Summary
Pleural mesothelioma can mimic cardiac events like ST elevation, leading to misdiagnosis. Early clinical assessment and noninvasive imaging are crucial for accurate diagnosis and patient management.
Area of Science:
- Cardiology
- Oncology
- Thoracic Surgery
Background:
- Pleural mesothelioma is a rare and aggressive cancer.
- Chest pain and ST elevation are common presentations of acute coronary syndrome.
- The urgency of percutaneous coronary intervention can sometimes lead to diagnostic challenges.
Observation:
- A 59-year-old male with pleural mesothelioma presented with chest pain and ST elevation.
- Coronary angiography ruled out acute coronary occlusion.
- High-resolution CT revealed pericardial tumor infiltration and inflammation.
Findings:
- The patient's symptoms were caused by pericardial involvement of mesothelioma, not a primary cardiac event.
- Diagnostic confusion arose due to the overlap of symptoms with acute coronary syndrome.
- Computed tomography was key in identifying the true cause of the patient's presentation.
Implications:
- Clinical evaluation in emergency settings requires careful consideration of differential diagnoses beyond the most time-sensitive conditions.
- Noninvasive imaging modalities are vital for accurate diagnosis in complex presentations.
- Integrating oncological and cardiac assessments can improve patient outcomes in cases of mesothelioma with cardiac-like symptoms.

01:29Angina 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...
01:19Acute 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...
01:30Acute 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...
01:30Acute 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...
01:27Angina II: Classification
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...
01:17Imaging 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...
