描述

Inclusion Criteria:

  • Age: ≥45 years.

  • Diagnosis of cardiovascular disease (CVD): Clinically documented by a licensed clinician in the medical record, including at least one of the following:

    1. Prior myocardial infarction (MI) or angiographically confirmed coronary artery disease (CAD).
    2. Stable angina, prior PCI/CABG, or documented myocardial ischemia on stress testing.

  • Clinical stability: On stable guideline-directed medical therapy (GDMT) for ≥2 weeks and no hospitalizations for acute cardiovascular events within the past 4 weeks.

  • For post-myocardial infarction (MI) participants: ≥4 weeks since index MI and clinically stable without ongoing ischemia.

  • Capacity and consent: Able to understand the study procedures and provide written informed consent (with interpreter support if needed).

  • Procedural feasibility: Able to undergo vascular ultrasound testing (e.g., flow-mediated dilation), pulse wave analysis/velocity, standard transthoracic echocardiography, body composition assessment, venipuncture for biomarkers, and submaximal fitness tests (e.g., 6-minute walk and handgrip).

  • Participants should be able to understand English or bring someone who speaks and understands English.

Exclusion Criteria:

  • Individuals who are not yet adults (infants, children, teenagers)

  • Pregnant women

  • Prisoners

  • Acute/unstable conditions (past 4 weeks): Acute coronary syndrome, decompensated heart failure, sustained ventricular arrhythmias, syncope of cardiac origin, or stroke/Transient Ischemic Attack (TIA).

  • Hemodynamic instability or severe uncontrolled disease:

    1. Resting Systolic Blood Pressure (SBP) ≥180 mmHg or Diastolic Blood Pressure (DBP) ≥110 mmHg at screening or visit day despite medication
    2. Oxygen saturation <90% at rest on room air
    3. Active myocarditis
    4. Active pericarditis

  • Valvular/structural heart disease likely to confound measures or increase risk: Severe aortic stenosis or severe valvular regurgitation; obstructive hypertrophic cardiomyopathy with resting Left Ventricular Outflow Tract (LVOT) gradient >30 mmHg; restrictive or constrictive physiology chronic or acute requiring urgent intervention

  • Arrhythmias that preclude accurate testing or pose risk: Rapid, uncontrolled atrial fibrillation/flutter (ventricular rate persistently >110 bpm at rest) or frequent ectopy that prevents reliable Doppler/strain or pulse-wave measurements. (Rate-controlled Atrial fibrillation (AF) is allowable if measurements are technically feasible.)

  • Recent major procedures: Major surgery, Percutaneous Coronary Intervention (PCI), or Coronary Artery Bypass Grafting (CABG) within the past 4 weeks (CABG within 8 weeks) unless cleared by the treating physician and study PI.

  • Severe non-cardiac comorbidities likely to confound vascular/endothelial markers or limit participation:

  • Active systemic infection or fever within 7 days; active autoimmune/inflammatory disease flare requiring escalation of immunosuppression in past 8 weeks.

  • Advanced renal dysfunction (eGFR <30 mL/min/1.73 m² or dialysis) or decompensated cirrhosis (Child-Pugh C).

  • Active malignancy receiving cytotoxic chemotherapy or thoracic radiation within the past 6 months (hormonal therapy permitted).

  • Contraindications to phlebotomy or vascular testing: Known severe bleeding diathesis or platelet count <50,000/μL; current therapeutic anticoagulation is permitted if clinically stable and venipuncture is not contraindicated by the treating clinician.

  • Peripheral vascular disease

  • Musculoskeletal/neurologic limitations preventing fitness testing (e.g., non-weight-bearing status, unstable orthopedic injuries) without safe alternatives.

  • Substance use or cognitive/psychiatric conditions that, in the investigator's judgment, would impair consent, adherence to pre-test restrictions, or completion of study procedures.

  • Current participation in another interventional trial that could affect vascular/endothelial outcomes (observational registries permitted).

  • Active participation in sports or exercise with 24-48 hours of testing.
