PAMI Risk Score: Comprehensive Explanation and Clinical Context The PAMI (Primary Angioplasty in Myocardial Infarction) Risk Score is a clinical tool developed to predict 30-day mortality in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). It uses seven readily available clinical variables: age, comorbidities, heart rate, systolic blood pressure,
PARIS Bleeding Risk Score: Comprehensive Explanation and Clinical Context The PARIS Bleeding Risk Score is a validated clinical tool developed to estimate the risk of major bleeding in patients undergoing dual antiplatelet therapy after percutaneous coronary intervention. It incorporates simple bedside variables that reflect age related vulnerability, hemodynamic reserve, underlying comorbidities, and previous bleedi
Comprehensive Explanation and Clinical Context: The PARIS Thrombosis Risk Score (Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients) is a clinical tool designed to predict the likelihood of stent thrombosis and major adverse cardiac events (MACE) among patients receiving dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). Variables and Scoring: The score is derived fr
Clinical Context This tool supports bedside discussion of dual antiplatelet therapy after acute coronary syndrome by explicitly contrasting ischemic protection with bleeding hazard in the first year after the event. Guideline recommendations describe dual antiplatelet therapy with aspirin plus an oral P2Y12 inhibitor for at least twelve months as the default in patients without high bleeding risk while also emphasizi
Post acute coronary syndrome secondary prevention optimisation tool explanation and clinical context This tool is designed to support a structured review of long term therapy in patients who have recently experienced an acute coronary syndrome event. The twenty twenty five acute coronary syndrome guideline emphasises that risk of recurrent events remains elevated for months to years after the index presentation and t
Explanation and Clinical Context This score is designed for patients resuscitated from cardiac arrest presenting with ST elevation myocardial infarction who achieve return of spontaneous circulation. Early prognostic insight provides clinical value in guiding revascularization timing and post arrest intensive care strategy including ventilation sedation temperature target management and hemodynamic support. Factors i
Explanation and Clinical Context This tool is designed as a structured aid for clinicians who individualize antiplatelet strategy after percutaneous coronary intervention in the setting of acute coronary syndromes. Current professional guidelines emphasize that duration and intensity of antiplatelet therapy after PCI are determined by a balance between ischemic risk related to the coronary event and stent characteris
clinical explanation Posterior myocardial infarction represents involvement of the basal inferolateral left ventricular wall usually supplied by the circumflex artery. Standard twelve lead ECG often underdetects this pattern because posterior injury current produces reciprocal ST depression in V1 V3 instead of direct elevation. For this reason posterior leads V7 V9 are recommended when posterior infarction is suspect
Explanation and Clinical Context The PURSUIT risk score was derived from a large international randomized trial of patients with unstable angina and non ST elevation myocardial infarction who received standard care with or without the glycoprotein two b three a inhibitor eptifibatide. It combines five bedside clinical features age sex worst Canadian Cardiovascular Society angina class in the preceding six weeks clini
