Duration Analysis for Coronary Artery Disease Patients With Chronic Chest Pain: An Output From Saudi Arabia

Abstract

Introduction: Coronary artery disease (CAD) is a persistent public health problem worldwide. Chest pain is one of the perceptible symptoms of the same disease. Literature has found acute chest pain as plausible risk factors for CAD. Nevertheless, none of the study has estimated duration from chronic chest pain to the diagnosis of CAD. The objective of the study was to estimate duration from chronic chest pain to CAD and to assess impact of risk factors on same duration. Methods: Data were obtained from community based study on 17,232 Saudi adults. History of patients about onset of chest pain and other risk factors were inquired. Descriptive measures were obtained by Kaplan-Meier curve. Effect of demographic and clinical factors was assessed by Cox regression models. Results: Out of 24% patients with chest pain, 21% diagnosed with CAD. The average duration was 5 years. About 12% of patients with chest pain diagnosed with CAD after one year. Advancing age, female gender, no exercise and reduced high density lipoprotein (HDL) were significantly hazardous predictors throughout duration from chest pain to diagnosis of CAD. Conclusion: The duration from chest pain to CAD was 5 years. Age, gender, exercise and HDL can be variables of concern to deteriorate hazards of CAD for patients with chest pain.

Risk factors of coronary heart disease patients at Misrata: Awareness and orientation

“…The performance of the physical exercise, very few patients had performed daily, were 9%, compared with who were exercise occasionally 54%, thus was shown in table (5). The highest percentage of patients had practiced a sedentary lifestyle.…”

“…According to earlier research, the prevalence of coronary heart disease (CHD) has increased by 160% across the Middle East and North Africa, and the condition has a high mortality rate (120 per 100,000 people). Similar to Tunisia, where research shows that between 1997 and 2009, the mortality rates from coronary heart disease (CHD) increased by 11.8% for men and 23.8% for women [5].…”

“…Many of the risk factors of CHD such as Diabetes Mellitus (DM), dyslipidemia, hypertension (HTN), physical inactivity, and smoking are prevalent in Libya [4,5]. This places Libya at risk for developing CHD, which is the leading cause of their mortality.…”

Chest Pain

“…Advancing age, female sex, no exercise, and reduced HDL are significantly hazardous predictors throughout the duration from CP to diagnosis of CAD [11]. Age, sex, exercise, and HDL can be variables of concern to deteriorate hazards of CAD in patients with CP.…”

“…The most common condition and cause of death in the developed world is coronary artery disease (CAD) [1]. Around the world, prevalence of CAD is 10 % [2], and in Pakistan, it is approximately 17 % [3,4]. The pathogenesis of CAD is complicated and includes endothelial cells (ECs) dysfunction, cholesterol uptake, chronic inflammatory reactions, and vascular smooth muscle cell (VSMC) proliferation.…”
