Angina is chest pain caused by reduced blood flow to heart. Symptoms include squeezing, pressure, heaviness or tightness in chest. Pain may radiate to arms, neck, jaw, shoulder or back. Common symptoms include dizziness, fatigue, nausea and shortness of breath
Heart disease includes blood vessel, arrhythmia, congenital defects, muscle and valve conditions. Coronary artery disease results from plaque buildup in artery walls. Risk factors include age, gender, family history, smoking, unhealthy diet, high blood pressure
CAD reduces blood flow to heart muscle due to plaque buildup in arteries. Most common symptom is stable angina, chest pain during exercise. Can cause unstable angina, myocardial ischemia, and heart attack. Females experience symptoms 10 years later than males
PCI is a minimally invasive treatment for coronary artery disease. First introduced in 1977 by Andreas Gruentzig in Switzerland. Uses catheterization with stents to open narrowed arteries. Performed by interventional cardiologists in catheterization laboratories
CS is characterized by low cardiac output and sustained tissue hypoperfusion. SCAI classifies CS from preshock to extremis, with four hemodynamic states. Three phenotypes exist: non-congested, cardiorenal, and cardiometabolic
Patient presented with chest pain for 2 hours in 40-year-old smoker. ECG showed ST depression in V2-V5, ST elevation in inferior leads. Coronary angiography revealed total LAD occlusion with no right coronary stenosis. Successful PCI with drug-eluting stent implantation
