The Canadian Cardiovascular Society (CCS) Grading System classifies angina pectoris severity based on the frequency, duration, and intensity of chest pain. Grade I indicates mild angina that occurs with strenuous activity; Grade II describes moderate angina that arises with ordinary physical activity; Grade III involves severe angina that occurs with minimal exertion or at rest;…
The coronary sinus ostium is the opening of the coronary sinus, a large vein that collects deoxygenated blood from the heart before draining it into the right atrium. It is located at the junction of the left atrial appendage and the inferior vena cava, and receives blood from the great, middle, and small cardiac veins….
CCS class angina refers to a classification system used to assess the severity of stable angina, which is a type of chest pain caused by reduced blood flow to the heart. Class I angina is characterized by mild pain or discomfort that occurs with strenuous or prolonged exertion. Class II angina involves more frequent pain…
“Corona Pre Treatment” is not mentioned in the provided text, so I cannot extract the requested information. The Key Players in the COVID-19 Response: Health Organizations When the COVID-19 pandemic hit, a whole army of health organizations sprang into action, ready to battle this microscopic foe. Among them were some familiar names and some you…
Corona discharge treatment, a surface modification technique, utilizes ionization to enhance material properties. Leading manufacturers provide equipment with varying capabilities and specialties. Suppliers offer essential materials, while research institutions explore novel applications and advancements. These entities collaborate to refine the technology and expand its industrial uses. Meet the Titans: Manufacturers of Corona Discharge Equipment In…
The diagonal coronary artery, a branch of the left coronary artery, descends diagonally in the anterior interventricular sulcus. It supplies blood to the anterior and lateral walls of the left ventricle. Variations in its origin and course are common. Pathological variations include occlusion due to atherosclerosis, causing myocardial ischemia or infarction. Diagnostic techniques include angiography,…
Three vessel coronary disease (3VD) is a severe form of coronary artery disease where blockages occur in three of the major coronary arteries that supply blood to the heart. It can lead to significant heart muscle damage and increased risk of heart attack. Symptoms may include chest pain, shortness of breath, and fatigue. Diagnosis involves…
A dilated coronary sinus, scored between 8-10, is often associated with congenital heart defects such as Atrial and Ventricular Septal Defects, or Tetralogy of Fallot. It can also be linked to cardiovascular diseases like Coronary Artery Disease, Myocardial Infarction, and Heart Failure. Various diagnostic imaging techniques, including Echocardiography, Cardiac Catheterization, and Cardiac Magnetic Resonance Imaging,…
Crease in Earlobe Heart Disease A diagonal crease or wrinkle in the earlobe, known as the Frank sign, can indicate an increased risk of coronary artery disease (CAD). The presence of this crease correlates with a narrowing of the carotid arteries, which supply blood to the brain, and an increased thickness of the intima-media layer…
An unroofed coronary sinus is a rare congenital heart defect characterized by the absence of the posterior wall of the coronary sinus, exposing the atrial myocardium. It can occur as an isolated anomaly or in association with other cardiac defects, such as atrial septal defects and Ebstein’s anomaly. The unroofed coronary sinus allows blood to…
Right coronary dominance is a variation in coronary artery anatomy where the right coronary artery (RCA) is larger than the left coronary artery (LCA) and supplies blood to a greater portion of the heart. This dominance occurs in about 60-80% of the population and is typically considered normal. However, in some cases, right coronary dominance…
Acute coronary syndrome (ACS) in Australia is a broad term encompassing various conditions, including non-ST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardial infarction (STEMI). ACS occurs when there is a sudden reduction or blockage in blood flow to the heart, resulting in chest pain (angina) and other symptoms like shortness of breath. Prompt medical attention is…
