A normal ECG does not rule out acute myocardial infarction. Mistakes in interpretation are relatively common, and the failure to identify high risk features has a negative effect on the quality of patient care. [12] It should be determined if a person is at high risk for myocardial infarction before conducting imaging tests to make a diagnosis ...
Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
Information card published by the National Heart, Lung, and Blood Institute urging people with symptoms of angina to call the emergency medical services.. Because of the relationship between the duration of myocardial ischemia and the extent of damage to heart muscle, public health services encourage people experiencing possible acute coronary syndrome symptoms or those around them to ...
Acute coronary syndrome (ACS) is a syndrome due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [1] The most common symptom is centrally located pressure-like chest pain, often radiating to the left shoulder [2] or angle of the jaw, and associated with nausea and sweating.
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress .
Thrombosis, transient ischemic attack, acute coronary syndrome, Budd-Chiari syndrome. [1] Causes: Overproduction of hematopoietic cells, genetic mutations. [1] Diagnostic method: Clinical criteria. Differential diagnosis: Chronic myelogenous leukemia, myelodysplastic syndrome, polycythemia vera, primary myelofibrosis, secondary thrombocytosis ...
With angiography and improved recognition of the condition, diagnosis of SCAD has improved since the early 2010s. While prior studies had reported a SCAD prevalence of less than 1% in patients presenting with acute coronary syndrome, more recent data suggests the prevalence of SCAD in acute coronary syndrome patients may be between 2-4%. [28]
The main cause of angina is coronary artery disease, but can result from other non-atherosclerotic causes such as anemia and heart failure. Stable angina results if the angina resolves with rest or nitroglycerin, but can progress to unstable angina which is a form of acute coronary syndrome.
