Clinical Outcomes in Type 2 Diabetes Patients After Acute Myocardial Infarction: A Comparison of Sodium-Glucose Cotransporter 2 Inhibitors vs. Non-Users.

To compare clinical outcomes in patients with type 2 diabetes (T2D) after acute myocardial infarction (AMI) using sodium-glucose cotransporter-2 inhibitors (SGLT2i) vs. non-use of SGLT2i. A national cohort study based on the Taiwan National Health Insurance Research Database enrolled 944 patients with T2D who had experienced AMI and were treated with SGLT2i and 8,941 patients who did not receive SGLT2i, respectively, from May 1, 2016, to December 31, 2019. We used propensity score matching to balance covariates across study groups. The follow-up period was from the index date to the independent occurrence of the study outcomes, discontinuation of the index drug, or the end of the study period (December 31, 2020), whichever occurred first. The SGLT2i group exhibited a significantly lower incidence of cardiovascular death (0.865% per year vs. 2.048% per year; hazard ratio (HR): 0.42; 95% confidence interval (CI): 0.24-0.76; P = 0.0042), heart failure hospitalization (1.987% per year vs. 3.395% per year; HR: 0.59; 95% CI: 0.39-0.89; P = 0.0126), and all-cause mortality (3.406% per year vs. 4.981% per year, HR: 0.69; 95% CI: 0.50-0.95; P = 0.0225) compared with the non-SGLT2i group. There were no significant differences between the two groups in the incidence of AMI, ischemic stroke, coronary revascularization, major adverse cardiovascular events, composite renal outcomes, or lower limb amputation. These findings suggest that the use of SGLT2i may have favorable effects on clinical outcomes in patients with T2D after AMI.

Clinical Benefit of Fixed-Dose Combination of Amlodipine and Potent Atorvastatin in Patients With Concomitant Hypertension and Hypercholesterolemia.

BACKGROUND: Hypertension and hypercholesterolemia are important risk factors for cardiovascular disease, and treatment with fixed-dose combination (FDC) regimens is recommended by current guidelines. However, the clinical outcomes of different FDC dosages remain unknown. This study aimed to examine the clinical outcomes of FDC regimens and the free combination of amlodipine and atorvastatin at different dosages. METHODS AND RESULTS: Patients with concurrent hypertension and hypercholesterolemia treated daily with an FDC of 5 mg amlodipine and 10 mg atorvastatin (5/10 fixed group), and FDC of 5 mg amlodipine and 20 mg atorvastatin (5/20 fixed group), or free combination of 5 mg amlodipine and 20 mg atorvastatin (5/20 free group) were identified from the National Health Insurance Research Database of Taiwan. The primary outcome was the composite cardiovascular outcomes, including cardiovascular death, acute myocardial infarction, stroke, and coronary intervention. A total of 9095 patients were eligible for inclusion. The incidence of primary outcome per 1000 person-years was 16.6 in the 5/10 fixed group, 12.6 in the 5/20 fixed group, and 16.5 in the 5/20 free group (5/20 fixed versus 5/20 free: hazard ratio [HR], 0.76 [95% CI, 0.64-0.91]; 5/20 fixed versus 5/10 fixed: HR, 0.76 [95% CI, 0.63-0.90]). CONCLUSIONS: Among patients with concomitant hypertension and hypercholesterolemia, treatment with an FDC of amlodipine and high-dose atorvastatin led to a lower risk of a composite of cardiovascular outcomes than treatment with the free combination or a similar FDC with a lower dose of atorvastatin.

High Triglyceride Variability Increases the Risk of First Attack of Acute Pancreatitis.

INTRODUCTION: Hypertriglyceridemia is the third most common etiology of acute pancreatitis. Whether triglyceride variability, independent of absolute triglyceride levels, is a predictor of acute pancreatitis is unknown. METHODS: We identified 98,819 patients who were diagnosed with hyperlipidemia between January 1, 2007, and December 31, 2013, and had at least 1 triglyceride measurement annually for 4 consecutive years from the Chang Gung Research Database in Taiwan. Triglyceride variability, defined as variability independent of the mean, was calculated in the 4-year run-in period. The patients were stratified according to the quartiles of triglyceride variability and were followed until December 31, 2019, for first attack of acute pancreatitis. RESULTS: During a mean follow-up of 5.9 years, 825 (0.83%) patients were newly diagnosed with acute pancreatitis (14.1 events per 10,000 person-years; 95% confidence interval 13.2-15.1). Triglyceride variability was significantly associated with an increased risk of acute pancreatitis, independent of baseline triglyceride and mean triglyceride levels (hazard ratio, 1.28 [95% confidence interval 1.05-1.57] for the highest vs the lowest quartiles of triglyceride variability; P for trend = 0.006 over the quartiles of triglyceride variability). Subgroup analysis showed that this association was more pronounced among the patients with a higher neutrophil-to-lymphocyte ratio ( P for trend = 0.022). DISCUSSION: In this multi-institutional cohort study, high triglyceride variability was associated with an increased risk of first attack of acute pancreatitis, independent of baseline and mean triglyceride levels. The association between triglyceride variability and acute pancreatitis may be partly mediated by subclinical inflammation.

