2 dni temu · A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]
16 lip 2024 · The working diagnosis Myocardial Infarction with Nonobstructive Coronary Arteries (MINOCA) is being increasingly recognized with the common use of high-sensitivity troponins and coronary angiography, accounting for 5% to 10% of all acute myocardial infarction presentations.
21 lip 2024 · This clinical consensus statement outlines the diagnosis, haemodynamic consequences, and treatment strategies of VSDs complicating AMI, with a focus on current available evidence and on major research questions to fill the gap in evidence.
4 dni temu · Myocardial infarction(MI) ECG patterns in infarction. A zone of ischemia typically produces ST segment depression. A zone of injury produces ST segment elevation. A zone of infarction produces a large Q wave in the QRS complex. Genesis of the Q wave in infarction. The normal situation
16 lip 2024 · This review aims to highlight differences and patterns in myocardial ischemia caused by epicardial obstructive CAD, coronary microvascular dysfunction (CMD) or vasomotor abnormalities and to elucidate the state of the art in correctly diagnosing these different patterns.
17 lip 2024 · Cardiac magnetic resonance (CMR) is the imaging gold standard for cardiac structure, function, and myocardial tissue characterization; 12 CMR can distinguish MI from nonischemic causes of acute myocardial injury, and accurately determine the territory of acute infarction and its extent.
23 lip 2024 · After IWMI, ST↑ in leads II, III, and aVF is the key to diagnosing myocardial injury affecting the inferior and posterior walls of the heart.
