  • The Only Cardiology Practice in Northern NJ with a True Metabolic Cart

    This is a full-blown cardiopulmonary exercise test (CPET + VO₂ max + complete pulmonary function testing) that tells us exactly why you’re short of breath, how fit your heart really is, and what’s secretly holding you back.

    We use it to unlock answers no treadmill or echo alone can give:

    • Pinpoint the real cause of unexplained shortness of breath (heart? lungs? deconditioning? mitochondria?)

    • Accurately stage heart failure and predict prognosis (Peak VO₂ ≤14? We’ll know — and we’ll fight it — with optimal medical therapies or advanced heart failure therapies

    • Clear you (or optimize you) for major surgery — cardiac or non-cardiac

    • Build precision rehab plans after major surgeries, cancer therapy, or pulmonary embolism treatment

    • Supercharge athletes and weekend warriors with elite-level sports cardiology data

    • Phenotype obesity and metabolic syndrome so your primary doctor can only guess at

    • Separate cardiac limits from pulmonary limits from pure “I’m just out of shape”

    Bottom line: If you’re tired of hearing “your tests are normal” while you still can’t climb a flight of stairs — this test changes everything.

    We’re the only outpatient practice in the entire northern half of New Jersey with this capability. That means sharper answers, better outcomes, and a plan that actually fits your body.
