Descrição
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:
- Prior myocardial infarction (MI) or angiographically confirmed coronary artery disease (CAD).
- 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:
- Resting Systolic Blood Pressure (SBP) ≥180 mmHg or Diastolic Blood Pressure (DBP) ≥110 mmHg at screening or visit day despite medication
- Oxygen saturation <90% at rest on room air
- Active myocarditis
- 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.

Participants assigned to the HIFT group will perform supervised high-intensity functional training using scalable, multi-joint functional movements three days per week for a total of 12 weeks. |
Participants will complete supervised high-intensity functional training consisting of scalable, multi-joint functional movements. Exercise sessions will occur approximately 3 times per week for 12 weeks and will last 40 to 60 minutes, including warm-up and cool-down. Examples of activities may include body-weight exercises, resistance training, step-ups, sit-to-stand movements, squats, lunges, modified push-ups, and core exercises. |
|
Experimental: Moderate-Intensity Continuous Training (MICT) Group
Participants assigned to the MICT group will perform supervised moderate-intensity continuous aerobic exercise three days per week for a total of 12 weeks. |
Participants will complete supervised moderate-intensity continuous aerobic exercise. Exercise sessions will occur approximately 3 times per week for 12 weeks and will last 40 to 60 minutes, including warm-up and cool-down. Examples of activities may include treadmill walking, cycling, elliptical exercise, or step-based aerobic activity. |

Sem intervenção: Control Group
Participants in this group will be asked to maintain their usual diet, usual medical care, physical activity, and lifestyle behaviors. |
