Although older adults are the fastest-growing age group among cardiovascular patients, nonagenarians with ST-segment elevation myocardial infarction (STEMI) are under-represented in clinical trials. The aims of this study are to analyze the clinical presentation and outcomes of nonagenarian patients presenting with STEMI and to compare in-hospital and 1-year clinical outcomes between those treated with optimal medical treatment alone and those receiving primary percutaneous coronary intervention (pPCI). We included all consecutive nonagenarians presenting with STEMI admitted in 2 academic centers between 2006 and 2018. There were no exclusion criteria. All-cause mortality was assessed in-hospital and at 1-year follow-up. In total, 167 patients (mean age 91.9 ± 0.17 years; 60% females) were included. Emergent catheterization was performed in 60% of our patients, and pPCI was performed in 50% (n = 83). Overall mortality was 22% in-hospital and 41% at 1-year follow-up. The pPCI group had lower mortality than the medical treatment group: 12% versus 32% in-hospital (p <0.01) and 26% versus 45% at 1-year follow-up (p <0.01), respectively. Multivariable analysis identified 4 independent predictors of all-cause mortality at 1 year: mechanical complications (adjusted odds ratio [OR] 9.25, p <0.01), Killip class III/IV (adjusted OR 4.22, p <0.01), serum creatinine at admission (mg/dl; adjusted OR 1.8, p <0.01), and pPCI (adjusted OR 0.52; p <0.05). In conclusion, STEMI in nonagenarians is becoming increasingly common. pPCI may be the preferred strategy in this high-risk cohort when a high grade of disability is not present. Hemodynamic compromise, the presence of complications related to myocardial infarction, renal impairment, and early revascularization may be related to prognosis in these patients.

BACKGROUND: The evidence about the effectiveness and safety of oral anticoagulation in patients on hemodialysis is conflicting and scarce. Percutaneous left atrial appendage occlusion (LAAO) has demonstrated to be a valid alternative therapeutic option for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). The aim of this study is to present the outcomes of percutaneous LAAO in patients with end-stage renal disease (ESRD) on hemodialysis and NVAF in our center. METHODS: Retrospective chart review of clinical records, demographics, LAAO procedure, complications and outcomes of patients with NVAF and ESRD on hemodialysis who underwent a percutaneous LAAO in our center between January 2017 and January 2019. RESULTS: In the period of the study, eight patients with ESRD on hemodialysis underwent a percutaneous LAAO in our center. The overall mean age was 67.5 years (range 56-81; SD ± 7.2). All patients had permanent NVAF. The total mean dialysis duration was 8.49 years (range 0.83-14.8; SD ± 6.2). The mean CHA2DS2-VASc and HAS-BLED scores were high [4.75 (SD ± 1.16) and 4.62 (SD ± 0.91), respectively]. All patients had history of a major hemorrhagic event (BARC Score ≥3). Most patients (n=6) showed left ventricular hypertrophy, and the average LVEF was 54% (SD ± 6.5). All devices were implanted successfully. Post-procedural antithrombotic regimen prescribed was based on antiplatelet therapy. No deaths, cardioembolic events, or major bleeding (according to the BARC scale) were reported during a mean follow-up of 14.24 months (SD ± 9.44). CONCLUSION: Percutaneous LAAO could be of particularly interest in patients with NVAF and CKD in hemodialysis. Further studies will be necessary to confirm this hypothesis.

Background: Spontaneous coronary artery dissection (SCAD) is an infrequent and often misdiagnosis of a non-atherosclerotic cause of acute coronary syndrome (ACS). It is an important cause of ACS in young women, responsible for up to 25% of all cases in women <50 years of age without cardiovascular risk factors. Clinical presentation ranges from ST-segment-elevation myocardial infarction (MI) to ventricular fibrillation and sudden death. The treatment of patients with SCAD is a challenge and the ideal management strategy has yet to be determined. Case summary: A 42-year-old woman without family history of cardiac disease and neither traditional atherosclerotic risk factors presented to our centre with an anterior acute ST-segment-elevation MI secondary to multiple spontaneous dissections of the left main, anterior descending, and ramus intermedius coronary arteries. Stenting was performed in the left anterior descending coronary artery and left main coronary artery to resolve its occlusion. Fibromuscular dysplasia was confirmed via computed tomography angiography. Discussion: More cases are now being identified of SCAD due to increased clinical index of suspicion, earlier use of invasive angiography, and intracoronary imaging in patients presenting with acute chest pain. Despite this, the absence of previous cardiovascular risk factors and the ignorance of this pathology delay the start of an adequate medical treatment and the performance of a cardiac catheterization. Prognostic data are limited, partly because of its underdiagnosis and lack of prospective studies, so its knowledge is necessary to improve the prognosis of these patients.

BACKGROUND: Renal replacement therapy (RRT) after heart transplant (HT) is associated with worse prognosis. We aimed to identify predictors of RRT and the impact of this complication on long-term survival. METHODS: Cohort study of HT patients. Univariate and multivariate competing-risk regression was performed to identify independent predictors of RRT. The cumulative incidence function was plotted for RRT. The Kaplan-Meier method was used to compare long-term survival. RESULTS: We included 103 patients. At multivariate analysis, only the emergency status of HT (short-term mechanical circulatory support as a bridge to transplant), chronic kidney disease, and low oxygen delivery were independent predictors of RRT (subhazard ratio [SHR] 4.11, 95% CI 1.84-9.14; SHR 3.17, 95% CI 1.29-7.77; SHR 2.86, 95% CI 1.14-7.19, respectively). Elective HT patients that required RRT showed a significantly reduced survival comparable to patients with emergency HT and RRT (75% ± 13% vs. 67% ± 16%). The absence of RRT implied an excellent survival in patients with an emergency status of HT and elective HT (100% vs. 93% ± 4%). CONCLUSION: The emergency status of HT, chronic kidney disease, and low oxygen delivery were independent predictors of RRT. The occurrence of RRT increases the risk of death in elective HT as much as in patients with an emergency status.
