Welcome back to Infinite Health! On today’s episode, host and cardiologist Dr. Arasi Maran dives into a topic that is both surprising and urgent: heart disease is the number one killer of women outpacing cancer, including breast cancer. Yet for most women, the risks and warning signs remain shrouded in mystery, and the medical system too often relies on research based predominantly on men.
Dr. Maran to unravels how a woman’s risk of heart disease changes dramatically across her lifespan from her very first period, through pregnancy, to perimenopause and beyond. Together, they explore why hormonal transitions are not just reproductive milestones, but critical windows that can reveal early signals of cardiovascular risk.
Whether you’re in your teens, planning a family, navigating menopause, or simply want to advocate better for the women in your life, this conversation will empower you with cutting-edge science, practical insights, and actionable steps for every stage. Heart health isn’t just a man’s issue, it’s every woman’s story. Let’s uncover what every woman needs to know, and why it’s time we all start listening to the signals our bodies are giving us.

Understanding Women’s Heart Health: Insights from Infinite Health
On this episode of Infinite Health, host and cardiologist Dr. Arasi Maran for a conversation every woman and everyone who cares about women should hear. The focus? The hidden dangers and overlooked truths about cardiovascular health across a woman’s lifespan.
Heart Disease: The Number One Killer of Women
Did you know that heart disease, not cancer, is the leading cause of death among women? Leila opened the episode with this sobering fact, emphasizing that the danger extends beyond old age: “By 2050, the American Heart Association projects more than 60% of women will have cardiovascular disease, including those in their 20s and 30s” (00:00:08, 00:00:44). Yet, most women aren’t even aware of their risk, nor that their heart health is intimately tied to hormonal milestones from puberty through menopause.
Why Women’s Hearts Are Different
For decades, medicine overlooked the biological differences between men’s and women’s hearts. As Dr. Arasi Maran eloquently stated, “Women's hearts are not smaller versions of men’s hearts. They are biologically distinct” (00:01:32). Most research and even emergency protocols have long been based on male physiology, leading to misdiagnoses women presenting with heart attacks are still more likely to be sent home with a prescription for anxiety (00:02:06).
Puberty, Menstruation, and Heart Health
Surprisingly, a woman’s cardiovascular “biography” begins at her first period. Early menarche (first period before age 11) doubles the risk of developing obesity-related high blood pressure in midlife, while irregular cycles in adolescence are linked to higher risk of coronary artery disease (00:03:36, 00:04:06). Dr. Arasi Maran urged that menstrual history be treated as a key cardiovascular biomarker and revisited at every well check (00:04:46).
Hormones, Pregnancy, and the “Ultimate Stress Test”
A woman’s reproductive years bring more vulnerabilities and warning signs. Conditions like PCOS and endometriosis both carry significant cardiovascular risk (00:08:31). The oral contraceptive pill, especially combined with smoking after age 35, substantially increases stroke risk, so honest discussions with clinicians about lifestyle and choices are vital (00:10:55).
Pregnancy, in Dr. Arasi Maran's words, is “the ultimate cardiac stress test.” Blood volume increases by almost 50%; the heart must work harder (00:13:26). Complications like preeclampsia or peripartum cardiomyopathy not only endanger mothers now but signal dramatically increased risk of future heart disease and stroke (00:16:25, 00:16:35). Even lesser-known risks, such as SCAD (spontaneous coronary artery dissection), can trigger heart attacks in young, healthy women during or after pregnancy (00:21:25, 00:23:28).
Perimenopause and Beyond: Silent Shifts
As estrogen protection wanes during perimenopause, bad cholesterol rises, blood pressure climbs, and fat redistributes all before most women even have their “final period” (00:33:07, 00:34:00). Hot flashes and night sweats, once dismissed as mere discomforts, are now understood to signal vascular instability and heightened cardiovascular risk (00:35:37). Palpitations are also not to be ignored, as they may conceal dangerous arrhythmias (00:37:03).
What Can Women Do?
The episode closes with practical, empowering guidance. Track menstrual patterns, discuss reproductive history with doctors, know your numbers (blood pressure, cholesterol), and advocate fiercely for appropriate evaluations at every life stage (00:50:22). When symptoms arise, unusual fatigue, shortness of breath, jaw or back pain insist on thorough cardiac screening.
Dr. Arasi Maran leaves us with hope: science is catching up, wearable tech is offering new frontiers, and women are demanding better care (00:59:13). The key message? Your cardiovascular story does not start at old age. From your first period to your last, your heart deserves attention, understanding, and proactive care.
