Conducting quality of life research in people with coronary artery disease in non-English-speaking countries: conceptual and operationalization issues.

Background: Health-related quality of life is an important clinical outcome to measure in patients with cardiovascular disease. International nurse researchers with limited English skills and novice cardiovascular nurse researchers face numerous challenges when conducting quality of life research because of the conceptual ambiguity of the construct and subsequent operationalization issues as well as difficulty identifying conceptual models to guide their quality of life research.

Purpose: The overall purpose of this article was to provide guidance to cardiovascular nurse researchers (using Thailand as an example) who are interested in examining quality of life in their native country but lack access to quality of life conceptual models and instruments because of language barriers.

Intra-coronary bone marrow mononuclear cell transplantation in patients with ST-elevation myocardial infarction: a randomized controlled study.

Background: Stem cell transplantation is a potential treatment to improve left ventricular ejection fraction (LVEF) after ST elevation myocardial infarction (STEMI). However, the outcomes still are controversial.

Objective: To determine the 6-month LVEF of the patients who underwent intra-coronary bone marrow mononuclear cell (BMC) transplantation in patients with STEMI compared with controlled subjects.

Feasibility and safety of intra-coronary bone marrow mononuclear cell transplantation in ST elevation myocardial infarction patients.

Background: Stem cell transplantation is a potential treatment to improve left ventricular ejection fraction (LVEF) after ST elevation myocardial infarction (STEMI). However technique and mode of transplantation, type of cells, number of cells, and when to transplant are still unknown.

Objective: To determine the feasibility and safety of bone marrow mononuclear cell (BMC) intra-coronary transplantation and 6-months results in patients with STEMI.

Short-term effects of an intensive lifestyle modification program on lipid peroxidation and antioxidant systems in patients with coronary artery disease.

The purpose of this study was to compare the short-term effects of an intensive lifestyle modification (ILM) program on lipid peroxidation and antioxidant systems in patients with coronary artery disease (CAD). Twenty-two patients in the control group continued to receive their conventional treatment with lipid-lowering drugs, whereas 22 patients in the experimental group were assigned to intensive lifestyle modification (ILM) without taking any lipid-lowering agent. The ILM program comprised dietary advice on low-fat diets, high antioxidants and high fiber intakes, yoga exercise, stress management and smoking cessation.
