Impact of Narrative Nursing and Cognitive Behavioral Rehabilitation on Cognitive Function and Anxiety in Patients With Alzheimer's Disease.

Cardiovascular diseases (CVDs) encompass a range of disorders affecting the heart and blood vessels, standing as a formidable global health challenge and a leading cause of death worldwide []. In 2019 alone, CVDs claimed the lives of approximately 17.9 million individuals, representing a staggering one-third of total global mortality [, ]. Predominantly, ischemic heart disease, stroke, heart failure (HF), cardiomyopathy, and atrial fibrillation (AF) collectively contribute to over 95% of cardiovascular disease-related deaths []. The increasing prevalence of CVDs is exacerbated by demographic shifts, particularly the aging of the global population, playing a pivotal role in optimal cardiovascular system function []. Additionally, a myriad of risk factors, including unhealthy diet, physical inactivity, tobacco use, alcohol consumption, gender, genetic determinants, and disorders of lipid metabolism, contribute to the rising incidence of CVDs []. These risk factors manifest as elevated blood pressure (hypertension), increased blood glucose (diabetes), raised blood lipids (dyslipidemia), or present as obesity [, ]. These intermediate risk factors collectively serve as indicators for evaluating the risk of heart attacks, strokes, heart failure, and other complications associated with CVDs []. In the traditional approach to CVD risk assessment, measurements of serum lipid profile levels have played a crucial role [, , ]. The National Cholesterol Education Program (NCEP) continues to prioritize low-density lipoprotein cholesterol (LDL-C) as a primary target for lipid-lowering therapy in the context of cardiovascular diseases []. A cohort study of 12.8 million adults found that the lowest all-cause mortality occurred at total cholesterol levels of 210–249 , except for specific age-gender groups []. Similar findings from the British Heart Foundation and the World Health Organization, dating back to 2005, showed that optimal total cholesterol concentrations ranged between 200 and 240 for lowest all-cause mortality, with the lowest mortality from cardiovascular diseases occurring at approximately 190–225 [].
