Sharma H, Radhakrishnan A, Nightingale P, et al. - Mitral regurgitation (MR) following acute myocardial infarction (AMI) developed in over one-quarter of patients and was related to lower survival, even when mild. MI subtype did not impact prevalence as well as severity of MR, however, delayed revascularization post-non-ST elevation myocardial infarction more commonly led to MR development.

• A total of 1000 patients admitted with AMI in 2016/17 managed by percutaneous coronary intervention were included.

• Presence of MR was detected in 294 of 1000 (29%) cases.

• Older age, worse left ventricular ejection fraction (LVEF) and creatinine clearance, and higher rates of hypertension, heart failure, previous MI and severe flow-limitation in the circumflex or right coronary artery were noted in MR cases vs patients without MR.

• Deaths of 56 of 288 (19%) patients with untreated MR were recorded following a mean of 3.2 years.

• Age and LVEF were revealed as independent predictors of mortality.
