Pneumothorax, or collapsed lung, happens when air escapes into the pleural space and compresses the lung. Learn why sudden chest pain and shortness of breath can signal this condition and how it is treated.

Aortic dissection is a life threatening tear in the body’s largest artery. Learn why sudden chest pain that radiates to the back demands immediate evaluation and rapid blood pressure control.

A heart attack occurs when a coronary artery suddenly becomes blocked, cutting off blood flow to heart muscle. Learn the symptoms, how it is diagnosed, and why rapid treatment saves lives.

An in-depth look at heart attacks from first symptom to catheterization. Learn how STEMI and NSTEMI are diagnosed using EKG changes and troponin, and how emergency treatment restores blood flow.

D-dimer is a blood test used to evaluate for dangerous blood clots such as deep vein thrombosis and pulmonary embolism. A normal result in the right patient can safely rule out clot, but an elevated value does not confirm one. Context and clinical risk matter.

Chest pain often triggers a troponin test. This cardiac biomarker detects heart muscle injury, but an elevated result does not always mean heart attack. The trend and the full clinical picture determine what it means.
