The Impact

Background: The aim of lipid-lowering treatment is to reduce the risk for cardiovascular events. Patients not at target lipid levels while on hydroxymethylglutaryl coenzyme A reductase inhibitors (statin) monotherapy are at increased cardiovascular risk. Objective: To describe the impact of coadministration of ezetimibe with a statin on the estimated 10 year risk for coronary artery disease (E-RCAD) in patients with hypercholesterolemia and above-target low-density lipoprotein cholesterol (LDL-C) levels after statin monotherapy. Methods: Post hoc analysis was conducted of a prospective, open-label, single-cohort, multicenter Canadian study of 953 patients who were treated for 6 weeks with ezetimibe 10 mg/day coadministered with their current statin at an unaltered dose. For each patient, E-RCAD at baseline and at 6 weeks was calculated using the Framingham model. The primary outcome measure of the analysis was the change in E-RCAD. Results: A total of 825 patients with data at baseline and 6 weeks were included in the analysis. There were 423 (51.3%) patients with hypertension, 107 (13.0%) with diabetes mellitus but not metabolic syndrome, 160 (19.4%) with metabolic syndrome but not diabetes mellitus, and 235 (28.5%) with both diabetes mellitus and metabolic syndrome. After 6 weeks of ezetimibe coadministration with statin therapy, mean E-RCAD was reduced by 4.1% from 15.6% to 11.5%, which is equivalent to a 25.3% risk reduction (p < 0.001). Of the 225 (27.3%) patients with high E-RCAD (≥20.1%) at baseline, 144 (64.0%) converted to a lower E-RCAD category (p < 0.001). Patients with both diabetes mellitus and metabolic syndrome experienced the highest mean percent reduction in E-RCAD of –29.4% (p < 0.001). Conclusions: For patients with above-target LDL-C levels while on statin monotherapy, coadministration of ezetimibe with the statin is effective in significantly reducing the E-RCAD.

The Impact

Abstract Background Familial hypercholesterolemia (FH) is an autosomal dominant trait associated with high risk of premature coronary artery disease (CAD). The worldwide prevalence of FH is estimated at 1:250 to 1:500. In certain populations, including French Canadians (FC), the prevalence is significantly higher however. From 1995 to 1998, FH contributed to 9.6% of angiographically proven CAD in a FC founder population, the burden being the highest in men aged <50 years (20.6%). In the past 2 decades, powerful statins, ezetimibe and other low-density lipoprotein-Cholesterol (LDL-C) modulators, such as PCSK9 inhibitors, have been progressively introduced and several FH diagnosis scoring systems or guidelines have been developed and disseminated in order to facilitate FH recognition and management. The impact of these measures on the FH burden is however not documented. Purpose To compare the burden of FH twenty years apart in FC patients hospitalized for CAD. Methods Lipid profiles, cardiovascular risk factors and FH status of 1,132 FC patients who were hospitalized for a CAD event and who consecutively attended the cardiovascular disease clinic in 2017 and 2018 were compared to those of 2,506 who consecutively presented angiographically proven CAD two decades ago. FH status was based on Simon Broome and FH Canada definitions. In 1998, all consenting CAD patients were also molecularly screened for the most prevalent FH causing mutations in FC. Comparisons between groups were performed using Chi-square and independent samples Student's t-test. Results Most patients in both cohorts were males (74.5% vs 73.9% in 1998 vs. 2018, respectively). At admission, mean LDL-C (± SD) was 3.99±1.67 in 1998 vs. 2.22±1.06 in 2018 (p<0.001). The proportion of patients who were treated with a statin or another lipid lowering agent was 32.9% in 1998 compared to 67.6% in 2018 (p<0.001) and the drug regimen was also significantly different. In 1998, 24.6% of patients had LDL-C >5.0 mmol/L at admission compared to 4.2% in 2018. Definite FH was diagnosed in 9.6% of patients in the 1998 cohort compared to 4.7% in the 2018 cohort (p<0.001). FH patients hospitalized for CAD were significantly older in 2018 than in 1998 (56.3±11.3 vs. 49.2±10.9 in men, p=0.001; 61.1±11.8 vs. 53.2±12.3 in women, p=0.02). In the same period, the relative burden of diabetes and other lipid disorders, including high-density lipoprotein dysmetabolism significantly increased (p<0.001). Conclusions Over a period of 20 years, in a founder population with a high prevalence of FH, the contribution of FH to hospitalizations for CAD decreased by 2-fold and affected patients now tend to be hospitalized at an older age than 2 decades ago. This suggests that early diagnosis and more effective management of FH in the last 2 decades have contributed to significantly decrease its burden. Acknowledgement/Funding ECOGENE-21, Amgen, Sanofi

