Changes in triglyceride, HDL-C, and non-HDL-C levels in patients with acute coronary syndrome

Is the variation in monocyte to high-density lipoprotein cholesterol ratio a predictor of major cardiovascular events after acute coronary syndrome?

In clinical practice, we need to develop new tools to identify the residual cardiovascular risk after acute coronary syndrome (ACS). This study aimed to evaluate whether the monocyte to high-density lipoprotein cholesterol ratio (MHR) variation (ΔMHR) obtained during hospital admission (MHR1) and repeated in the first outpatient evaluation (MHR2) is a predictor of major adverse cardiovascular events (MACE) after ACS. One hundred ninety-one patients admitted for ACS were prospectively included. The ΔMHR was calculated by subtracting MHR1 from MHR2. Patients were followed for 166±38 days in which the occurrence of MACE was observed. The best cutoff for ΔMHR was zero (0), and individuals were divided into two groups: ΔMHR<0 (n=113) and ΔMHR≥0 (n=78). The presence of MACE was higher in the ΔMHR≥0 (22%) than in the ΔMHR<0 (7%), with a hazard ratio (HR) of 3.96 (95% confidence interval [CI]: 1.74-8.99; P=0.0004). After adjusting for confounders, ΔMHR≥0 remained an independent MACE predictor with an adjusted HR of 3.13 (95%CI: 1.35-7.26, P=0.008). In conclusion, our study showed that ΔMHR was an independent MACE predictor after ACS. Thus, ΔMHR is a potential marker of residual cardiovascular risk after ACS.

Blood group B and decreased risk of coronary artery disease in hypertensive elderly

Although ABO blood groups have been associated with cardio-vascular disease, little is known about whether ABO blood groups contribute to the risk of the presence and severity of coronary artery disease (CAD) in elderly individuals with hypertension. This study was aimed to explore this as-sociation. A total of 793 hypertensive patients aged ≥60 years out of 2095 patients who underwent primary coronary angiography were retrospectively included. They were divided into CAD and non-CAD groups. Demographic and clinical characteristics, ABO blood groups and other biochemical parameters were compared. Further evaluation was performed to determine the impact of ABO blood groups on CAD severity using the Gensini score and the number of significantly diseased vessels. A logistic regression model was constructed to identify the association of ABO blood groups with CAD. There was a substantial difference in the distribution of ABO blood groups in elderly and hypertensive adults with and without CAD (p=0.022). Hypertensive patients with CAD had a significantly lower proportion of the blood group B than those without CAD (p=0.008). Compared to those with non-Blood group B, hypertensive elderly with a blood group B tended to have significantly lower concentrations of TC, LDL -C and Apo B, and a lower number of significantly stenosed vessels. The blood group B was found to be an independent protective factor for CAD in elderly with hypertension. The blood group B is significantly associated with a decreased risk of CAD and is inversely correlated with the severity of coronary stenosis in the elderly with hypertension.

Ten-year Time-trend Analysis of Dyslipidemia Among Adults in Wuhan

OBJECTIVE

Dyslipidemia is associated with an increased risk of cardiovascular disease, the major cause of death in an aging population. This study aimed to estimate the prevalence of dyslipidemia for the past decade among adults in Wuhan, China.

METHODS

We performed a serial cross-sectional study that recruited 705 219 adults from the Health Management Center of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from 2010 to 2019. The diagnosis of dyslipidemia was based on the 2016 Chinese Guidelines for the Management of Dyslipidemia in Adults. Fixed effects and random effects models were applied to adjust the confounding variables (gender and age).

RESULTS

The overall prevalence of dyslipidemia was 33.1% (46.2% in men and 14.7% in women) in 2019. The prevalence of dyslipidemia was significantly increased over 10 years [from 28.6% (95% CI: 28.2%-29.1%) in 2010 to 32.8 % (95% CI:32.6%-33.1%) in 2019;. P-0.001], especially for hypo-high-density lipoprotein cholesterolemia [from 18.4% (95% CI: 18.0%-18.8%) in 2010 to 24.5% (95% CI: 24.3%-24.7%) in 2019; P-0.001]. In 2019, the prevalence of dyslipidemia was higher in participants with comorbidities, including overweight/obesity, hypertension, diabetes, hyperuricemia, or chronic kidney disease, and dyslipidemia was the most significant among participants aged 30-39 years.

CONCLUSION

This study demonstrated that dyslipidemia is on the rise in men, and more emphasis should be provided for the screening of dyslipidemia in young males for the primary prevention of cardiovascular and renal diseases.
