Cardiovascular disease is the leading cause of death for women in Canada, yet it's often under-recognized and under-diagnosed. This isn't due to a lack of symptoms, but often because the symptoms themselves present differently than the "classic" heart attack picture, leading to delays in diagnosis and treatment.
Beyond the chest pain: how heart disease presents in women
When you picture a heart attack, you might imagine someone clutching their chest in sudden, severe pain. While this can happen to women, it's far less common. Instead, women often experience more subtle, diffuse symptoms that can be easily dismissed or attributed to other causes. These can include persistent fatigue that isn't relieved by rest, unexplained nausea or indigestion, discomfort in the jaw or upper back that can feel like a dull ache or pressure, and breathlessness that occurs with less exertion than usual. Some women report feeling lightheaded or dizzy, or experiencing pain in one or both arms, not just the left.
These symptoms are just as serious as chest pain, but their less dramatic nature means they are sometimes overlooked by both patients and healthcare providers. Recognizing these alternative presentations is crucial for timely intervention.
Pregnancy history: a window into future heart risk
Your pregnancy history isn't just about the health of your baby; it provides valuable insights into your long-term cardiovascular health. Conditions like gestational diabetes, pre-eclampsia, and other hypertensive disorders of pregnancy significantly increase your risk of developing heart disease and type 2 diabetes decades later. For example, a history of pre-eclampsia can double a woman's risk of heart attack or stroke later in life. Gestational diabetes similarly elevates the risk of developing type 2 diabetes, which is a major risk factor for heart disease.
When you're discussing your health with a clinician, it's important to proactively share these details, even if the pregnancies were many years ago. This information helps create a more complete picture of your personal risk factors, allowing clinicians to recommend appropriate screening and preventive strategies.

PCOS and early menopause: explicit risk factors
Two other significant factors in women's health that directly impact cardiovascular risk are Polycystic Ovary Syndrome (PCOS) and early menopause. PCOS is a common hormonal disorder that often involves insulin resistance, higher androgen levels, and inflammation, all of which contribute to an increased risk of heart disease, even in younger women. Similarly, entering menopause before the age of 40 or 45 (early menopause) removes the protective effects of estrogen sooner, leading to a faster progression of cardiovascular risk factors.
Because these conditions are so impactful on heart health, it is vital to explicitly mention them during any health assessment, even if they don't seem directly related to the current discussion. Clinicians need this information to accurately assess your risk and tailor prevention strategies.

Weight's role among other levers
While often a focus, the number on the scale is just one piece of the puzzle when it comes to heart health. It interacts with and influences other critical risk factors: blood pressure, blood lipids (cholesterol and triglycerides), blood glucose levels, smoking status, and physical activity. Each of these is an independent lever that can be adjusted to improve your cardiovascular profile, regardless of your current weight.
For instance, managing high blood pressure through lifestyle changes or medication can significantly reduce heart risk, even if weight loss is minimal. Similarly, improving lipid profiles or achieving better blood glucose control directly benefits heart health. Smoking cessation is one of the most impactful changes you can make. Regular physical activity, even without significant weight loss, strengthens the heart and improves overall metabolic health. Focusing solely on weight without addressing these other modifiable risk factors misses a crucial opportunity for comprehensive cardiovascular protection. Our page on blood pressure, lipids and weight: the risk you can actually move offers further insights into these interconnected factors.
Navigating Canadian risk assessment: asking for what you need
In Canada, a standard cardiovascular risk assessment typically involves reviewing your medical history, family history of heart disease, and lifestyle factors like smoking, diet, and physical activity. Your healthcare provider will also likely measure your blood pressure, and order blood tests to check your cholesterol levels (including LDL, HDL, and triglycerides) and blood sugar (HbA1c or fasting glucose).
Based on these factors, clinicians often use risk calculators like the Framingham Risk Score or the Canadian Cardiovascular Society guidelines to estimate your 10-year risk of a cardiovascular event. However, these tools may not always fully capture the unique risk factors women face, such as those related to pregnancy or specific hormonal conditions mentioned above.
If you have concerns about your heart health, or if you have any of the specific risk factors discussed (e.g., history of gestational diabetes, pre-eclampsia, PCOS, or early menopause), don't wait to be offered a comprehensive assessment. Be proactive. Schedule an appointment with your family doctor and explicitly ask for a cardiovascular risk assessment. Clearly state your concerns and provide all relevant history, especially those unique to women's health. This ensures your clinician has the complete picture to assess your risk accurately and discuss appropriate preventive strategies.

Common questions
Are heart attack symptoms different in women?
Yes, heart attack symptoms in women are often different from the "classic" chest-clutching pain. While some women do experience chest pain, it's more common to have symptoms like unusual fatigue, nausea, shortness of breath, or discomfort in the jaw, neck, back, or arms. These symptoms can be less dramatic and may be mistaken for other conditions, leading to delays in seeking care.
Does pregnancy history affect heart risk later?
Absolutely. Pregnancy complications like gestational diabetes, pre-eclampsia, and other high blood pressure disorders during pregnancy are strong predictors of increased cardiovascular risk decades later. It's crucial to share this history with your healthcare provider, even if it happened many years ago, as it helps them assess your long-term heart health risk more accurately.
Does losing weight lower heart risk on its own?
While losing weight can significantly contribute to lowering heart risk, it's not the only factor and doesn't work "on its own." Heart risk is influenced by multiple interconnected factors including blood pressure, cholesterol levels, blood glucose, smoking, and physical activity. Weight loss can positively impact these other factors, but independently addressing each of them through lifestyle changes and, if necessary, medication, provides a more comprehensive approach to reducing heart risk.
