Silent Threats: The Rising Awareness of Aortic Aneurysms and Hidden Heart Disease
A recent case involving 38-year-old Katrina Sison, who discovered she had a rapidly expanding ascending aortic aneurysm while on her way to a volleyball game, highlights a growing concern: heart disease often presents without warning. Dr. Subodh Verma, a cardiac surgeon at St. Michael’s Hospital in Toronto, emphasizes the critical need for awareness and proactive health checks.
The Silent Killer: Aortic Aneurysms and Why They’re Often Missed
Aortic aneurysms, like the one Sison experienced, are a weakening and bulging of the aorta, the body’s main artery. These can be particularly dangerous because they often develop without noticeable symptoms until they reach a critical size or rupture. Dr. Verma explained that Sison’s aneurysm was “catastrophic” and rapidly growing, emphasizing the urgency of timely intervention. “Time was life for her,” he stated.
Beyond Chest Pain: Recognizing the Subtle Signs
Traditional heart disease symptoms, such as chest pain, are not always present. Tom Scherbluk, 58, experienced a sudden, agonizing episode that led to the discovery of an aortic dissection – a tear in the aorta’s inner layers. Undiagnosed high blood pressure was a contributing factor in his case. Dr. Verma notes that hypertension often lacks obvious signs, making regular check-ups crucial.
The Changing Definition of High Blood Pressure
Current Canadian guidelines, updated in 2025, define high blood pressure as at or above 130/80 mm Hg, a stricter threshold than previous recommendations. This change reflects growing evidence of increased cardiovascular risk even at these levels. A new report from the Heart and Stroke Foundation of Canada indicates that over 8.2 million Canadian adults have been diagnosed with high blood pressure.
Who is at Risk? Beyond Traditional Risk Factors
While family history and lifestyle factors play a role, heart disease can affect individuals with no apparent risk factors. Mahee Dharen Dharmalingam, 55, learned he had an aneurysm during a routine echocardiogram prompted by his family doctor. This underscores the importance of preventative screenings, even in the absence of symptoms.
The Importance of Early Detection and Vigilance
Dr. Verma stresses that heart disease can manifest in various ways, sometimes acutely, sometimes insidiously. He warns that the first sign can tragically be death. “If you suspect that you have heart disease or you have risk factors or you have a family history, attend with your family physician, attend with your specialist, you realize, get yourself evaluated,” he advises.
FAQ: Understanding Your Heart Health
- What is an aortic aneurysm? A weakening and bulging of the aorta, the body’s main artery.
- What are the symptoms of an aortic dissection? Sudden, severe pain, often described as tearing or ripping.
- What is considered high blood pressure? Currently, 130/80 mm Hg or higher.
- Can heart disease be prevented? Managing risk factors like high blood pressure, maintaining a healthy lifestyle, and regular check-ups can significantly reduce risk.
Pro Tip: Don’t ignore shortness of breath or unexplained fatigue. These can be subtle signs of underlying heart problems.
Did you know? Heart disease is a leading cause of death in Canada, but early detection and treatment can significantly improve outcomes.
This Valentine’s Day, prioritize your heart health. Talk to your doctor about your risk factors and schedule a check-up. Your heart is more than a symbol of love; it’s the foundation of life.