The Impact

The most relevant comorbidities in patients with peripheral artery disease (PAD) are coronary artery disease (CAD) and diabetes mellitus (DM). However, data of long-term follow-up of patients with chronic total occlusion (CTO) are scarce. The aim of the study was to assess the impact of CAD and DM on long-term follow-up patients after superficial femoral artery (SFA) CTO retrograde recanalization. In this study, eighty-six patients with PAD with diagnosed CTO in the femoropopliteal region and at least one unsuccessful attempt of antegrade recanalization were enrolled in 2 clinical centers. Mean time of follow-up in all patients was 47.5 months (±40 months). Patients were divided into two groups depending on the presence of CAD (CAD group: n=45 vs. non-CAD group: n=41) and DM (DM group: n=50 vs. non-DM group: n=36). In long-term follow-up, major adverse peripheral events (MAPE) occurred in 66.6% of patients with CAD vs. 36.5% of patients without CAD and in 50% of patients with DM vs. 55% of non-DM subjects. There were no statistical differences in peripheral endpoints in both groups. However, there was a statistically significant difference in all-cause mortality: in the DM group, there were 6 deaths (12%) (P value = 0.038). To conclude, patients after retrograde recanalization, with coexisting CTO and DM, are at higher risk of death in long-term follow-up.

A young, 18-year-old lady presented with history of chest pain on exertion typical of angina. General examination revealed multiple tendon xanthomas. Systemic examination was unremarkable. Electrocardiogram showed segment (ST) depression in inferior and lateral leads. Echocardiogram revealed normal left ventricular systolic function and no left ventricular regional wall motion abnormalities. Diastolic flow turbulence was noted in the left main coronary artery and proximal left anterior descending artery on color Doppler interrogation across the coronary arteries. Lipid profile showed unusually high total cholesterol and low-density lipoprotein cholesterol. Subsequent evaluation with coronary angiogram revealed triple vessel coronary artery disease. The patient underwent coronary artery bypass surgery and is on antiplatelet and lipid-lowering drug therapy.

Abstract The presence of the metabolic syndrome (World Health Organization definition) and its association with lipoprotein abnormalities suggestive of greater susceptibility to oxidative stress have been analyzed in patients with angiographically defined coronary artery disease. The odds ratio for the presence of the metabolic syndrome was significantly higher in coronary artery disease-positive patients (P &lt; 0.001). The metabolic syndrome was also associated with more severe coronary disease (P &lt; 0.01). Patients with the metabolic syndrome had significantly decreased low-density lipoprotein-cholesterol/apolipoprotein B and high-density lipoprotein-cholesterol/apolipoprotein AI ratios, indicative of the presence of small, dense lipoprotein particles. The syndrome was also associated with reduced concentrations and activities of the antioxidant enzyme, paraoxonase-1. The metabolic syndrome is characterized by smaller, denser lipoprotein particles that increase their susceptibility to oxidative modifications and diminished serum paraoxonase-1, which is a major determinant of the antioxidant capacity of high-density lipoproteins. These may be contributory factors to the increased presence and severity of coronary disease in such patients.
