Insights

ST-segment elevation during dobutamine stress echocardiography can occur without coronary artery disease, potentially due to dobutamine-induced coronary artery spasm. This case highlights a rare but serious complication during cardiac stress testing.

Area of Science:

  • Cardiology
  • Clinical Medicine

Background:

  • Dobutamine stress echocardiography (DSE) is a common diagnostic tool.
  • ST-segment elevation during DSE typically indicates severe coronary artery disease (CAD).
  • Coronary artery spasm is a potential, though less common, cause of DSE-induced ST elevation.

Observation:

  • A 56-year-old man with no prior cardiovascular history underwent DSE.
  • The patient experienced intense precordial pain and significant 10-mm ST elevation during the procedure.
  • Urgent cardiac catheterization was performed to investigate the cause.

Findings:

  • Cardiac catheterization revealed no significant coronary artery stenoses.
  • The findings suggest the ST elevation was not due to obstructive CAD.
  • Coronary artery spasm induced by dobutamine is the suspected etiology.

Implications:

  • This case underscores the importance of considering coronary artery spasm in DSE-induced ST elevation, even without obstructive CAD.
  • It highlights a rare complication of dobutamine stress testing.
  • Further investigation into the mechanisms of dobutamine-induced coronary artery spasm may be warranted.

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...

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
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 I: Introduction01:30

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...
