Summary
Subarachnoid hemorrhage can mimic a heart attack. This rare case highlights how brain bleeding can present with ST elevation myocardial infarction symptoms, leading to misdiagnosis.
Area of Science:
- Cardiology
- Neurology
- Radiology
Background:
- ST elevation myocardial infarction (STEMI) is a critical cardiac condition characterized by ECG changes, abnormal heart wall motion, and elevated cardiac markers.
- Subarachnoid hemorrhage (SAH) is a type of stroke caused by bleeding in the space surrounding the brain, often due to aneurysm rupture.
Observation:
- A 50-year-old woman presented with classic ECG findings suggestive of STEMI, including anterior wall motion abnormalities and elevated cardiac biomarkers.
- Cerebral CT scan revealed a ruptured distal internal carotid artery aneurysm, causing subarachnoid and intraventricular hemorrhage.
Findings:
- The patient's cardiac symptoms and diagnostic findings were ultimately attributed to a subarachnoid hemorrhage, not an acute myocardial infarction.
- This case illustrates a rare clinical presentation where neurological emergency mimics a cardiovascular emergency.
Implications:
- Clinicians must consider non-cardiac causes, such as subarachnoid hemorrhage, in the differential diagnosis of patients presenting with STEMI-like symptoms.
- Early recognition and appropriate diagnostic workup are crucial to avoid misdiagnosis and ensure timely treatment for both neurological and cardiac conditions.

1.4K
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...

1.1K
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
