RESUMEN
BACKGROUND: We aimed to analyze the prevalence and long-term prognostic impact of non-cardiac comorbidities in patients with reduced and preserved left-ventricular ejection fraction (EF) following ST-elevation myocardial infarction (STEMI). METHOD: A total of 3033 STEMI patients undergoing primary percutaneous coronary intervention (pPCI) were divided in two groups: reduced EF < 50% and preserved EF ≥ 50%. The follow-up period was 8 years. RESULTS: Preserved EF was present in 1726 (55.4%) patients and reduced EF was present in 1389 (44.5%) patients. Non-cardiac comorbidities were more frequent in patients with reduced EF compared with patients with preserved EF (38.9% vs. 27.4%, respectively, p < 0.001). Lethal outcome was registered in 240 (17.2%) patients with reduced EF and in 40 (2.3%) patients with preserved EF, p < 0.001. Diabetes and chronic kidney disease (CKD) were independent predictors for 8-year mortality in patients with preserved EF. In patients with reduced EF, CKD was independently associated with 8-year mortality. CONCLUSION: In patients who had reduced EF, the prevalence of non-cardiac comorbidities was higher than in patients who had preserved EF after STEMI. Only diabetes mellitus and CKD were independently associated with 8-year mortality in analyzed patients.
RESUMEN
Background: Individual non-cardiac comorbidities are prevalent in HF; however, few studies reported how the aggregate burden of non-cardiac comorbidities affects long-term outcomes, and it is unknown whether this burden is associated with changes in health status. Aims: To assess the association of the overall burden of non-cardiac comorbidities with clinical outcomes and quality of life (QoL) in patients hospitalized for heart failure (HF). Methods: We prospectively enrolled patients hospitalized for HF from 52 hospitals in China. Eight key non-cardiac comorbidities [diabetes, chronic renal disease, chronic obstructive pulmonary disease (COPD), anemia, stroke, cancer, peripheral arterial disease (PAD), and liver cirrhosis] were included, and patients were categorized into four groups: none, one, two, and three or more comorbidities. We fitted Cox proportional hazards models to assess the burden of comorbidities on 1-year death and rehospitalization. Results: Of the 4,866 patients, 25.3% had no non-cardiac comorbidity, 32.2% had one, 22.9% had two, and 19.6% had three or more in China. Compared with those without non-cardiac comorbidities, patients with three or more comorbidities had higher risks of 1-year all-cause death [heart rate, HR 1.89; 95% confidence interval (CI) 1.48-2.39] and all-rehospitalization (HR 1.35; 95%CI 1.15-1.58) after adjustment. Although all patients with HF experienced a longitudinal improvement in QoL in the 180 days after discharge, those with three or more non-cardiac comorbidities had an unadjusted 11.4 (95%CI -13.4 to -9.4) lower Kansas City Cardiomyopathy Questionnaire (KCCQ) scores than patients without comorbidities. This difference decreased to -6.4 (95%CI -8.6 to -4.2) after adjustment for covariates. Conclusion: Among patients hospitalized with HF in this study, a higher burden of non-cardiac comorbidities was significantly associated with worse health-related QoL (HRQoL), increased risks of death, and rehospitalization post-discharge. The findings highlight the need to address the management of comorbidities effectively in standardized HF care.
RESUMEN
AIMS: To investigate the influence of non-cardiac comorbidities on outcomes of patients enrolled in the German transcatheter mitral valve interventions (TRAMI) registry. METHODS AND RESULTS: Intrahospital and 30-day MACCE rates (death of all causes, stroke and myocardial infarction) of 828 patients from the TRAMI registry were stratified by the number of non-cardiac comorbidities. The following non-cardiac comorbidities were prospectively recorded in the registry: diabetes, renal insufficiency, extracardiac arteriopathy, chronic lung disease, neurological disease or malignancy on palliative care. The 375 (45.3 %) patients with multiple (≥2) non-cardiac comorbidities presented with higher NYHA classes, higher logistic Euroscores, higher levels of NT-proBNP and a shorter 6-min walk distance. Rates of intraprocedural death (0.3 vs. 0.0 %, p = 0.41) and intrahospital MACCE (3.6 vs. 1.9 %, p = 0.16) were not significantly higher in patients with multiple non-cardiac comorbidities, but 30-day MACCE rate was significantly enhanced (6.4 vs. 3.6 %, p = 0.049). However, both patient groups showed a similar clinical improvement after 30 days. Renal insufficiency was the only non-cardiac comorbidity which was independently associated with the 30-day MACCE rate. CONCLUSIONS: MitraClip device placement is feasible and safe in patients with multiple non-cardiac comorbidities resulting in a significant clinical improvement and acceptable intrahospital and 30-day event rates. Renal failure is an independent predictor of outcome.
