Insights

The left anterior descending artery is the most common coronary artery affected in myocardial infarction patients in Najran, KSA. This finding is crucial for understanding coronary artery disease (CAD) in the region.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Coronary artery disease (CAD) is a leading cause of cardiovascular disease (CVD) globally.
  • Myocardial infarction (MI) represents a critical manifestation of CAD.
  • Understanding the specific patterns of coronary artery occlusion is vital for regional healthcare strategies.

Purpose of the Study:

  • To identify the primary coronary arteries occluded in patients experiencing myocardial infarction.
  • To analyze the clinical and angiographic characteristics of these patients in Najran, Kingdom of Saudi Arabia (KSA).

Main Methods:

  • A retrospective cross-sectional study involving 661 MI patients from March 2020 to March 2021.
  • Inclusion criteria: patients over 15 years old, KSA residents, diagnosed with coronary artery occlusion via angiography.
  • Generalized linear mixed models were used to analyze patient data.

Main Results:

  • The study included 661 patients, with 82.9% males and 17.1% females, aged 15-85 years (mean age 55-64).
  • ST-segment elevation myocardial infarction (STEMI) was the most frequent diagnosis (55.4%), followed by non-ST-segment elevation MI (NSTEMI) (28.3%).
  • The Left Anterior Descending (LAD) artery was the most commonly occluded vessel.

Conclusions:

  • The Left Anterior Descending (LAD) artery is the most frequently affected coronary artery in patients with myocardial infarction.
  • These findings highlight the LAD's significance in MI pathogenesis within the Najran region.
  • This data can inform targeted prevention and treatment strategies for CAD in KSA.

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...
