A working reference of clinical terms used across ZayedMD — written in plain English, with a physician’s eye on what actually matters at the bedside. Updated as new vocabulary lands in our coverage.

#

510(k) Clearance
The FDA regulatory pathway for medical devices that are substantially equivalent to a legally marketed predicate. The dominant route for AI/ML clinical-decision-support tools today.

A

Abdominoplasty
Surgical reshaping of the abdomen, commonly called a tummy tuck. Removes excess skin and tightens abdominal-wall muscles. Recovery is typically 6–8 weeks.
Alzheimer’s Disease
The most common cause of dementia, characterized by progressive memory loss and cognitive decline driven by amyloid and tau pathology. New research is exploring whether GLP-1 agonists could slow progression.
ATTAIN-1 Trial
The Phase 3 clinical trial of Eli Lilly’s oral GLP-1 receptor agonist orforglipron (brand name Foundayo). Reported weight-loss outcomes in 2026 that supported FDA approval as a first-in-class oral GLP-1 pill.

B

BMI (Body Mass Index)
Weight in kilograms divided by height in metres squared. The threshold most chronic-weight-management drugs (including GLP-1 agonists) are licensed at is BMI ≥30, or ≥27 with a weight-related comorbidity.

C

Cardiac Electrophysiology
The subspecialty of cardiology focused on the electrical signals of the heart and the management of arrhythmias such as atrial fibrillation. AI is increasingly used to interpret EP mapping data.
Cardiometabolic
Shorthand for the overlapping cardiac and metabolic effects of a therapy (blood pressure, lipids, glucose, weight). GLP-1 agonists are evaluated on cardiometabolic outcomes, not weight alone.
Clinical Decision Support (CDS)
Software that surfaces evidence-based guidance to clinicians at the point of care — e.g. sepsis alerts, dose checks, AI-generated differentials.

F

FDA Approval
The U.S. Food and Drug Administration’s authorization for a drug to be marketed for a specific indication. ZayedMD covers approvals affecting primary-care prescribing.
Foundayo
The brand name for orforglipron, Eli Lilly’s once-daily oral GLP-1 receptor agonist. FDA-approved in April 2026 for chronic weight management.

G

GLP-1 Receptor Agonist
A class of drugs that mimic glucagon-like peptide-1, slowing gastric emptying and stimulating insulin release. Used for type-2 diabetes and chronic weight management. Includes semaglutide, tirzepatide, and orforglipron.

I

ICD-10 Memory Decline
ICD-10 codes used to classify mild cognitive impairment (e.g. G31.84) and unspecified memory disturbance (R41.3). Important for accurate documentation and downstream referrals.

L

LLM (Large Language Model)
A neural-network architecture trained on text to predict the next token. In clinical practice LLMs are used for ambient documentation, patient-letter drafting, and decision support — with clear safety limits.

M

MRI (Magnetic Resonance Imaging)
A non-ionizing imaging modality using strong magnetic fields. Full-body MRI is increasingly marketed for preventive screening; the evidence base for routine screening in asymptomatic adults remains limited.

O

Orforglipron
A small-molecule, non-peptide oral GLP-1 receptor agonist (brand name Foundayo). First oral GLP-1 to clear Phase 3 with weight-loss and cardiometabolic outcomes competitive with injectables.

S

SELECT Trial
A landmark cardiovascular-outcomes trial of semaglutide in adults with overweight or obesity and established cardiovascular disease, demonstrating a 20% reduction in major adverse cardiovascular events.
Semaglutide
An injectable GLP-1 receptor agonist marketed as Ozempic (for type-2 diabetes) and Wegovy (for chronic weight management). The SELECT trial established cardiovascular benefit in obese non-diabetic patients.

T

Tirzepatide
A dual GIP/GLP-1 receptor agonist marketed as Mounjaro (diabetes) and Zepbound (weight management). Generally higher weight-loss efficacy than semaglutide in head-to-head comparisons.
