Comprehensive guide to PPD skin test interpretation, tuberculosis screening, and risk assessment. Learn about positive PPD reactions, measurement techniques, clinical significance, and follow-up procedures.
Myocardial infarction, commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is severely reduced or blocked, leading to tissue damage. This article provides a comprehensive overview of how plaque buildup and blood clots in the coronary arteries trigger a heart attack. Understand the critical role of coronary arteries, the impact of blockages, and the consequences for heart muscle health.
Atherosclerosis is a prevalent cardiovascular disease where plaque accumulates within artery walls, leading to narrowing and restricted blood flow. This article offers a detailed exploration of atherosclerosis, focusing on its development in the coronary arteries and its significant impact on heart health. Discover how plaque buildup can lead to a reduction in oxygen-rich blood supply, affecting the heart's vital function.
Atherosclerosis is a chronic inflammatory disease characterized by the progressive buildup of plaques within arterial walls, a process often initiated by endothelial dysfunction. This detailed article elucidates the intricate stages of atherosclerosis, tracing its development from initial, histologically subtle changes to advanced, complicated lesions that pose significant cardiovascular risks. Explore the mechanisms, timeline, and clinical correlations of each stage in this pervasive disease.
Atherosclerosis is a progressive disease characterized by the buildup of plaques within artery walls, leading to significant cardiovascular complications. This detailed article explores the stages of atherosclerosis progression, from initial fatty streaks to advanced plaques, and delves into its severe late complications, including critical stenosis, superimposed thrombus, and aneurysm formation. Gain a deeper understanding of how this insidious condition impacts vascular health.
