Prognoses in STEMI and NSTEMI beyond one year from onset remain unclear. We aimed to compare the treatments and the two-year outcomes in patients with myocardial infarction (MI) enrolled at the Polish Registry of Acute Coronary Syndromes (PL-ACS). ⋯ The unadjusted long-term prognosis was worse in NSTEMI. After adjustment for the baseline characteristics and treatment strategy, the long-term prognosis was worse in STEMI. Patients with MI treated invasively showed more favorable clinical characteristics and received guideline-recommended therapy more often than patients who did not undergo invasive treatment.

Chronic severe pulmonary regurgitation (PR) causes progressive right ventricular (RV) dysfunction and heart failure. Parameters defining the optimal time point for surgery of chronic PR are lacking. The present study prospectively evaluated the impact of preoperative clinical parameters, cardiorespiratory function, QRS duration and NT-proBNP levels on post operative RV function and volumes assessed by cardiac magnetic resonance imaging (CMR) in patients with chronic severe PR undergoing pulmonary valve replacement. ⋯ Valve replacement in severe pulmonary regurgitation causes significant reduction of RV volumes. Both, preoperative NT-proBNP level elevation and QRS prolongation indicate patients with poorer outcome regarding RV function and volumes.

Review Meta Analysis Comparative Study
Hypothermia after cardiac arrest should be further evaluated--a systematic review of randomised trials with meta-analysis and trial sequential analysis.
Guidelines recommend mild induced hypothermia (MIH) to reduce mortality and neurological impairment after out-of-hospital cardiac arrest. Our objective was to systematically evaluate the evidence for MIH taking into consideration the risks of systematic and random error and to GRADE the evidence. ⋯ Evidence regarding MIH after out-of-hospital cardiac arrest is still inconclusive and associated with non-negligible risks of systematic and random errors. Using GRADE-methodology, we conclude that the quality of evidence is low. Our findings demonstrate that clinical equipoise exists and that large well-designed randomised trials with low risk of bias are needed.

Prediction of complications in pregnant women with cardiac diseases referred to a tertiary center.
Prediction of adverse maternal and neonatal events in women with heart disease is not well established. We aimed to assess cardiac, obstetrical and neonatal complications in pregnant women with heart disease referred to our tertiary care center and validate a previously proposed risk index. ⋯ The CARPREG risk index has a high sensitivity and negative predictive value with regards to cardiac complications in pregnant women with heart disease. It may, therefore, be routinely used to improve the assessment of cardiac risk before and during pregnancy.
