adhere to prescribed medications, and undergo regular medical monitoring to optimize their heart health and overall well-being.
