Sudden Cardiac Deaths in Women: Shefali Jariwala's Passing Highlights Alarming Trend

The recent and unexpected death of Indian actress Shefali Jariwala has sparked widespread concern and prompted a deeper look into the increasing incidence of sudden cardiac issues, particularly among women. While the official cause of Jariwala’s death is pending a post-mortem examination and forensic analysis, initial reports suggest cardiac arrest, a growing and alarming trend affecting seemingly healthy, middle-aged women.

The Rising Crisis of Sudden Cardiac Death

Sudden cardiac death (SCD), once considered a rare occurrence among young adults, is now becoming increasingly prevalent, especially in India. This alarming trend has captured the urgent attention of the medical community. Cardiovascular diseases are responsible for approximately 28% of all deaths in India, with nearly 10% of these deaths attributed to SCD. A concerning number of these fatalities occur in individuals between the ages of 30 and 50.

India's rapid socioeconomic changes have led to significant lifestyle shifts, including:

• Sedentary behavior
• Diets high in processed foods
• Increased tobacco use
• Elevated stress levels

These factors contribute to a surge in conditions like hypertension, obesity, diabetes, and coronary artery disease, all of which are major risk factors for SCD.

Historically, SCD has been more common in men. However, recent studies highlight the unique and often underestimated risks faced by women. Unlike men, women who experience SCD frequently have no prior diagnosis of cardiac issues. Structural abnormalities, such as myocardial scarring and ischemic heart disease, often remain undetected until post-mortem examinations.

The Silent Threat to Women in Midlife

Women in their 40s and 50s, like Shefali Jariwala, face a silent yet serious risk from underlying cardiac conditions. In younger populations, SCD is often linked to inherited or electrical disorders, including:

• Hypertrophic Cardiomyopathy
• Arrhythmogenic Right Ventricular Cardiomyopathy
• Long QT Syndrome
• Brugada Syndrome
• Catecholaminergic Polymorphic Ventricular Tachycardia

These conditions may not present any symptoms until a fatal arrhythmia occurs.

In this age group, additional factors like left ventricular hypertrophy, obesity, and myocardial fibrosis can increase vulnerability. The progression of myocardial scarring and fibrosis with age can be attributed to cumulative exposure to cardiovascular risks, repeated micro-ischemic events, and hormonal changes, particularly during the perimenopausal years.

Conditions like Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA), which are more common in younger women, often leave no traces in autopsies, making diagnosis even more challenging.

Stress also plays a significant role. Takutsobo cardiomyopathy (Broken Heart Syndrome), or stress-induced cardiomyopathy, is a major cause of SCD in women who juggle multiple responsibilities and experience high levels of emotional stress. Jariwala also faced personal struggles related to her divorce, anxiety, depression, and epilepsy, all of which can impact cardiovascular health. Psychiatric medications, particularly those that prolong the QT interval, have also been linked to an increased risk of SCD.

A Call for Gender-Specific Prevention and Awareness

Despite the severity of the problem, women are often underrepresented in preventive heart care. Symptoms like fatigue, palpitations, or breathlessness are frequently dismissed or misattributed, leading to delays in crucial intervention. Unlike heart attacks, which are caused by blocked arteries, cardiac arrest results from electrical disturbances that cause the heart to stop suddenly. Immediate CPR and defibrillation are often the only lifesaving measures, highlighting the need for early risk identification.

Medical experts are now advocating for more targeted public health strategies, including enhanced early screening tools tailored to women, particularly during perimenopause when cardiac risks increase.

Honoring a Star, Fueling a Movement

As the entertainment industry and fans mourn the loss of Shefali Jariwala, her tragic death serves as a stark reminder of an overlooked health crisis. It underscores the urgent need for systemic change in how women's heart health is addressed.

Jariwala captivated audiences with her on-screen presence. In the wake of her untimely passing, she may be remembered as a symbol of awareness, highlighting the importance of recognizing the heart’s silent signals and demanding immediate attention, investment, and action to improve women's cardiac health.
