About Heart Matters

Making Sense of Heart Health, Together.

Heart Matters exists to give patients, families and carers the knowledge they need to ask better questions and take an active role in their care.

Our Story

Expert knowledge, clearly explained.

Heart Matters was founded by Professor Peter Barlis, an interventional cardiologist and Professor of Medicine with over two decades of clinical experience.

As more people turned to the internet for answers about their heart health, it became increasingly clear that much of the information available was incomplete, difficult to interpret, or not grounded in clinical expertise. Heart Matters was created to address this gap, a place where patients and their families can access reliable, evidence-based cardiovascular information they can genuinely trust.

At its core, Heart Matters is built on a simple belief: informed patients are better equipped to understand their condition, engage in meaningful discussions with their healthcare team, and make confident decisions about their care.

This is more than an information resource. Heart Matters is a clinically informed guide designed to explain complex topics clearly, remove unnecessary jargon, and empower individuals with the knowledge and confidence to better understand their heart health.

Our Mission

Empowering patients through knowledge.

Heart disease affects millions of people and their families. Too often, the information available is either too technical, too vague, or simply hard to find. Our mission is to change that and make world-class cardiovascular knowledge accessible to everyone, regardless of their medical background. We believe that an informed patient is a better patient, and that knowledge is one of the most powerful tools in managing heart health.

What We Stand For

🔬

Evidence Based

Every article is grounded in current clinical evidence and reviewed for accuracy. We don't publish speculation, only information you can rely on.

💬

Jargon Free

Medical language can be a barrier. We translate complex cardiology into plain English, clear enough to understand, accurate enough to trust.

❤️

Patient First

Everything we create is designed with the patient in mind, the person sitting with a new diagnosis, preparing for a procedure, or simply wanting to take better care of their heart.
