OBJECTIVE: Tibial artery calcification (TAC) is associated with increased risk of amputation and mortality in peripheral artery disease. We sought to investigate whether the severity of TAC based on semiquantitative analysis of computed tomography angiography (CTA) can predict outcomes of endovascular therapy in patients with critical limb ischemia. METHODS: We reviewed medical records of 124 patients who underwent lower extremity CTA before intervention. Based on CTA, TAC severity was categorized into three groups: minimal calcification (MC; n = 43), intermediate calcification (IC; n = 36), or extensive calcification (EC; n = 45)...

We highlight the presence of a calcified mass in the left main coronary artery without significant atherosclerosis seen in the other coronary arteries or in the peripheral large arteries. In our view, the calcified character of the obstruction and the calcification of the aortic valve are characteristic of a variant type of coronary artery disease (CAD) not associated with the same risk factors as diffuse coronary atherosclerosis, but, in this case, with rheumatic heart disease. This case report also emphasizes the interventional approach for patients with aortic valve stenosis secondary to rheumatic heart disease...

Peripheral arterial disease (PAD) is a global health issue that is becoming more prevalent in an aging world population. Diabetes mellitus and chronic kidney disease are also on the increase, and both are associated with accelerated vascular calcification and an unfavorable prognosis in PAD. These data challenge the traditional athero-centric view of PAD, instead pointing toward a disease process complicated by medial arterial calcification. Like atherosclerosis, aging is a potent risk factor for medial arterial calcification, and accelerated vascular aging may underpin the devastating manifestations of PAD, particularly in patients prone to calcification...

Cardiovascular disease is the leading cause of morbidity and mortality in the world. Atherosclerotic plaques, consisting of lipid-laden macrophages and calcification, develop in the coronary arteries, aortic valve, aorta, and peripheral conduit arteries and are the hallmark of cardiovascular disease. In humans, imaging with computed tomography allows for the quantification of vascular calcification; the presence of vascular calcification is a strong predictor of future cardiovascular events. Development of novel therapies in cardiovascular disease relies critically on improving our understanding of the underlying molecular mechanisms of atherosclerosis...

BACKGROUND: Ankle brachial index can be falsely elevated in cases of medial arterial calcification, and its clinical use should be limited, especially in patients with diabetes. The aim of this study was to evaluate the potential role of pulse volume recording in detecting falsely elevated ankle brachial index. METHODS: Two parameters of the pulse waveform were automatically calculated: upstroke time and percentage mean artery pressure. Pulse volume recordings were retrospectively evaluated in 171 consecutive patients (342 limbs); 73 (43%) had a diagnosis of diabetes...

There is a growing literature indicating that genetic variants modify many of the associations between environmental exposures and clinical outcomes, potentially by increasing susceptibility to these exposures. However, genome-scale investigations of these interactions have been rarely performed particularly in the case of air pollution exposures. We performed race-stratified genome-wide gene-environment interaction association studies on European-American (EA, N = 1623) and African-American (AA, N = 554) cohorts to investigate the joint influence of common single nucleotide polymorphisms (SNPs) and residential exposure to traffic ("traffic exposure")-a recognized vascular disease risk factor-on peripheral arterial disease (PAD)...
