北西孝紀教授の研究室は、心疾患の発症メカニズムや予後予測に関する画像診断・生体情報の包括的解析を柱としています。特に心房細動の予測因子としての心膜外脂肪(EAT)量や、冠 artery 病変と関連する腎機能障害の関連、および動脈硬化のバイオマーカーとしての血流制御機能(CFR)や血圧変動の脳への影響を、多スライスCT や2Dエコー、ABPMを用いて解明しています。高齢者における心拍数や血圧の夜間パターンが脳虚血像に与える影響についても、神経循環代謝の分野と融合した研究を推進しています。

This is the first study demonstrating that peri-atrial EAT volume estimated by MDCT excellently predicted the development of new-onset AF in patients with CAD, independent of LA enlargement.
This TTDE study demonstrated that CFR was a significant and independent determinant of long-term cardiovascular events, ACS events and HF in patients with coronary artery disease. A CFR greater than 2.0 was not suitable to predict a favorable long-term outcome, even in the absence of obstructive coronary narrowing.
Significant residual TR was observed in ≈25% patients supported with LVAD over 1 year and was associated with unfavorable outcome.
Background:Chronic kidney disease (CKD) is strongly associated with coronary artery disease (CAD), although the underlying pathophysiological mechanism remains unclear. Epicardial adipose tissue (EAT) has recently been recognized as an important source of various pro-inflammatory cytokines causing coronary atherosclerosis. This study investigated the relationship between CKD and EAT volume in association with high-risk plaque.Methods and Results:The study included 275 patients with an estimated
Elevated night-time SBP is strongly associated with subclinical cerebrovascular disease. Night-time SBP by ABPM allows to identify individuals at higher risk of hypertensive brain injury.
In a predominantly elderly cohort, elevated nighttime HR was associated with WMHV, suggesting an independent role of HR in subclinical cerebrovascular disease.
Background Chronic kidney disease (CKD) is an independent risk factor for atrial fibrillation, although the pathophysiological mechanisms remain unclear. This study investigated the relationship between CKD and left atrial (LA) volume and function in a sample of the general population without overt cardiac disease. Design and methods We examined 358 participants from the Cardiovascular Abnormalities and Brain Lesions study. The LA minimum volume index (LAVI<sub>min</sub>), LA maximum volume inde
