CAD Consortium Score: Comprehensive Explanation and Clinical Context The CAD Consortium Score is a validated clinical tool developed to estimate the pre-test probability of obstructive coronary artery disease (>50% stenosis in at least one major epicardial vessel) in patients with stable chest pain. It replaces older prediction models such as the Diamond–Forrester model, which consistently overestimated risk in the m
Comprehensive Explanation: The Coronary Artery Disease – Reporting and Data System (CAD-RADS) is a standardized reporting framework for Coronary CT Angiography (CCTA) established by the Society of Cardiovascular Computed Tomography (SCCT) and the American College of Radiology (ACR). It categorizes the severity of coronary artery stenosis and provides consistent recommendations for patient management. Normal Values: -
About CADILLAC Risk Score: The CADILLAC (Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications) Risk Score is a validated prognostic model developed to predict 30-day and 1-year mortality in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). It incorporates seven key post-PCI parameters: age >65 years, LVEF <40%, renal
History of diabetes No Yes Smoking No Yes Family history of myocardial infarction No Yes LDL cholesterol mg/dL HDL cholesterol mg/dL Triglycerides mg/dL Systolic blood pressure mmHg PROCAM Score: Explanation and clinical context The PROCAM score is a point based algorithm developed from the Prospective Cardiovascular Munster study. The model estimates the 10 year risk of acute coronary events using age, systolic bloo
CASS Score (Coronary Artery Surgery Study): Comprehensive Explanation and Clinical Context The CASS Score was developed from the Coronary Artery Surgery Study to quantify the anatomical extent and severity of coronary artery disease (CAD) based on angiographic findings. Each major coronary vessel (Left Main, LAD, LCx, RCA) is scored according to the percentage of luminal narrowing and its prognostic weight. A higher
Comprehensive Explanation: The CHA2DS2-VASc-ACS Score is an adaptation of the original CHA2DS2-VASc risk model—initially used for atrial fibrillation—to evaluate cardiovascular and cerebrovascular risk in patients with acute coronary syndrome (ACS) or post-myocardial infarction (MI). Higher scores indicate greater burden of systemic vascular disease and increased likelihood of recurrent events or mortality after MI.
Explanation and Clinical Context This tool helps clinicians judge when clopidogrel monotherapy is appropriate after acute coronary syndromes by integrating key constructs from the twenty twenty five American Heart Association guideline on acute coronary syndromes. The guideline emphasizes that dual antiplatelet therapy with aspirin and a P2Y12 inhibitor remains the default approach for at least one year in patients w
Conventional Troponin 0 to 3 to 6 Hour Diagnostic Algorithm Explanation and Clinical Context This tool is designed for patients with suspected acute coronary syndrome in whom a conventional cardiac troponin assay is used rather than a high sensitivity assay. According to the twenty twenty five acute coronary syndrome guideline, cardiac troponin is the preferred biomarker for detection of myocardial injury and acute m
CRUSADE Bleeding Score: Explanation and Clinical Context The CRUSADE Bleeding Score is a validated clinical tool developed to estimate the risk of in-hospital major bleeding among patients who present with non ST elevation acute coronary syndromes. The score was derived from a large multicenter registry and includes clinical variables that are available at the time of presentation. These factors include hematocrit, c
