Development and application of a home-based exercise program for patients with cardiovascular disease: a feasibility study.

Background: Cardiac rehabilitation (CR) is recommended for patients with cardiovascular disease. However, the participation and completion rates for hospital-based CR are low, and home-based CR has been suggested as an alternative. This study aimed to develop a home-based CR program and assess the feasibility of the program over a 6-week period in patients with left ventricular dysfunction or a history of myocardial infarction.

High intake of sweet foods and low life satisfaction can act as risk factors for acute coronary syndrome through synergistic interaction.

Purpose: Dietary and psychological status contributes to the development of coronary artery disease. However, these lifestyle factors may vary depending on ethnic and environmental background, and secondary prevention programs dealing with these factors in a specific population are not well-established. We aimed to assess dietary and psychological characteristics in Korean patients with acute coronary syndrome (ACS) and analyze their interactions as independent risk factors for ACS.

The Association of Family History of Premature Cardiovascular Disease or Diabetes Mellitus on the Occurrence of Gestational Hypertensive Disease and Diabetes.

Background: Gestational hypertensive diseases (GHD) and gestational diabetes mellitus (GDM) increase the risk of cardiovascular disease (CVD) later in life. However, the association between gestational medical diseases and familial history of CVD has not been investigated to date. In the present study, we examined the association between familial history of CVD and GHD or GDM via reliable questionnaires in a large cohort of registered nurses.

Poor health-related quality of life and proactive primary control strategy may act as risk factors for acute coronary syndrome.

Background And Objectives: Increasing evidence supports that psychological factors may be related to development of coronary artery disease (CAD). Although psychological well-being, ill-being, and control strategy factors may play a significant role in CAD, rarely have these factors been simultaneously examined previously. We assessed comprehensive psychological factors in patients with acute coronary syndrome (ACS).

Immobilization stress induces endothelial dysfunction by oxidative stress via the activation of the angiotensin II/its type I receptor pathway.

Objective: Psychological stress has been shown to contribute to the development of atherosclerosis; however its underlying mechanism has not been clearly elucidated. We here studied the mechanism by which immobilization stress causes endothelial dysfunction with specific aim of identifying the role of angiotensin II and its type I (AT(1)) receptor signaling pathway.

Methods And Results: Rats (n=30) were subjected to immobilization stress (120 min/day) for 14 days using a restrainer.

Blockade of TGF-β by catheter-based local intravascular gene delivery does not alter the in-stent neointimal response, but enhances inflammation in pig coronary arteries.

Background: Extracellular matrix (ECM) accumulation significantly contributes to in-stent restenosis. In this regard, transforming growth factor (TGF)-β, a positive regulator of ECM deposition, may be implicated in in-stent restenosis. The goal of this study was to assess the effect of blockade of TGF-β on stent-induced restenosis in porcine coronary arteries.

Catheter-based adenovirus-mediated local intravascular gene delivery of a soluble TGF-beta type II receptor using an infiltrator in porcine coronary arteries: efficacy and complications.

Enhanced extracellular matrix (ECM) accumulation is an important finding in human restenotic arterial neointima after angioplasty. Transforming growth factor beta1(TGF-beta1) is known to regulate the synthesis and turnover of a variety of ECM components, and may play an important role in restenosis. Recombinant adenoviral vector expressing an ectodomain of the TGF-beta type II receptor fused to the human immunoglobulin Fc portion (AdTbeta-ExR) inhibits the action of TGF-beta probably either by adsorbing TGF-beta or by acting as a dominant negative receptor.

Enhanced extracellular matrix accumulation in restenosis of coronary arteries after stent deployment.

Objectives: The goal of this study was to evaluate the cellular and extracellular composition of human coronary arterial in-stent restenosis after various periods of time following stent deployment.

Background: Neointimal in-growth rather than stent recoil is thought to be important for coronary arterial in-stent restenosis. There is only limited data on the cellular and extracellular composition changes with time after stent deployment.
