This case-report emphasizes an uncommon cause of hypertension in an adolescent: reflux nephropathy. Reflux nephropathy is a frequent hypertension and renal failure etiology. Medical treatment is unknown from cardiologist. [Copyright &y& Elsevier]

Abstract: It is rare to observe right ventricular infarction caused by isolated right ventricular branch occlusion. Isolated right ventricular infarction accounts for less than three percent of all cases of infarction. Generally, it is associated with occlusion of a non dominant right coronary artery or of a right ventricular branch. ECG can be misleading with ST segment elevation in anterior leads. We describe a patient admitted for chest pain with ST segment elevation in leads V1 to V3 associated with ST segment elevation in leads V3R and V4R. Coronary angiography demonstrated isolated total occlusion of the right ventricular branch. Thus, right precordial leads need to be done in every patient presenting with ST segment elevation in precordial leads V1 to V3 and not only in inferior myocardial infarction.

Abstract: The occurrence of an acute myocardial infarction (MI) after chest trauma is a rare complication. We report a case of a 58-year-old man presenting with an acute anterolateral MI secondary to blunt chest trauma. Coronary angiography revealed a non significant lesion of a first diagonal branch without any atherosclerosis lesion on coronary artery. He was conservatively managed and resulted in a good prognosis. Based on this case, we discuss the path physiologic mechanism of MI following chest trauma. [Copyright &y& Elsevier]

Abstract: Cardiac troponin I (TnIC) is a sensitive and specific marker for myocardial injuries. A part from its diagnosis character, troponin is a major element for mid term prognosis with regard to occurred cardiovascular events. We are reporting the case of a 56-year-old man admitted to hospital for an inaugural myocardial infarction with positive evolution despite a very high level of troponin (1200 ng/ml) in post re-vascularisation. The context of moderate risk factors and the early re-vascularisation probably contributed to a favourable evolution of the patient. A very high troponin value seems to be more in favour of an effective re-perfusion rather than a mid term prognosis factor in this case. [Copyright &y& Elsevier]
