Malnutrition leads to the progression of coronary artery calcification in hemodialysis patients

Hiroki Okabe, Yoshitaka Muraoka, Yutaro Naka, Koshi Setoyama et autres

BACKGROUND: Malnutrition is considered a risk factor for cardiovascular disease in patients with chronic kidney disease. However, no in vivo studies have reported on using optical coherence tomography to evaluate the effect of nutritional status on coronary atherosclerosis in hemodialysis patients. We …

PS-C04-11: EFFECT OF ANKLE BRACHIAL INDEX EXAMINATION ON CENTRAL AORTIC BLOOD PRESSURE IN PATIENTS WITH PERIPHERAL ARTERY DISEASE

Shinjo Sonoda, Toshiya Miura, Reo Anai, Kuninobu Kashiyama et autres

Background: Ankle brachial index (ABI) measurements are useful for detecting peripheral artery disease (PAD) as a screening test. In general, ABI examinations are contraindicated in patients with aortic aneurysm and history of aortic aneurysm. However, little is known whether ABI examinations elevate …

Clinical Efficacy of Intracoronary Papaverine After Nicorandil Administration for Safe and Optimal Fractional Flow Reserve Measurement

Konosuke Inoue, Shinjo Sonoda, Yutaro Naka, Hiroki Okabe et autres

Fractional flow reserve (FFR) is considered the standard for assessment of the physiological significance of coronary artery stenosis. Intracoronary papaverine (PAP) is the most potent vasodilator used for the achievement of maximal hyperemia. However, its use can provoke ventricular tachycardia (VT) due …
