About of Simon J. Stewart

Simon J. Stewart is a cardiologist based in Fremantle, WA, working from 32 Mouat St. He looks after people with a wide range of heart and blood vessel conditions, from day-to-day high blood pressure to more urgent problems that need quick care.

Most visits are about making sense of symptoms and getting a clear plan. That might include breathlessness, chest pain, palpitations, swelling in the legs, or feeling run down. In many cases, he helps patients manage long-term conditions like heart failure and high blood pressure, aiming to reduce flare-ups and improve day-to-day comfort.

Simon also treats heart rhythm issues, including atrial fibrillation. He looks at what’s going on with the heart’s timing, and works with patients to choose treatments that fit their situation. Valve problems are another big part of care. This can include aortic valve stenosis or aortic valve regurgitation, plus mitral valve stenosis or mitral valve regurgitation, and tricuspid regurgitation. At times, these problems can affect how well the heart pumps, so follow-up and careful monitoring matter.

For people with coronary and vascular issues, he may assess and manage conditions such as coronary heart disease and acute coronary syndrome. He also looks at heart muscle problems like cardiomyopathy and myocarditis. Some patients have complex pressures in the lungs or blood flow concerns, including pulmonary hypertension and cor pulmonale, where the heart and lungs are linked in the way they work together.

Simon’s clinic care can extend beyond adult heart disease as well. He supports people with congenital heart disease (CHD) and can also deal with coarctation of the aorta. In the broader family of conditions managed in cardiology, there are also situations like peripartum cardiomyopathy, plus rare metabolic and nutrition-linked issues that can affect the body’s overall balance, such as malnutrition and low sodium levels.

Alongside heart-focused care, he’s mindful that other health factors can show up in the cardiovascular system. Obesity and hypertension are common themes, and stroke is sometimes part of the bigger picture in people with heart-related risk.

His training is in cardiology, with ongoing professional development as guidelines and treatments keep evolving. Research and clinical trials aren’t listed here, but the approach stays grounded in current, practical care and regular follow-up.
