Many of the tools, systems, and models used to assess cardiovascular health in modern medicine were originally built using data gathered primarily from men. Over time, research has begun to reveal that this approach left important gaps in how we understand heart disease in women.

As new studies emerge—and as long-standing but often overlooked data is revisited—we are beginning to see a clearer picture. Cardiovascular disease in women does not always follow the patterns many clinicians were originally trained to recognize.

As a paramedic and firefighter responding to medical emergencies, I began noticing how often these differences appeared in real life. Women would describe symptoms that didn’t quite fit the traditional narrative we were taught to look for.

That realization led me to start asking deeper questions and exploring the research more closely. What I discovered is that the story of women’s heart health is still being written, and there is much more we are beginning to understand.

My hope is to share some of what I have learned so that more women can better understand their heart health, recognize potential warning signs earlier, and feel confident seeking answers when something doesn’t feel right.

What Research is Showing:

• Cardiovascular disease has been the leading cause of death among women for decades.

• Up to 78% of heart attack symptoms in women may go unrecognized.

For many years, the medical community relied on a “standard” picture of heart disease that was largely based on how it appears in men.

But as research expands, we are learning that women often experience heart disease differently.

Symptoms such as unusual fatigue, nausea, shortness of breath, back pain, or jaw discomfort may not immediately be recognized as cardiac in origin. Because of this, studies suggest that many heart attack symptoms in women go unrecognized.

This doesn’t mean healthcare providers aren’t trying to help. In many cases, it simply reflects the limitations of the data and training that shaped earlier medical understanding.

As new research continues to emerge, we are beginning to close that gap.

• Less than 30% of cardiovascular research focuses on women, and very little focuses on prevention.

When we look at the research itself, another pattern appears.

For many years, cardiovascular studies included far more male participants than female ones. Even today, a relatively small portion of cardiovascular research focuses specifically on women.

That doesn’t mean doctors aren’t trying to help. It simply means that some of the knowledge we rely on was built from incomplete data. As new research emerges, we’re beginning to see a clearer picture of how heart disease develops and appears in women.

• More than half of heart attacks in women may be ‘silent’, meaning no symptoms and almost as many are non-flow limiting stenosis; no blockages

Emerging research is also helping us understand why heart disease in women can be harder to detect early.

A large portion of heart attacks in women can occur without the dramatic symptoms many people expect. In some cases there may be no major arterial blockage at all, but rather inflammation, small-vessel disease, or other mechanisms that don’t show up clearly on traditional tests.

This helps explain why some women know something feels wrong long before a diagnosis is made.
