Major PVL without obvious infection occurs even 20 years after MVR with 10- and 20-year major PVL-free rates of 96.2% and 86.9%, respectively. Occurrence of major PVL after MVR is more frequent in elderly, male patients and those who undergo redo MVR.

Aims Dyslipidaemia is a modifiable cardiovascular risk factor with prognostic implications. Current strategies for lipid management in young adults are largely based on expert recommendations. We investigated the risks of death and cardiovascular disease in relation to each lipid component to establish evidence for primary prevention in young adults. Methods In this nationwide population-based cohort study, we analysed 5,688,055 statin-naïve subjects, aged 20–39 years, undergoing general health check-ups between 2009 and 2014. The endpoint was a composite of clinical events including death, myocardial infarction (MI), and stroke. We compared the incidence and risk of clinical events according to each lipid variable. Results During follow-up (median 7.1 years), clinical events occurred in 30,330 subjects (0.53%): 16,262 deaths (0.29%), 8578 MIs (0.15%), and 5967 strokes (0.10%). The risk of clinical events gradually increased with increasing total cholesterol (TC) and triglycerides and decreasing high-density lipoprotein cholesterol (HDL-C), largely driven by MI. Low-density lipoprotein cholesterol (LDL-C) had a J-shaped association with clinical events, showing the lowest risk for LDL-C of 84–101 mg/dL. Among lipid variables, triglycerides remained the sole independent predictor (adjusted hazard ratio, 1.20; p < 0.001) after adjusting for conventional risk factors. Conclusions For statin-naïve young adults, the risk of clinical events was proportional to lipid levels, positively with TC and triglycerides, negatively with HDL-C, and J-shaped with LDL-C. Triglycerides had an independent and the strongest association with the clinical events. Screening and intervention for abnormal lipid levels, particularly triglycerides, from an early age might be of clinical value.

Background Sodium-glucose co-transporter-2 inhibitors displayed cardiovascular benefits in type 2 diabetes mellitus in previous studies; however, there were some heterogeneities regarding respective cardiovascular outcomes within the class. Furthermore, their efficacies in Asians, females, and those with low cardiovascular risks were under-represented. Thus, we compared the cardiovascular outcomes between new users of dapagliflozin and empagliflozin in a broad range of patients with type 2 diabetes mellitus using a nationwide population-based real-world cohort from Korea. Methods Korean National Health Insurance registry data between May 2016 and December 2018 were extracted, and an active-comparator new-user design was applied. The primary outcome was a composite of heart failure (HF)-related events (i.e., hospitalization for HF and HF-related death), myocardial infarction, ischemic stroke, and cardiovascular death. The secondary outcomes were individual components of the primary outcome. Results A total of 366,031 new users of dapagliflozin or empagliflozin were identified. After 1:1 nearest-neighbor propensity score matching, 72,752 individuals (mean age approximately 56 years, 42% women) from each group were included in the final analysis, with a follow-up of 150,000 ~ person-years. Approximately 40% of the patients included in the study had type 2 diabetes mellitus as their sole cardiovascular risk factor, with no other risk factors. The risk of the primary outcome was not different significantly between dapagliflozin and empagliflozin users (hazard ratio [HR] 0.93, 95% confidence interval [CI] 0.855–1.006). The risks of secondary outcomes were also similar, with the exception of the risks of HF-related events (HR 0.84, 95% CI 0.714–0.989) and cardiovascular death (HR 0.76, 95% CI 0.618–0.921), which were significantly lower in the dapagliflozin users. Conclusions This large-scale nationwide population-based real-world cohort study revealed no significant difference in composite cardiovascular outcomes between new users of dapagliflozin and empagliflozin. However, dapagliflozin might be associated with lower risks of hospitalization or death due to HF and cardiovascular death than empagliflozin in Asian patients with type 2 diabetes mellitus.

Background: Dyslipidemia is a modifiable cardiovascular risk factor with prognostic implications. Current strategies for lipid management in young adults are largely based on expert recommendations. We sought to investigate the risk of death and cardiovascular disease in relation to lipid components to establish evidence for primary prevention in young adults. Methods: In a nationwide cohort using the National Health Insurance claims database, we analyzed 5,688,055 statin-naïve subjects, aged 20-39 years, undergoing health check-up between 2009 and 2014. The study endpoint was a composite of clinical events, including death, myocardial infarction (MI), and stroke. We compared the incidence and the risk of clinical events according to lipid variables, including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides. Results: During follow-up (median 7.1 years), clinical events occurred in 30,330 subjects (0.53%); 16,262 deaths (0.29%), 8,578 MIs (0.15%), and 5,967 strokes (0.10%). The risk of clinical events gradually increased with increasing TC and triglycerides, and decreasing HDL-C, with a great contribution by MI. LDL-C had a J-shaped association with the study endpoint, showing the lowest risk in LDL-C of 84-101 mg/dL. Among lipid variables, triglycerides remained the sole independent predictor (adjusted HR 1.20, p <0.001), after adjusting for conventional risk factors. Conclusions: In ‘statin-naïve’ young adults aged 20-39 years, the risk of clinical events was proportional to lipid levels; positively with TC and triglycerides, negatively with HDL-C, and J-shaped with LDL-C. Triglycerides had the strongest and independent association with clinical events. Screening and intervention of abnormal lipid levels, particularly triglycerides, from an early age might be required.
