Fragmented QRS (fQRS) results from myocardial scarring and predicts cardiovascular mortality and ventricular arrhythmia. In this retrospective cohort study, we evaluated the prevalence and prognostic value of fQRS in patients hospitalized for heart failure between 1st January 2010 and 31st December 2016 at a tertiary center in Hong Kong. We found fQRS to be an independent predictor of adverse clinical outcomes, with higher risks in those with higher fQRS burden.

Heart failure (HF) is the major mechanism of mortality in acute myocardial infarction (AMI) during early or intermediate post-AMI period. But heart failure is one of the most common long-term complications of AMI. Applied the retrospective cohort study design with nation representative population data, this study traced the incidence of late-onset heart failure since 1 year after newly developed acute myocardial infarction and assessed its risk factors. Methods and Results: Using the Korea National Health Insurance database, 18,328 newly developed AMI patients aged 40 years or older and first hospitalized in 2010 for 3 days or more, were set up as baseline cohort (12,403). The incidence rate of AMI per 100,000 persons was 79.8 overall, and 49.6 for women and 112.3 for men. A total of 2010 (1073 men, 937 women) were newly developed with HF during 6 years following post AMI. Cumulative incidences of HF per 1000 AMI patients for a year at each time period were 37.4 in initial hospitalization, 32.3 in 1 year after discharge, and 8.9 in 1–6 years. The overall and age-specific incidence rates of HF were higher in women than men. For late-onset HF, female, medical aid, pre-existing hypertension, severity of AMI, duration of hospital stay during index admission, reperfusion treatment, and drug prescription pattern including diuretics, affected the occurrence of late-onset HF. Conclusion: With respect to late-onset HF following AMI, appropriate management including hypertension and medical aid program in addition to quality improvement of AMI treatment are required to reduce the risk of late-onset heart failure.

BackgroundOlder adults living with heart failure (HF) in long-term care (LTC) experience frequent hospitalization. Using routinely available clinical information, we examined resident-level factors that precipitate hospitalization within 90 days of admission to LTC.MethodsThis was a retrospective cohort study of older adults diagnosed with HF, who were admitted to LTC in Ontario, Canada, between 2011 and 2013. Multivariate logistic regression models using generalized estimating equations were developed to determine predictors of hospitalization in residents with HF.ResultsEntry to LTC from a hospital was the strongest predictor of future hospitalization (OR: 8.1, 95% CI: 7.1–9.3), followed by a score of three or greater on the Changes in Health, End-stage Signs and Symptoms scale, a measure of moderate to severe medical instability (O.R 4.2, 95% CI: 3.1–5.9). Other variables that increased the likelihood of hospitalization included being flagged as a high risk for falls, two or more physician visits, and increased monitoring for acute medical illness within 14 days of admission. ConclusionOur findings highlight that health instability and transitions from acute to LTC will increase the likelihood of transitioning back into the hospital setting. The identified predisposing factors suggest the need for targeted prevention strategies for those in high-risk groups.

Abstract Background: Even though great advances have been made in the treatment of coronary artery disease (CAD) owing to coronary revascularization and modern antiremodeling therapy, it remains the major cause of cardiac morbidity and mortality worldwide. Risk stratification in CAD patients is primarily based on left ventricular ejection fraction (LVEF), risk scores, and some serum markers. The value of baseline Left ventricular fractional shortening (LVFS) level in predicting the clinical outcomes has not yet been determined.Methods: In this retrospective cohort study, a total of 3561 patients were enrolled in Clinical Outcomes and Risk Factors of Patients with CAD after percutaneous coronary intervention (PCI), from January 2013 to December 2017. After excluding patients without echocardiography data, we finally enrolled 2787 patients. These patients were divided into two groups according to LVFS value. The lower group (LVFS <31%, n=741), the higher group (LVFS≥31%, n=2046). The average follow-up time were 37.59±22.24 months.Results: We found that there were significant differences between the two groups in the incidence of all-cause mortality (ACM) (P<0.001), cardiac mortality (CM) (P<0.001), major adverse cardiovascular events (MACEs) (P<0.05) and major adverse cardiovascular and cerebrovascular events (MACCEs) (P<0.05). Multivariate Cox regression analyses showed that LVFS was an independent predictor for ACM (hazard ratio [HR]:0.473 [95% confidence interval [CI]:0.290-0.772],P=0.003), CM (HR: 0.393 [95% CI:0.213-0.725],P=0.003) in acute coronary syndrome (ACS) patients but that it was an independent predictor for only the incidence of CM (HR: 0.153 [95% CI:0.046-0.504],P=0.002) in stable CAD patients.Conclusion This study indicates that baseline LVFS is an independent and novel predictor of adverse long-term outcomes in CAD patients who underwent PCI.
