Aims  Severe mitral regurgitation (MR) following acute myocardial infarction (MI) is associated with high mortality rates and has inconclusive recommendations in clinical guidelines. We aimed to report the international experience of patients with secondary MR following acute MI and compare the outcomes of those treated conservatively, surgically, and percutaneously. Methods and results  Retrospective international registry of consecutive patients with at least moderate-to-severe MR following MI treated in 21 centres in North America, Europe, and the Middle East. The registry included patients treated conservatively and those having surgical mitral valve repair or replacement (SMVR) or percutaneous mitral valve repair (PMVR) using edge-to-edge repair. The primary endpoint was in-hospital mortality. A total of 471 patients were included (43% female, age 73 ± 11 years): 205 underwent interventions, of whom 106 were SMVR and 99 PMVR. Patients who underwent mitral valve intervention were in a worse clinical state (Killip class ≥3 in 60% vs. 43%, P < 0.01), but yet had lower in-hospital and 1-year mortality compared with those treated conservatively [11% vs. 27%, P < 0.01 and 16% vs. 35%, P < 0.01; adjusted hazard ratio (HR) 0.28, 95% confidence interval (CI) 0.18–0.46, P < 0.01]. Surgical mitral valve repair or replacement was performed earlier than PMVR [median of 12 days from MI date (interquartile range 5–19) vs. 19 days (10–40), P < 0.01]. The immediate procedural success did not differ between SMVR and PMVR (92% vs. 93%, P = 0.53). However, in-hospital and 1-year mortality rates were significantly higher in SMVR than in PMVR (16% vs. 6%, P = 0.03 and 31% vs. 17%, P = 0.04; adjusted HR 3.75, 95% CI 1.55–9.07, P < 0.01). Conclusions  Early intervention may mitigate the poor prognosis associated with conservative therapy in patients with post-MI MR. Percutaneous mitral valve repair can serve as an alternative for surgery in reducing MR for high-risk patients.

Within our cohort, PARIS and PRECISE-DAPT were fairly to moderately effective for the prediction of bleeding. Their predictiveness varies according to the bleeding severity. PARIS-derived bleeding risk assessment was associated with a higher net benefit compared to PRECISE-DAPT-based bleeding risk assessment.

Aims Nutrition is an important determinant of health above the age of 80 years. Malnutrition in the elderly is often underdiagnosed. The aim of this study was to report the prevalence and prognostic value of malnutrition in patients ≥80 years old with atrial fibrillation (AF) with and without anticoagulant therapy. Methods and results We assessed the nutritional status of 4724 octogenarian patients with diagnoses of AF in a single centre from Spain between 2014 and 2017 with the CONUT score. Malnutrition was confirmed in 2036 patients (43.1%). Anticoagulation prescription was more frequent in patients with good nutrition than in those malnourished (79.5% vs. 71.7%, P < 0.001). The impact of malnutrition on mortality was evaluated by Cox regression, whereas its association with ischaemic stroke and major bleeding was studied through competing risk analysis. After multivariate adjusting, malnutrition was associated with mortality [hazard ratio (HR) 1.36, 95% confidence interval (CI) 1.24–1.49], stroke [sub-distribution HR (sHR) 1.37, 95% CI 1.10–1.69], and major bleeding (sHR 1.29, 95% CI 1.02–1.64). In anticoagulated patients, the embolic–haemorrhagic trade-off event was virtually neutral for those who had normal nutritional status [average daily rates (ADRs) for stroke and bleeding: 4.70 and 4.69 per 100 000 patients/day, respectively; difference = +0.01 per 100 000 patients/day; P = 0.99] and negative for those with malnutrition (ADR for stroke and bleeding: 5.38 and 7.61 per 100 000 patients/day, respectively; difference = −2.23 per 100 000 patients/day; P = 0.07). Conclusion Malnutrition is very common in octogenarian patients with AF, being a clinical predictor for poor prognosis. For anticoagulated patients, malnutrition was associated with a negative embolic–haemorrhagic balance.
