10 “Triada Lipidica” : Mayor Riesgo Coronario Vs c-LDL aisladamente alto

Patients enrolled into this study had a history of CHD and had total cholesterol levels of 5.5 to 8.0 mmol/L (210 to 310 mg/dL).1 The analysis shown here provides rates of major coronary events, on the left, and coronary mortality, on the right, for 2 distinct subgroups of patients: those with isolated LDL-C elevations who were in the highest quartile for HDL-C and lowest quartile for triglycerides, represented by the orange bars; and, those with the “lipid triad” who had elevated LDL-C and were in the lowest quartile for HDL-C and highest quartile for triglycerides, and are represented by the yellow bars. At baseline, patients with the lipid triad had a mean LDL-C of 4.91 mmol/L (190 mg/dL), mean HDL-C of 0.85 mmol/L (33 mg/dL), and a mean triglyceride level of 2.23 mmol/L (198 mg/dL). Patients with isolated LDL-C elevation had a mean LDL-C level of 4.67 mmol/L (181 mg/dL) at baseline, with mean values of 1.62 mmol/L (63 mg/dL) and 0.89 mmol/L (79 mg/dL) for HDL-C and triglycerides, respectively.1 The 5-year rate of major coronary events was higher among patients with the lipid triad (35.9%) versus patients with only elevation of LDL-C (20.9%).1 These events included coronary death, definite or probable hospital-verified nonfatal acute myocardial infarction, resuscitated cardiac arrest, and definite silent myocardial infarction, as verified by electrocardiogram.1 The 5-year rate of CHD death was also markedly higher among patients with the lipid triad at baseline (12.2%) versus patients with isolated elevation of LDL-C (8.5%).1 These findings support the conclusion that the lipid triad of the lowest levels of HDL-C and the highest levels of triglycerides in the presence of elevated LDL-C places patients at very high risk for CHD events compared with isolated LDL-C elevations.1 10 8.5 5 (n=284) (n=237) (n=284) (n=237) Eventos coronarios mayores Mortalidad Coronaria Adapted from Ballantyne CM et al.

A recent meta-analysis by Sarwar et al1 included 29 prospective studies and was the largest and most comprehensive epidemiological assessment of the association between triglyceride values and CHD risk in Western populations ( participants; 10,158 CHD cases). A combined analysis of the 29 studies yielded an adjusted odds ratio of 1.72 (95% CI, ) in a comparison of extreme thirds of usual triglyceride values (ie, individuals with usual log-triglyceride values in the top third of the population compared with those in the bottom third). This odds ratio was adjusted in all but one study for at least age, sex, smoking status, lipid concentrations, and most studies also adjusted for blood pressure. The above figure shows the CHD risk ratio adjusted for several established risk factors and grouped according to several study characteristics (ie, duration of follow-up, sex, fasting status, and adjusted for HDL-cholesterol). The data indicate that the impact of triglycerides on CHD risk is similar in women and men and also regardless of duration of follow up. The data suggest no important differences in the strength of associations between triglycerides and CHD in studies of fasting participants compared with studies of nonfasting participants. Finally, adjustment for HDL-cholesterol attenuated the magnitude of the association between triglyceride level and CHD risk. The conclusion of the study is that there is a strong and highly significant association between triglyceride value and CHD risk. Reference 1. Sarwar N, et al.

A meta-analysis of 53 trials using fibrates or placebo was conducted.1 Statistically significant reductions in major coronary events (P<0.001) were shown only in the VA-HIT Trial and the Helsinki Heart Study.1 Other long-term trials (ie, Bezafibrate Coronary Atherosclerosis Intervention Trial [BECAIT], Bezafibrate Infarction Prevention Study, and the Bezafibrate Treatment in Lower Extremity Arterial Disease Event Reduction trial) showed tendencies toward significance in reduction in major coronary events (P=0.07).1 Pooled studies with the fibrates indicated a significant reduction in coronary events but no statistically significant reductions in mortality due to coronary cause or all cause.1 Ref 1, p189, C1, ¶cont, L 5-7 NS=No Significativo; CV=cardiovascular Birjmohun RS et al.
