Myocardial inferior infarction with mechanical rivascularization and implant of drug eluting stent on right coronary artery in 2012. Residual ejection fraction of 47% with inferior hypocinesia. Pacemaker DDD implant for 2nd degree atrioventricular block in 2013. Atrial fibrillation from July 2021. Acute nocturnal heart failure with hypoxiemia (PO2 76%) and necessity of non invasive ventilation in November 2021 without worsening of coronary tree at coronarography and echocardiografic finding of EF 47% with inferior and posterior hypocinesia. Troponin I hs 53.6 pg/ml BNP 378 ng/ml. None relevant arrhytmias at pacemaker control.
