Sudden cardiac arrest (SCA) is a life-threatening condition that occurs when the heart suddenly stops beating. It is a medical emergency that requires immediate intervention to prevent death.

While both men and women are at risk of experiencing SCA, studies have consistently shown that women are less likely to survive compared to men. This article delves into the reasons behind the disparity and looks at various factors contributing to why women don’t survive SCA as often as men.

Gender Differences in Symptoms

One of the major reasons women might be less likely to survive SCA is due to gender differences in symptoms. In many cases, women experience atypical symptoms or are more likely to dismiss warning signs.

Unlike the classic symptom of chest pain typically associated with heart attacks in men, women may present with subtler indications such as shortness of breath, nausea, jaw pain, or back pain. These differences in symptoms often result in delayed recognition and diagnosis of SCA in women, reducing their chances of survival.

Delay in Seeking Medical Help

Alongside atypical symptoms, women also tend to delay seeking medical help when they experience warning signs of heart issues.

This delay in recognizing the severity of symptoms can be attributed to various factors including societal expectations, self-neglect, or simply underestimating the risk of heart disease. As a result, women may not receive timely medical intervention, leading to a worse prognosis and lower survival rates.

Hormonal Factors

Hormonal factors also play a role in the differences in survival rates between men and women during sudden cardiac arrest. Estrogen has been shown to have a protective effect on the heart, reducing the risk of heart disease in premenopausal women.

However, after menopause, estrogen levels decline, increasing the risk of cardiovascular problems. Additionally, hormonal fluctuations during the menstrual cycle may affect heart electrical activity, potentially contributing to the higher vulnerability of women to certain arrhythmias that can lead to SCA.

Underdiagnosis and Misdiagnosis

Underdiagnosis and misdiagnosis of heart disease in women contribute to the lower survival rates following SCA. Traditionally, heart disease has been predominantly associated with men, leading to a bias towards male-specific symptoms and risk factors.

As a result, women are often overlooked or misdiagnosed, leading to delayed treatment. It is crucial for healthcare professionals to recognize the unique symptoms and risk factors linked to cardiac issues in women to ensure appropriate and timely interventions.

Psychosocial Factors

Psychosocial factors also affect the survival rates of women during sudden cardiac arrest.

Women often take on multiple roles and responsibilities, and the stress associated with balancing work, family, and societal expectations can impact their overall health. Chronic stress has been linked to an increased risk of heart disease and can worsen outcomes in the event of SCA.

The societal pressure on women to prioritize others’ needs before their own health may also contribute to delayed medical help-seeking and subsequent poorer survival rates.

Underrepresentation in Clinical Trials

Another significant factor impacting the gender disparity in SCA survival rates is the underrepresentation of women in clinical trials and research studies.

Historically, women have been excluded or underrepresented in clinical trials, resulting in a lack of understanding of appropriate treatment strategies specific to women. This gender bias in research limits the development of effective therapies and interventions tailored for women’s unique cardiovascular needs, potentially leading to worse outcomes during SCA.

Cardiopulmonary Resuscitation (CPR) Knowledge and Training

Women also face challenges related to cardiopulmonary resuscitation (CPR) knowledge and training, which can impact survival rates during SCA. Studies have shown that women are less likely to receive immediate bystander CPR compared to men.

This discrepancy may be due to societal perceptions, fear of causing harm, or lack of confidence in performing CPR on women. Enhancing CPR education and raising awareness about how to respond during cardiac emergencies in women can help bridge this gender gap and improve survival rates.

Impact of Underlying Health Conditions

The presence of underlying health conditions can significantly influence the survival rates of women during sudden cardiac arrest. Certain conditions, such as diabetes and hypertension, are associated with an increased risk of heart disease and SCA.

Women with these comorbidities may already have compromised heart function, leading to a higher likelihood of death following SCA. Proper management and early detection of these conditions are crucial in reducing the risk and improving survival outcomes in women.

Age-related factors also contribute to the differences in survival rates between men and women during sudden cardiac arrest. Studies indicate that elderly women are at a higher risk of poor outcomes following SCA compared to elderly men.

Age-related changes in the cardiovascular system, coupled with other comorbidities, may make it more challenging for older women to recover from cardiac events. Age-appropriate interventions and specialized care for elderly women are essential to improve survival rates.

Interaction between Genetics and Environment

The interaction between genetics and environmental factors also contributes to the gender disparity in SCA survival rates. Genetic variations can affect the risk of developing heart disease and may influence the response to medical interventions.

Women may possess different genetic variants or hormonal influences that increase their susceptibility to adverse cardiac events. Understanding the interplay between genetics and environmental factors is crucial for developing personalized treatment approaches and improving survival rates among women.

Conclusion

Sudden cardiac arrest is a serious medical condition that requires prompt intervention to increase the chances of survival.

Unfortunately, women tend to have lower survival rates compared to men, mainly due to various factors such as atypical symptoms, delay in seeking medical help, hormonal influences, underdiagnosis, psychosocial factors, underrepresentation in research, lack of CPR knowledge, underlying health conditions, age-related factors, and genetic and environmental interactions. By addressing these factors and raising awareness, healthcare providers can work towards narrowing the gender gap in sudden cardiac arrest survival rates and improving outcomes for women.
