Justin A. Mariani is a cardiologist based at 55 Commercial Rd, Prahran, VIC 3181. He looks after people with a wide range of heart and circulation problems, from everyday issues like high blood pressure to more complex conditions that need careful follow-up.
In many cases, patients come in with symptoms such as shortness of breath, chest discomfort, palpitations, fainting or feeling light-headed. Justin also helps when heart rhythm problems are causing trouble, including atrial fibrillation, fast heart rhythms like PSVT, and slower or “off” rhythms such as sick sinus syndrome and heart block. At times, he manages people who have had more serious events like cardiac arrest, ventricular tachycardia or ventricular fibrillation, where risk and next steps need to be discussed clearly.
He also works with heart muscle and valve related problems, including cardiomyopathy and hypertrophic cardiomyopathy (HCM), as well as heart failure. For some people, the type is HFpEF, which can feel frustrating because symptoms can come and go even when the heart’s pumping looks “similar” on scans. Justin spends time going through what’s going on, what can be treated, and what daily life changes might help.
There are also situations where the heart’s lining or surrounding area needs attention. Justin treats conditions like pericarditis and constrictive pericarditis, and he assesses related concerns such as fluid build-up and ongoing inflammation. He may be involved where surgery-level follow-up is needed too, including patients who have had heart transplants, or people with rare issues such as heart tumours or Danon disease. And because blood pressure problems can be severe and hard to control, he looks after both hypertension and malignant hypertension.
Over time, Justin has built experience managing patients with long-term heart conditions, plus people dealing with sudden or worsening symptoms. His cardiology training supports him across this broad mix, and he keeps up with new research and treatment updates so care stays practical and up to date. For procedures, he can also help with options like cardiac ablation, depending on what the tests show.
