Insights

Patients with chest pain and dynamic ECG changes showing typical angina have a high incidence of coronary artery disease (CAD). Atypical chest pain with dynamic ECG changes indicates a low likelihood of CAD.

Area of Science:

  • Cardiology
  • Emergency Medicine

Background:

  • Chest pain is a frequent emergency presentation.
  • Dynamic electrocardiogram (ECG) changes can occur in patients with chest pain.

Purpose of the Study:

  • To determine the incidence of coronary artery disease (CAD) in patients presenting with chest pain and dynamic ECG changes.

Main Methods:

  • Coronary angiography was performed on 72 patients with chest pain and dynamic ECG changes.
  • Patients were categorized based on chest pain characteristics (typical/unstable angina vs. atypical).

Main Results:

  • Of 39 patients with typical/unstable angina, 36 (92.3%) had CAD; mean age was 57.28 years.
  • Of 33 patients with atypical chest pain, only 2 (6%) had CAD; mean age was 45.15 years.
  • Younger patients and females with dynamic ECG changes were less likely to have CAD.

Conclusions:

  • Typical angina with dynamic ECG changes strongly suggests CAD.
  • Atypical chest pain with dynamic ECG changes has a low probability of CAD.
  • Dynamic ECG changes in younger patients or females may occur without underlying CAD.

Angina III: Clinical Manifestations and Assessment

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...
Electrocardiogram01:29

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...

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...

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 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...

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...
