ATRIA Stroke Risk Score: Explanation and Clinical Context The ATRIA Stroke Risk Score is a validated clinical tool to predict the risk of ischemic stroke in patients with atrial fibrillation. It uses common patient characteristics including age, sex, history of diabetes mellitus, heart failure, hypertension, and prior stroke/TIA. Scores are calculated by assigning points to each risk factor, resulting in a total scor
Atrial Pacing Burden (% Time Pacing): Explanation and Clinical Context Atrial Pacing Burden represents the percentage of time a patient’s atrium is paced by a pacemaker relative to the total number of heartbeats recorded. High atrial pacing burden has been associated with increased risk of atrial fibrillation, heart failure progression, and potentially adverse cardiovascular outcomes. Clinically, quantifying atrial p
Explanation and Clinical Context Attack rate is an epidemiologic measure used to quantify the proportion of individuals in a population who develop a condition during an outbreak period. It is commonly used in infectious disease investigations to describe the speed and extent of disease spread within a defined group. The calculation compares the number of new cases with the number of individuals who are susceptible o
AUDIT C Alcohol Use Screening Explanation and Clinical Context AUDIT C is a validated three item alcohol screening tool designed to rapidly identify patterns of drinking that may represent hazardous or harmful alcohol use. It evaluates how often a person drinks alcoholic beverages alongside the number of drinks typically consumed and how frequently episodes of heavy drinking occur. Each question contributes zero to t
AUGUSTUS Antithrombotic Strategy – Explanation and Clinical Context The AUGUSTUS randomized trial (2×2 factorial) compared apixaban versus a vitamin K antagonist and aspirin versus placebo in patients with atrial fibrillation and recent acute coronary syndrome and/or percutaneous coronary intervention who were taking a P2Y12 inhibitor. The principal findings were that apixaban (vs VKA) reduced clinically relevant ble

AVSD Surgical Mortality Score: Explanation and Clinical Context The AVSD Surgical Mortality Score is a predictive tool to estimate the risk of operative mortality in patients undergoing repair for atrioventricular septal defect (AVSD). It incorporates key preoperative variables, including age, weight, presence of Down syndrome, preoperative ventricular dysfunction, and pulmonary hypertension. The score uses a logisti
