Angina II: Classification01:27

Angina II: Classification

7
Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

Coronary Artery Disease III: Clinical Manifestations

13
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 III: Diagnostic Studies

10
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...

Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

30
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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations01:19

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

20
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...

Mitral Stenosis II: Clinical features and Diagnostic Tests01:23

Mitral Stenosis II: Clinical features and Diagnostic Tests

22
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Area of Science:

  • Cardiology
  • Internal Medicine

Background:

  • Silent myocardial infarction (SMI) often presents asymptomatically, leading to delayed diagnosis and treatment.
  • Risk factors for cardiovascular disease include obesity, prediabetes, hypertension, and hypercholesterolemia.

Observation:

  • A 59-year-old woman with multiple cardiovascular risk factors presented for herpes zoster follow-up.
  • She reported subjective symptoms of skipped heartbeats and heart rate fluctuations.
  • Electrocardiogram (ECG) revealed findings suggestive of SMI, including pathological Q waves.

Findings:

  • The patient was diagnosed with silent myocardial infarction.
  • Her risk factors included high BMI, prediabetes, primary hypertension, hypercholesterolemia, and herpes zoster.
  • Treatment involved continuing lisinopril, initiating atorvastatin, and lifestyle modifications.

Implications:

  • Early detection and management of SMI are crucial to prevent adverse cardiovascular events.
  • Identifying and addressing multiple cardiovascular risk factors is essential for patient outcomes.
  • Referral to cardiology for further assessment, including a stress test, is recommended for comprehensive management.
