硫氮酮和异搏定治疗高血压时的血脂变化

53例原发性高血压患者,随机分为两组,分别用硫氮酮(diltiazem)和异搏定(verapamil)治疗,疗程4周。用双盲法观察降压效果和血脂改变。结果两组均示有明显降压效果,硫氮(艹卓)酮的降压效果又明显大于异搏定。治疗后的血脂改变,两组均显示有:HDL-C,HDL-C/TC比值,HDL_C/LDL-C比值和ApoAl的升高,且两组间比较无显著差异。这些改变均有利于防止动脉粥样硬化,故认为,两者对血脂代谢的影响虽相似,但硫氮(艹卓)酮对心脏抑制作用较异搏定为轻,降压疗效较异搏定为佳,故在治疗高血压时,硫氮(艹卓)酮更值得推广应用。     

Use of the plasma triglyceride/high-density lipoprotein cholesterol ratio to identify cardiovascular disease in hypertensive subjects

This analysis evaluated the hypothesis that the plasma triglyceride (TG)/high–density lipoprotein cholesterol (HDL-C) concentration ratio can help identify patients with essential hypertension who are insulin–resistant, with the cardiovascular disease (CVD) risk profile associated with that defect. Data from a community–based study developed between 2003 and 2012 were used to compare CVD risk factors and outcome. Plasma TG/HDL-C cut–points of 2.5 (women) and 3.5 (men) subdivided normotensive (n = 574) and hypertensive (n = 373) subjects into “high” and “low” risk groups. Metabolic syndrome criteria (MetS) were also used to identify “high” and “low” risk groups. The baseline cardio–metabolic profile was significantly more adverse in 2003 in “high” risk subgroups, irrespective of BP classification or definition of risk (TG/HDL-C ratio vs. MetS criteria). Crude incidence of combined CVD events increased across risk groups, ranging from 1.9 in normotensive–low TG/HDL-C subjects to 19.9 in hypertensive–high TG/HDL-C ratio individuals (P for trends <.001). Adjusted hazard ratios for CVD events also increased with both hypertension and TG/HDL-C. Comparable findings were seen when CVD outcome was predicted by MetS criteria. The TG/HDL-C concentration ratio and the MetS criteria identify to a comparable degree hypertensive subjects who are at greatest cardio–metabolic risk and develop significantly more CVD.

Long-Term Weight Loss and Metabolic Health in Adults Concerned With Maintaining or Losing Weight: Findings From NHANES

More than two-thirds of American adults are overweight or obese, with many attempting to lose weight to avoid adverse health outcomes and improve well-being. Achieving long-term weight loss (LTWL) success, defined as reaching at least a 5% to 10% weight loss goal, is challenging, yet important for overall metabolic health. It is currently unclear whether achieving higher thresholds of LTWL is associated with improved health. Therefore, the purpose of this study was to examine the association between LTWL thresholds (5%-9.9%, 10%-14.9%, 15%-19.9%, ≥20%) and metabolic health (metabolic syndrome and metabolic risk z score) among 7670 US adult respondents to the National Health and Nutrition Examination Survey (2007-2014) who were overweight or obese (past or present), were not underweight in the past year, not pregnant, and attempting to lose or maintain weight. A subsample of 3362 participants was used in the analysis of the metabolic risk z score. Multivariable regression models were constructed adjusting for covariates. Results indicate that the lowest and the 2 highest LTWL thresholds were related to lower odds for metabolic syndrome; for example, greater than or equal to 20% LTWL (odds ratio=0.52; 95% CI, 0.23-0.44; P<.001). All LTWL thresholds were significantly associated with the metabolic risk z score, with the largest effect among the 2 highest LTWL thresholds, that is, 15% to 19.9% LTWL (β=?0.45; 95% CI, ?0.54 to ?0.36; P<.001) and greater than or equal to 20% LTWL (β=?0.35; 95% CI, ?0.53 to ?0.17; P<.001). In conclusion, although achieving the currently recommended LTWL target was related to improved metabolic health, the 15% LTWL threshold was associated with more favorable outcomes.
