There is a paucity of data on safety of calcium channel blockers (CCB) in patients with severe aortic stenosis (AS) and hypertension. Among 2,460 patients with severe AS and hypertension receiving antihypertensive therapy in the CURRENT AS registry-2, we compared the clinical outcomes between patients taking antihypertensive therapy with CCB (CCB group) and without CCB (no CCB group). In the entire study population, CCB was prescribed in 1,763 patients (71.7%), which was the most commonly prescribed antihypertensive agents. The prescription rates of angiotensin converting enzyme inhibitors or angiotensin receptor blockers, beta-blockers, and thiazides were 61.9%, 25.6%, and 7.3% in the CCB group, and 75.8%, 54.4%, and 6.0% in the no CCB group. In the propensity score matched cohort, the cumulative 3-year incidence of all-cause death or hospitalization for heart failure was not different between the CCB and no CCB groups (38.3% vs. 38.7%, log-rank P=0.65; HR, 0.94; 95%CI, 0.77-1.15; P=0.56). The cumulative 3-year incidence of syncope was low regardless of CCB prescription (1.1% vs. 1.0%, P=0.74). Among patients with severe AS and hypertension, CCB was the most commonly prescribed antihypertensive agents, and antihypertensive therapy with CCB was associated with comparable clinical outcomes to antihypertensive therapy without CCB. Syncope was rarely seen in patients with severe AS and hypertension receiving antihypertensive therapy regardless of CCB prescription.

Elevated lipoprotein(a) [Lp(a)] levels are a causal risk factor for peripheral artery disease. However, data on their effect on delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) are limited. The present study assessed the association between elevated Lp(a) levels and delayed wound healing in patients with CLTI. This study included 280 patients who successfully received endovascular therapy for CLTI between September 2016 and August 2021. High Lp(a) levels were defined as those >30 mg/dL. The primary outcome was wound healing. During a median follow-up of 20.4 months (interquartile range 6.8-38.6 months), 146 patients achieved wound healing. The wound healing rate at 24 months was significantly lower in the high Lp(a) than low Lp(a) group (41.1% vs. 86.3%, respectively; P<0.001). The adjusted risk ratio was 0.19 (95% confidence interval 0.13-0.29, P<0.001). Lp(a) levels of 31-50 and >50 mg/dL, but not 16-30 mg/dL, were significantly associated with delayed wound healing relative to Lp(a) levels of ≤15 mg/dL. Elevated Lp(a) levels were independently associated with delayed wound healing in patients with CLTI treated with endovascular therapy.

This study analyzed the risk factors for type 1a endoleak after hybrid thoracic endovascular repair (TEVAR) for aortic arch diseases based on preoperative patient characteristics and multidetector computed tomography measurements. In all, 213 patients who underwent proximal landing zone 1 and 2 hybrid TEVAR for aortic arch pathologies (zone 1, n=82 [38.5%]; zone 2, n=131 [61.5%]; median age 72 years) between May 2008 and February 2020 were enrolled in this study; the median follow-up period was 6.0 years. The rates of type 1a endoleak at 1, 3, 5, and 10 years were 1.4%, 1.4%, 4.1%, and 4.1%, respectively. Multivariate Cox proportional hazard regression analysis revealed that the angle of the aortic arch was a significant risk factor for type 1a endoleak (hazard ratio 1.08; 95% confidence interval 0.85-0.99; P=0.045). The estimated area under the curve in receiver operating characteristic curve analysis was 0.76, and the cut-off value of the aortic arch angle was 95°. It is essential to prevent type 1a endoleak, the most severe complication of hybrid TEVAR. The risk factor for type 1a endoleak in this study was a sharper angle of the aortic arch (≤95°). For patients at high risk of type 1a endoleak, it is necessary to consider alternative procedures depending on a patient's surgical risk.

Fatal arrhythmic events (FAEs), such as sudden cardiac death (SCD) and fatal ventricular arrhythmias, are a devastating complication in patients with coronary artery disease (CAD). Therefore, in this study we aimed to assess the incidence of FAEs in more recent Japanese patients with CAD and to examine whether risk stratification of FAEs can still be feasible using the left ventricular ejection fraction (LVEF). In the CREDO Kyoto PCI/CABG registry cohorts-2 and -3, there were 25,843 patients with LVEF data who received a first coronary revascularization (LVEF ≤35% group: N=1,671, 35%<LVEF≤40% group: N=1,075, 40%<LVEF≤45% group: N=1,594, and LVEF >45%: N=21,503). FAEs were defined as a composite of SCD or hospitalization for serious ventricular arrhythmias. The cumulative 5-year incidence of FAEs was 2.4% and it increased with decreasing LVEF (LVEF ≤35%: 8.84%, 35%<LVEF≤40%: 6.99%, 40%<LVEF≤45%: 4.49%, and LVEF >45%: 1.67%, log-rank P<0.0001). The adjusted risk of FAEs also increased with decreasing LVEF. LVEF is still a strong independent factor for predicting FAEs in patients with CAD in the PCI era. There was no obvious decrease in the incidence of FAEs between the 2 cohorts. The risk factors for FAEs through the 2 cohorts, other than low LVEF, included age ≥75 years, diabetes, heart failure, hemodialysis, atrial fibrillation, and anemia.

An acute hyperglycemic status is reportedly associated with poor prognosis in patients with acute cardiovascular diseases. Although the stress hyperglycemia ratio (SHR) is used to evaluate the hyperglycemic condition on admission, relationships between SHR and clinical outcomes, particularly heart failure (HF), remain uncertain in acute myocardial infarction (AMI). This retrospective multicenter study included 2,386 patients with AMI undergoing percutaneous coronary intervention. SHR was calculated using blood glucose and HbA1c levels. Co-primary endpoints included HF-related events (death, worsening HF, and hospitalization for HF) and major adverse cardiovascular events (MACE; death, recurrent AMI, and ischemic stroke) during the index hospitalization and after discharge. The mean (±SD) SHR was 1.30±0.51; HF events and MACE occurred in 680 (28.5%) and 233 (9.8%) patients during hospitalization, respectively. SHR was independently associated with in-hospital HF events and MACE. Of 2,017 patients who survived to discharge, 195 (9.7%) and 214 (10.6%) experienced HF events and MACE, respectively, over a median follow-up of 536 days. The risk of HF events was higher in patients with a high (>1.45) SHR than in those with SHR ≤1.45; there was no significant difference in MACE rates after discharge between these 2 groups. In AMI patients, SHR was predictive of in-hospital outcomes, including HF events and MACE, whereas after discharge a higher SHR was associated with higher HF risks, but not MACE.