Efficacy and safety outcomes of one generic nifedipine versus ADALAT long-acting nifedipine for hypertension management.

Data regarding the long-term outcomes of generic antihypertensive drugs are limited. This nationwide retrospective database analysis aimed to evaluate the efficacy and safety of a generic versus brand-name nifedipine for hypertension treatment. Patients who were prescribed generic or brand-name nifedipine between January 1, 2008, and December 31, 2013, were identified from the National Health Insurance Research Database of Taiwan. The efficacy outcomes included all-cause mortality and the composite cardiovascular (CV) outcome, including CV death, non-fatal myocardial infarction, non-fatal stroke, coronary revascularization, and hospitalization for heart failure. Safety outcomes included headache, peripheral edema, constipation, acute kidney injury, hypotension, syncope, new diagnosis of cancer, and cancer death. Among the 98 335 patients who were eligible for analysis, 21 087 (21.4%) were prescribed generic nifedipine. Both the generic and the brand-name groups included 21 087 patients after propensity score matching. At a mean follow-up of 4.1 years, the generic nifedipine was comparable to the brand-name drug with regard to all-cause mortality (7.2% vs. 7.1%; hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.95-1.09) and the composite CV outcomes (11.6% vs. 11.9%; HR 0.97; 95% CI 0.92-1.03). The generic nifedipine was associated with higher rates of headache, peripheral edema, and constipation but a modest reduction in the risk of newly diagnosed cancer (7.1% vs. 7.8%; subdistribution HR 0.90, 95% CI 0.84-0.97). The risks of acute kidney injury, hypotension, syncope, and cancer death were not significantly different between the two groups. In conclusion, the generic nifedipine was comparable to the brand-name drug with regard to the risks of all-cause mortality and the composite CV outcome. The finding of cancer risk could be chance and should be interpreted with caution.

Sodium glucose cotransporter-2 inhibitor was associated with an improvement in left ventricular systolic function in patients with type 2 diabetes mellitus with impaired left ventricular systolic function.

AIMS: Recent studies indicated that sodium glucose cotransporter-2 inhibitors (SGLT2i) reduced heart failure hospitalization in patients with type 2 diabetes mellitus (T2DM). However, whether SGTL2i can improve left ventricular (LV) systolic and diastolic function remained unclear. This study aimed to compare the change in echocardiographic parameters in T2DM patients receiving SGLT2i with a different baseline LV ejection fraction (LVEF). The change in echocardiographic parameters was also compared between T2DM patients treated with SGLT2i and those treated with dipeptidyl peptidase-4 inhibitor (DPP4i). METHODS AND RESULTS: This multicentre cohort study consecutively enrolled 665, 119, and 132 T2DM patients treated with SGLT2i with a preserved (≥50%), moderately reduced (40-50%), and reduced baseline LVEF (<40%), respectively, with paired baseline and post-treatment echocardiographic data available between 1 June 2016 and 31 May 2018. There were 212 patients treated with DPP4i with paired baseline and post-treatment echocardiographic data available at the same time. For those patients treated with DPP4i, 45 patients had impaired baseline LVEF of <50%. Echocardiographic parameters, including LVEF, LV end-diastolic volume, LV end-systolic volume (LVESV), and LV diastolic function, were analysed at baseline and after treatment. After a median SGLT2i treatment period of 230 days, patients with reduced LVEF were associated with an improvement in LVEF from 29.4 ± 7.4% to 42.2 ± 15.2% (P < 0.0001) and decrease in LVESV from 133.2 ± 49.2 to 117.4 ± 60.1 mL (P = 0.0002). Patients with moderately reduced LVEF were associated with an improvement in LVEF from 44.8 ± 2.9% to 49.7 ± 12.4% (P < 0.0001) and decrease in LVESV from 90.7 ± 31.1 to 80.0 ± 36.2 mL (P = 0.0017). Patients with preserved LVEF did not show an improvement in LVEF and LVESV after SGLT2i treatment. There were no significant changes of LV end-diastolic volume, LV diastolic function, and LV wall thickness in three study groups after SGLT2i treatment. In contrast, patients with impaired baseline LVEF (<50%) did not show any change in LVEF and LVESV after DPP4i treatment. CONCLUSIONS: Sodium glucose cotransporter-2 inhibitor was associated with an improvement in LV systolic function in patients with T2DM with reduced and moderately reduced LVEF. In contrast, DPP4i treatment was not associated with any improvement in LVEF among patients with impaired LVEF.
