RESUMEN
PURPOSE OF THE REVIEW: Multimorbidity, the presence of two or more comorbidities, is common in patients with heart failure (HF) and worsens clinical outcomes. In Asia, multimorbidity has become the norm rather than the exception. Therefore, we evaluated the burden and unique patterns of comorbidities in Asian patients with HF. RECENT FINDINGS: Asian patients with HF are almost a decade younger than Western Europe and North American patients. However, over two in three patients have multimorbidity. Comorbidities usually cluster due to the close and complex links between chronic medical conditions. Elucidating these links may guide public health policies to address risk factors. In Asia, barriers in treating comorbidities at the patient, healthcare system and national level hamper preventative efforts. Asian patients with HF are younger yet have a higher burden of comorbidities than Western patients. A better understanding of the unique co-occurrence of medical conditions in Asia can improve the prevention and treatment of HF.

Heart failure (HF) is a well-described final common pathway for a broad range of diseases however substantial confusion exists regarding how to describe, study, and track these underlying etiologic conditions. We describe (1) the overlap in HF etiologies, comorbidities, and case definitions as currently used in HF registries led or managed by members of the global HF roundtable; (2) strategies to improve the quality of evidence on etiologies and modifiable risk factors of HF in registries; and (3) opportunities to use clinical HF registries as a platform for public health surveillance, implementation research, and randomized registry trials to reduce the global burden of noncommunicable diseases. Investment and collaboration among countries to improve the quality of evidence in global HF registries could contribute to achieving global health targets to reduce noncommunicable diseases and overall improvements in population health.

BACKGROUND: Insulin-treated patients with long duration of type 2 diabetes mellitus (T2DM) are at increased risk of ketoacidosis related to sodium-glucose co-transporter 2 inhibitor (SGLT2i). The extent of circulating ketone elevation in these patients remains unknown. We conducted this study to compare the serum ketone response between dapagliflozin, an SGLT2i, and sitagliptin, a dipeptidyl peptidase-4 inhibitor, among insulin-treated T2DM patients. METHODS: This was a randomized, open-label, active comparator-controlled study involving 60 insulin-treated T2DM patients. Participants were randomized 1:1 for 24-week of dapagliflozin 10 mg daily or sitagliptin 100 mg daily. Serum ß-hydroxybutyrate (BHB) levels were measured at baseline, 12 and 24 weeks after intervention. Comprehensive cardiometabolic assessments were performed with measurements of high-density lipoprotein cholesterol (HDL-C) cholesterol efflux capacity (CEC), vibration-controlled transient elastography and echocardiography. RESULTS: Among these 60 insulin-treated participants (mean age 58.8 years, diabetes duration 18.2 years, glycosylated hemoglobin 8.87%), as compared with sitagliptin, serum BHB levels increased significantly after 24 weeks of dapagliflozin (P=0.045), with a median of 27% increase from baseline. Change in serum BHB levels correlated significantly with change in free fatty acid levels. Despite similar glucose lowering, dapagliflozin led to significant improvements in body weight (P=0.006), waist circumference (P=0.028), HDL-C (P=0.041), CEC (P=0.045), controlled attenuation parameter (P=0.007), and liver stiffness (P=0.022). Average E/e', an echocardiographic index of left ventricular diastolic dysfunction, was also significantly lower at 24 weeks in participants treated with dapagliflozin (P=0.037). CONCLUSION: Among insulin-treated T2DM patients with long diabetes duration, compared to sitagliptin, dapagliflozin modestly increased ketone levels and was associated with cardiometabolic benefits.

Cardiac troponin is a sensitive and specific biomarker for acute myocardial injury and has been used in the diagnosis of acute coronary syndromes, and has emerged as a tool for identifying high risk individuals for primary preventive therapy. Recent evidence has emerged indicating that high-sensitivity cardiac troponin assays, which allow robust detection of very low troponin concentrations, could detect subclinical injury in asymptomatic patients. On 24 March 2018, a group of cardiologists from the Asia Pacific region convened to review the data and discuss the potential utility of high-sensitivity troponin I (hsTnI) in the risk assessment of cardiovascular disease in the general population. The group recognized the immense burden of cardiovascular disease in the Asia-Pacific region, and the limitations of current risk stratification strategies. Data demonstrates that cardiac biomarkers like hsTnI could improve risk stratification, and thresholds for hsTnI in cardiovascular disease risk classification have been developed in Caucasian populations but not validated in Asian populations. There is an urgent need to improve cardiovascular risk assessment in the Asia Pacific general population, validate the Asian threshold of high risk and prove the utility of targeting these high-risk individuals for primary preventive strategies.

BACKGROUND: Surgical ventricular restoration (SVR) improves left ventricular (LV) systolic function by partially restoring the normal geometry of the left ventricle. However, the beneficial effects of this surgical procedure on long-term clinical outcome remain controversial. The present study aimed to evaluate the independent determinants of 2-year morbidity and mortality rates after SVR. METHODS: Seventy-nine patients with ischemic heart disease and LV ejection fraction of 0.35 or less were included. All patients underwent SVR and additionally coronary artery bypass grafting or mitral valve surgery if clinically indicated. Clinical and echocardiographic examination was performed before SVR and at 6 months' follow-up. The primary end point was a composite of all-cause mortality and hospitalizations for heart failure. RESULTS: At 6 months' follow-up a significant improvement in heart failure symptoms was noted. In addition, LV ejection fraction increased from 0.27 ± 0.07 to 0.36 ± 0.10 (p < 0.001). During a median follow-up of 2.7 years, the primary end point was recorded in 22% of the patients. Baseline New York Heart Association functional class IV and a 6-month follow-up LV end-systolic volume index of at least 60 mL/m(2) were independently associated with worse outcome (hazard ratio, 5.4; 95% confidence interval, 1.9 to 15.2; p < 0.001; hazard ratio, 2.7; 95% confidence interval, 1.3 to 5.6; p < 0.001, respectively). CONCLUSIONS: Advanced heart failure status at baseline and large residual postsurgery LV end-systolic volume index were independently associated with increased mortality and heart failure hospitalization rates at 2 years' follow-up after SVR.
