clove and Acute-Coronary-Syndrome

Chest pain is one of the different elements of orientation for the diagnosis of acute coronary syndrome. Sometimes its clinical presentation is misleading. The objective of this study was to describe the characteristics of chest pain during an acute coronary syndrome in the cardiology department of the Joseph Raseta Befelatanana University Hospital Center, Antananarivo, Madagascar.. We carried out a cross-sectional, descriptive study of 10 months from January 2019 to October 2019. All patients diagnosed with acute coronary syndrome during this period were included.. Sixty-five cases were included. A "typical chest pain" was only encountered in 7.7% of cases. Advanced age (p = 0.04) and sedentary lifestyle (p = 0.03) were associated with the occurrence of silent myocardial ischemia, and. hypertension with a prolonged duration (≥15 minutes) of chest pain (p = 0.03). Dyslipidemia was associated with atypical irradiation of chest pain (p = 0.003). Alcoholism had an impact on pain triggered by effort (p = 0.01) and relieved by rest (p = 0.04).. The current symptomatology of acute coronary syndrome is increasingly atypical. Knowledge of the factors that can influence the different characteristics of chest pain could serve as a benchmark in clinical practice in our population.

Cardiac troponin I (cTnI) is a sensitive and specific marker of acute coronary syndromes and myocardial damage. During the past few years, it has become the preferred biochemical marker of myocardial infarction. However, due to the sensitivity required for its detection, only automated systems can be used in developed countries. However, these are rather expensive and unaffordable for most laboratories in developing countries. Many manufacturers have therefore proposed rapid immunochromatographic tests to detect cTnI. The aim of this study was to assess the limit of detection (LOD) and performance of four rapid immunochromatographic tests available in Madagascar. The four tests evaluated were Hexagon Troponin, Nadal troponin I cassette, Troponitest+, and Amicheck-Trop. Amicheck-Trop had a sensitivity and negative predictive value of about 80%, whereas for the three others, they were about 20%. The specificity of Amicheck-Trop of 87.3% was lower than the specificities of the other tests (98% to 100%). These differences were explained by the limits of detection of the tests: 0.3 to 0.4 ng/ml for Amicheck-Trop but only 1.8 to 2 ng/ml for the three other tests. It was concluded that Amicheck-Trop could be useful in the management of acute myocardial infarction or myocarditis in sparsely equipped laboratories in developing countries.
