Atherosclerosis

Ankle-brachial index (ABI) screening is recommended for the detection of asymptomatic peripheral arterial disease (PAD) in at-risk populations, including diabetics. A low ABI identifies obstructive lower extremity vascular disease and predicts CVD events and increased mortality. A high ABI represents non-compressible arterial disease (NCAD), and is also associated with increased mortality and vascular events. Our objective is to investigate whether low and high ABI have distinct patterns of association with cardiovascular disease (CVD) risk factors and subclinical atherosclerosis in individuals with type-II diabetes mellitus. ⋯ NCAD bears a distinct relationship to traditional CVD risk factors among diabetics, though like PAD is independently associated with increased CAC. These findings support the recognition of NCAD as a high-risk phenotype and provide additional relevance to ABI screening in diabetics.

Review Meta Analysis
Obstructive sleep apnea and cardiovascular risk: meta-analysis of prospective cohort studies.
Previous studies suggest obstructive sleep apnea (OSA) may increase cardiovascular risk, but the results are inconclusive due to various limitations. We aimed to systematically evaluate the effect of OSA on the incidence of cardiovascular events by a meta-analysis of prospective cohort studies. ⋯ In conclusion, findings from this meta-analysis supported that moderate-severe OSA significantly increased cardiovascular risk, in particular stroke risk.

Apolipoprotein (apo) B is highly predictive of coronary risk, especially in patients with high triglycerides (TG). This post hoc analysis evaluated the effects of lipid-lowering therapy on correlations between apoB and low-density lipoprotein cholesterol (apoB:LDL-C) and non-high-density lipoprotein cholesterol (apoB:non-HDL-C) in patients with TG< and ≥ 200 mg/dL. ⋯ After treatment with EZE, SIMVA, or EZE/SIMVA, a given apoB value corresponds to lower LDL-C and non-HDL-C levels than those obtained from untreated patients.
