Hypertension increases the risk of cerebrovascular disease and death. In addition to aerobic exercise, which is currently recommended for its antihypertensive effects, recent studies have suggested that dynamic and isometric resistance exercises also have antihypertensive effects. However, the magnitude of the antihypertensive effect of such resistance exercises is not well known.

Although hypertension is a major cause of cardiovascular disease, the control of blood pressure (BP) is insufficient worldwide. Exercise is an effective treatment for reducing BP, but the differences in the blood pressure lowering effects of exercise according to the underlying pathophysiological condition, the type of exercise, and the geographic region are not fully understood. An umbrella review with a meta-analysis of 435 randomized controlled trials that investigated the BP-lowering effects of exercise was performed using Ovid MEDLINE and the Cochrane Library, covering the period from inception to August 1, 2023.

Liver fibrosis might be linked to the prevalence of chronic kidney disease (CKD). However, there is little information about the association between liver fibrosis and decreased kidney function in middle-aged and older subjects. We aimed to evaluate the influence of liver fibrosis on the incidence or prevalence of CKD stage 3-5 in a retrospective cross-sectional study (Study 1, = 806) and a 6-year longitudinal study (Study 2, = 380) of middle-aged and older subjects.

There is a lack of data on how to treat hypertensive patients with diabetes when treatment with medium doses of calcium channel blocker and angiotensin II type 1 receptor blocker (ARB) is insufficient to achieve the target blood pressure (BP). A total of 121 participants with type 2 diabetes and uncontrolled essential hypertension, who were receiving medium doses of amlodipine (5 mg/day) and ARB, were enrolled. Participants were randomized to receive either a high dose of amlodipine (10 mg/day) plus a medium dose of ARB (high-AML) or a medium dose of amlodipine (5 mg/day) plus a high dose of ARB (high-ARB).

The associations between microalbuminuria and various parameters of flow-mediated vasodilatation (FMD) are not completely understood. We retrospectively analyzed 265 consecutive patients who underwent coronary angiography and in whom we could measure FMD and the urine albumin-creatinine ratio (UACR). Using 15 continuous measurement approaches, we measured FMD as the magnitude of the percentage change in the brachial artery diameter from baseline to peak (bFMD), the maximum FMD rate calculated as the maximal slope of dilation (FMD-MDR), and the integrated FMD response calculated as the area under the dilation curve during the 60- and 120-s dilation periods (FMD-AUC60 and FMD-AUC120).

We examined whether tolvaptan combined with an angiotensin II receptor blocker (ARB) or angiotensin converting enzyme inhibitor (ACE-I) is more effective than tolvaptan alone in the treatment of patients with heart failure (HF). Sixty-five hospitalized patients with acute decompensated HF were included in this study. They were divided into 2 groups; an ARB/ACE-I group (n = 44, who received ARB or ACE-I before the use of tolvaptan) and a non-ARB/ACE-I group (n = 21).

We investigated the associations between the parameters of flow-mediated vasodilatation (FMD) obtained by continuous measurement approaches and the presence of coronary artery disease (CAD) and the severity of coronary atherosclerosis. The subjects consisted of 282 consecutive patients who underwent coronary angiography (CAG) and in whom we could measure FMD. Using continuous measurement approaches, we measured FMD as the magnitude of the percentage change from brachial artery diameter from baseline to peak (bFMD), the maximum FMD rate calculated as the maximal slope of dilation (FMD-MDR), and the integrated FMD response calculated as the area under the dilation curve during the 60- and 120 s dilation periods (FMD-AUC60 and FMD-AUC120).

  • A hospital implemented a ban on smoking, transitioning from areas for smokers and nonsmokers to a completely smoke-free environment between 2002 and 2007, to reduce the occurrence of acute myocardial infarction (AMI) among admitted patients.
  • Between 2002 and 2014, a study recorded 25 patients who experienced in-hospital AMI, finding a significant decrease in AMI occurrences as the smoke-free zones increased.
  • The results indicated that not only direct smoking but also passive smoking contributed to AMI risk, highlighting the importance of a non-smoking policy in improving patient outcomes.

Congenital coronary artery fistula (CAF) is an infrequent vascular anomaly that establishes a direct link between an epicardial coronary artery and a cardiac chamber, major vessels, or other vascular structures. In this case there was an aneurysmal-CAF between a left main trunk and the right atrium, which was initially diagnosed as a Kawasaki disease by transthoracic echocardiography and subsequently confirmed by coronary angiography and multi-slice CT angiography. A multi-slice CT angiography might well become the modality of choice for the characterization of these rare congenital anomalies.
