Cocaine-induced acute myocardial infarction.
Acute myocardial infarction may occur following cocaine use. Cocaine-induced infarction is particularly common in younger patients aged 18 to 45 years old. Patients may or may not have angiographic evidence of coronary artery disease at the time of their acute event. Previous studies have shown that coronary artery spasm occurs with cocaine use, and perhaps platelet activation, both contributin...
متن کاملPathophysiological role of neutrophils in acute myocardial infarction.
The pathogenesis of acute myocardial infarction is known to be mediated by systemic, intraplaque and myocardial inflammatory processes. Among different immune cell subsets, compelling evidence now indicates a pivotal role for neutrophils in acute coronary syndromes. Neutrophils infiltrate coronary plaques and the infarcted myocardium and mediate tissue damage by releasing matrix-degrading enzym...
متن کاملRapid Diagnosis of Acute Myocardial Infarction
To improve the specificity of biochemical markers of myocardial infarction (MI) a method to measure cardiac troponin-I (CTn-I) was developed. CTn-I is a protein unique to cardiac muscle and is released after MI. Consecutive 150 patients admitted to the coronary care unit was studied. Value of CTn-I was determined in all samples. CTn-I concentration in the MI patients group was increased com...
متن کاملCocaine-associated chest pain and acute myocardial infarction.
The use of cocaine, either intranasal or inhaled, is an increasingly significant public health issue in the United States and Europe. Cocaine is the second most commonly used illicit drug (second to marijuana) 1 in the United States in 2005 there were approximately 450 000 cocaine-related encounters in Emergency Departments. 2 The World Drug Report of 2009 estimates that in individuals between ...
متن کاملCocaine induced myocardial infarction.
The case of a 29 year old man who presented with chest pains after the use of cocaine is reported. The diagnosis of myocardial infarction was made on the electrocardiogram changes and lactate dehydrogenase profile. The diagnosis may be overlooked if there is no direct questioning about the use of drugs such as cocaine. Diazepam has an important role in the management of cardiac complications af...
