Young Women Having Heart Attacks: In a surprising revelation, a groundbreaking study by the Mayo Clinic has uncovered that over 50% of heart attacks in women under the age of 65 are not caused by the traditional culprit of blocked arteries. Instead, these heart attacks stem from lesser-known conditions that are often overlooked by both patients and healthcare professionals.
Since the COVID-19 pandemic, there has been an alarming rise in heart attack cases, not just among older adults but also in younger individuals, particularly women. For decades, medical teachings have emphasized that heart attacks primarily result from atherosclerosis — the buildup of plaque in the arteries. However, this new study suggests that this conventional understanding may not always apply, especially to younger women.
The Mayo Clinic’s 15-year comprehensive study reveals a startling reality: many heart attacks in women under 65 are due to conditions other than artery blockage. These findings are significant because they point toward the urgent need for tailored diagnostic and treatment strategies that address these underappreciated causes.
What Is SCAD? A Lesser-Known Cause of Heart Attacks
Understanding SCAD
Spontaneous Coronary Artery Dissection (SCAD) is one of the most surprising culprits behind heart attacks in young women. In SCAD, the inner wall of a heart artery suddenly tears or ruptures, disrupting normal blood flow to the heart. This reduction in oxygen supply can lead to a heart attack, even in women with no traditional heart disease risk factors.
Shockingly, SCAD tends to affect otherwise healthy women, often between the ages of 30 and 50, and is frequently misdiagnosed as a typical heart attack caused by plaque buildup. Misdiagnosis can lead to inappropriate treatments, such as unnecessary stenting or aggressive interventions that may worsen the condition.
Why Are Young Women More at Risk?
Hormonal fluctuations, especially during pregnancy and postpartum periods, along with genetic predispositions, are major contributors to SCAD risk. These factors make SCAD a unique and dangerous condition that requires specific attention during diagnosis and treatment.
Other Non-Traditional Causes of Heart Attacks
Coronary Embolism
A coronary embolism occurs when a blood clot or foreign object blocks one of the heart’s arteries. Unlike typical plaque-based blockages, these embolisms may arise due to clotting disorders, certain infections, or other systemic health issues.
Infections and Anaemia
Both infections and severe anaemia place additional stress on the cardiovascular system, potentially triggering heart attacks in vulnerable individuals. The Mayo Clinic study found that these conditions are often overlooked in standard heart attack diagnoses, especially in younger women without obvious risk factors.
Why These Findings Matter
Historically, heart attack treatments have revolved around the assumption that atherosclerosis is the primary cause. However, the Mayo Clinic study shows that young women frequently experience heart attacks due to SCAD, coronary embolism, or systemic factors. Treating these conditions under the assumption they are traditional plaque blockages may lead to misdiagnosis or harmful interventions.
Dr. Aditya Kelkar of NIO Super Specialty Hospital emphasizes, “The study highlights that healthcare professionals should investigate the specific causes of heart attacks in young women and adjust treatment protocols accordingly. Conservative management may be the best approach in cases like SCAD, rather than stent placement.”
Moreover, the study also reports that heart attacks caused by non-plaque factors tend to have higher five-year mortality rates, making early and correct diagnosis even more crucial.

How to Protect Yourself
1. Know the Symptoms
Young women should be vigilant for atypical heart attack symptoms, such as:
- Sharp chest pain or discomfort
- Shortness of breath
- Unexplained fatigue
- Dizziness or fainting
- Pain in the neck, jaw, or back
2. Regular Medical Check-Ups
Routine cardiovascular check-ups, especially for women with a family history of heart disease, high blood pressure, or hormonal fluctuations, can help detect risk factors early.
3. Manage Lifestyle Factors
- Maintain a healthy diet low in processed fats and sugars
- Engage in regular physical activity
- Manage stress levels through mindfulness or therapy
- Avoid smoking and limit alcohol intake
4. Consult Specialized Cardiologists
If experiencing unusual heart symptoms, consult a cardiologist experienced in managing SCAD and other non-plaque-related conditions.

Conclusion
The Mayo Clinic’s study is a wake-up call for both healthcare providers and young women across the globe. It challenges the long-held belief that blocked arteries are the primary cause of heart attacks in younger women. Instead, conditions like SCAD, coronary embolism, and systemic factors such as infections and anaemia play a significant role in this rising health concern.
By raising awareness about these findings, the medical community can shift toward more precise diagnostic practices and personalized treatment plans. Early detection remains the most powerful defense against life-threatening complications, especially in a demographic that often underestimates its vulnerability to heart disease.
Young women must not ignore unusual symptoms and should prioritize regular medical check-ups to safeguard their heart health. With the right knowledge, preventive strategies, and timely medical intervention, these silent threats can be managed effectively, preserving quality of life and reducing mortality risks.
FAQs Young Women Having Heart Attacks
1. What is Spontaneous Coronary Artery Dissection (SCAD)?
SCAD is a condition where the inner wall of a coronary artery tears, restricting blood flow and causing a heart attack. It often affects young, otherwise healthy women and is frequently misdiagnosed due to the absence of traditional risk factors like high cholesterol.
2. Why are young women increasingly experiencing heart attacks?
Hormonal fluctuations, genetic predisposition, and lifestyle factors such as stress and poor diet contribute significantly. The COVID-19 pandemic has also worsened underlying health issues, resulting in a sharp rise in heart attack cases among young adults.
3. How is SCAD treated differently from regular heart attacks?
Unlike plaque-induced heart attacks where stents are commonly used, SCAD often requires conservative management to avoid worsening the tear. Treatment focuses on monitoring, managing blood pressure, and avoiding invasive procedures unless absolutely necessary.
4. Can lifestyle changes prevent these non-plaque-related heart attacks?
Yes. Maintaining a balanced diet, exercising regularly, managing stress, and avoiding smoking can lower the risk of SCAD and other non-traditional heart attack causes. Early screening and management of conditions like high blood pressure or anaemia are also critical.
5. What should I do if I suspect a heart attack?
Seek medical attention immediately if experiencing symptoms like chest pain, shortness of breath, dizziness, or jaw pain. Early consultation with a cardiologist specializing in SCAD and other atypical causes is essential for accurate diagnosis and treatment.
