Prognostic value of NT-proBNP in patients with chronic coronary syndrome and normal left ventricular systolic function according to glucose status: a prospective cohort study.

ABSTRACT:

Background

The prognostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with coronary artery disease (CAD) with different glucose status has not been established. This study sought to evaluate the significance of NT-proBNP in predicting major adverse cardiovascular events (MACEs) in patients with chronic coronary syndrome (CCS) and normal left-ventricular systolic function (LVSF) according to different glucose status, especially in those with abnormal glucose metabolism.

Methods

A total of 8062 patients with CCS and normal LVSF were consecutively enrolled in this prospective study. Baseline plasma NT-proBNP levels were measured. The follow-up data of all patients were collected. Kaplan-Meier and Cox regression analyses were used to assess the risk of MACEs according to NT-proBNP tertiles stratified by glucose status.

Results

Over an average follow-up of 59.13 ± 18.23 months, 569 patients (7.1 %) suffered from MACEs, including cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Kaplan-Meier analysis showed that high NT-proBNP levels had a significant association with MACEs in subjects with prediabetes mellitus (pre-DM) or DM, but not in patients with normoglycemia. Multivariate Cox regression analysis revealed that NT-proBNP remained an independent predictor of MACEs in patients with pre-DM [hazard ratio (HR): 2.56, 95% confidence interval (CI): 1.34-4.91] or DM (HR: 2.34, 95% CI: 1.32-4.16). Moreover, adding NT-proBNP to the original Cox model including traditional risk factors significantly increased the C-statistic by 0.035 in pre-DM and DM, respectively.

Conclusions

The present study indicated that NT-proBNP could well predict worse outcomes in dysglycemic patients with CCS and normal LVSF, suggesting that NT-proBNP may help with risk stratification in this population.

Project description:ObjectiveTo determine predictors of adverse outcomes in peripartum cardiomyopathy (PPCM).Methods and resultsWe conducted a multi-center cohort study across four centers to identify subjects with PPCM with the following criteria: LVEF <40%, development of heart failure within the last month of pregnancy or within 5 months of delivery and no other identifiable cause of heart failure with reduced ejection fraction. Outcomes included 1) survival free from major adverse events (need for extra-corporeal membrane oxygenation, ventricular assist device, orthotopic heart transplantation or death) and 2) LVEF recovery ≥ 50%. Using a univariate logistic regression analysis, we identified significant clinical predictors of these outcomes, which were then used to create multivariable models. NT-proBNP at the time of diagnosis was examined both as a continuous variable (log transformed) in logistic regression and as a dichotomous variable (values above and below the median) using the log-rank test. In all, 237 women (1993 to 2017) with 736.4 person-years of follow-up, met criteria for PPCM. Participants had a mean age of 32.4 ± 6.7 years, mean BMI 30.6 ± 7.8 kg/m2; 63% were White. After median follow-up of 3.6 years (IQR 1.1-7.8), 113 (67%) had LVEF recovery, and 222 (94%) had survival free from adverse events. Significant predictors included gestational age, gravidity, systolic blood pressure, smoking, heart rate, initial LVEF, and diuretic use. In a subset of 110 patients with measured NTproBNP levels, we found a higher event free survival for women with NTproBNP <2585 pg/ml (median) as compared to women with NTproBNP ≥2585 pg/ml (log-rank test p-value 0.018).ConclusionGestational age, gravidity, current or past tobacco use, systolic blood pressure, heart rate, initial LVEF and diuretic requirement at the time of diagnosis were associated with survival free from adverse events and LVEF recovery. Initial NT-proBNP was significantly associated with event free survival.

Project description:Background. Mineral metabolism (MM) system and N-terminal pro-brain natriuretic peptide (NT-ProBNP) have been shown to add prognostic value in patients with stable coronary artery disease (SCAD). However, the influence of NT-ProBNP on the prognostic role of MM in patients with SCAD has not been shown yet. The objective of this study is to assess the influence of NT-ProBNP on the prognostic role of MM markers in patients with SCAD. Methods: We analyzed the prognostic value of MM markers (parathormone (PTH), klotho, phosphate, calcidiol (25-hydroxyvitamin D3), and fibroblast growth factor-23) in 964 patients with SCAD and NT-ProBNP > 125 pg/mL vs. patient with NT-ProBNP ≤ 125 pg/mL included in five hospitals in Spain. The main outcome was the combination of death, heart failure, and ischemic events (any acute coronary syndrome, ischemic stroke, or transient ischemic attack). Results: A total of 622 patients had NT-proBNP > 125 pg/mL and 342 patients had NT-ProBNP ≤ 125 pg/mL. The median follow-up was 5.1 years. In the group of NT-proBNP > 125 pg/mL, the patients were older, and there were more females and smokers than in the group of patients with normal NT-proBNP. Additionally, the proportion of patients with hypertension, atrial fibrillation, ejection fraction < 40%, cerebrovascular attack, or prior coronary artery bypass graft was higher in the high NT-proBNP group. In the high NT-proBNP patients, the predictors of poor prognosis were PTH (HR = 1.06 (1.01–1.10), p < 0.001) and NT-proBNP (HR = 1.02 (1.01–1.03), p = 0.011), along with age (HR = 1.039 (1.02–1.06), p < 0.001), prior coronary artery bypass graft (HR = 1.624 (1.02–2.59), p = 0.041), treatment with statins (HR = 0.32 (0.19–0.53), p < 0.001), insulin (HR = 2.49 (1.59–4.09), p < 0.001), angiotensin receptor blockers (HR = 1.73 (1.16–2.56), p = 0.007), nitrates (HR = 1.65 (1.10–2.45), p = 0.014), and proton pump inhibitors (HR = 2.75 (1.74–4.36), p < 0.001). In the NT-proBNP ≤ 125 pg/mL subgroup, poor prognosis predictors were plasma levels of non-high-density lipoprotein (non-HDL) cholesterol (HR = 1.01 (1.00–1.02), p = 0.014) and calcidiol (HR = 0.96 (0.92–0.99), p = 0.045), as well as treatment with verapamil (HR = 11.28 (2.54–50.00), p = 0.001), and dihydropyridines (HR = 3.16 (1.63–6.13), p = 0.001). Conclusion: In patients with SCAD and NT-ProBNP > 125 pg/mL, PTH and NT-ProBNP, which are markers related to ventricular damage, are predictors of poor outcome. In the subgroup of patients with NT-ProBNP ≤ 125 pgm/L, calcidiol and non-HDL cholesterol, which are more related to vascular damage, are the independent predictors of poor outcome. Then, in patients with SCAD, baseline NT-ProBNP may influence the type of biomarker that is effective in risk prediction.

Project description:AimsRecent 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 resultsThis 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.ConclusionsSodium 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.
