Rickettsial infection can affect multiple organs. Heart involvement is rare, although cases of acute myocarditis, pericarditis, advanced atrioventricular block have been reported. We report 2 cases of Rickettsia related to myocardial injury. The first case concerns a 65-year-old patient with minimal atherosclerotic risk factors, who had rickettsiosis one month before admission and who presents with silent myocardial ischemia revealed by a positive stress test, coronary angiogram showed a sub-occlusive stenosis of left anterior descending artery (LAD) with successful recanalization by implantation of one drug-eluting stent. The second one is 71-year-old patient treated for rickettsiosis. He was admitted to our department with Non-ST elevation myocardial infarction, coronary angiogram showed severe calcified triple vessel disease, he had a successful surgical revascularization.Through our observations, we will discuss the physio pathological mechanisms of coronary involvement by Rickettsiosis which would cause vasculopathy by endothelial cell damage.
