Causes of Coronary Artery Disease (CAD)
Coronary artery disease (CAD) is a leading cause of morbidity and mortality worldwide, driven by a complex interplay of genetic, environmental, and lifestyle factors. This article synthesizes the key causes of CAD based on recent research findings.
Genetic Factors and Susceptibility Loci
Genetic predisposition plays a significant role in the development of CAD. Recent studies have identified numerous genetic loci associated with increased risk. For instance, genome-wide association studies (GWAS) have pinpointed 25 new SNP-CAD associations in genes involved in cellular adhesion, leukocyte migration, atherosclerosis, coagulation, and inflammation. These findings highlight the importance of genetic factors in the pathogenesis of CAD.
Inflammation and Atherosclerosis
Inflammation is a critical factor in the development of atherosclerosis, the primary cause of CAD. Immune cells and their effector molecules accelerate the progression of atherosclerotic lesions, and the activation of inflammatory pathways can trigger acute coronary syndromes . The chronic inflammation of the arterial wall, driven by an imbalanced lipid metabolism and maladaptive immune responses, underscores the inflammatory nature of atherosclerosis.
Lifestyle and Environmental Factors
Lifestyle choices and environmental exposures significantly contribute to CAD risk. Factors such as smoking, poor diet, lack of physical activity, and excessive alcohol consumption are well-documented contributors. Additionally, rapid socioeconomic growth in developing countries has led to increased exposure to CAD risk factors like diabetes, hypercholesterolemia, and hypertension. These lifestyle and environmental factors are modifiable, making them key targets for prevention strategies.
Age and CAD in Older Adults
Age is a major risk factor for CAD, with older adults (≥80 years) being particularly vulnerable. This population often presents with multiple comorbidities, making the management of CAD more complex. A patient-centered approach that considers health status, functional ability, and patient preferences is essential for improving outcomes in older adults with CAD.
Role of Circular RNAs
Emerging research has identified circular RNAs (circRNAs) as important regulators in the pathogenesis of CAD. These noncoding RNAs influence gene function and are involved in various aspects of coronary atherosclerosis, myocardial infarction, and ischemic heart failure. Understanding the regulatory roles of circRNAs could open new avenues for molecular therapeutic targets in CAD.
Automated Detection and Diagnosis
Advancements in technology, such as the use of convolutional neural networks (CNNs) for analyzing ECG signals, have improved the accuracy and reliability of CAD diagnosis. Automated systems can differentiate between normal and abnormal ECG patterns with high accuracy, aiding clinicians in early and precise detection of CAD.
Conclusion
Coronary artery disease is a multifactorial condition influenced by genetic predisposition, inflammation, lifestyle choices, and age. Understanding these factors is crucial for developing effective prevention and treatment strategies. Continued research into genetic markers, inflammatory pathways, and innovative diagnostic tools will enhance our ability to combat this pervasive disease.
