Tako-Tsubo syndrome, spontaneous coronary dissection and microvascular disease: Sex-differences

Area of Science:

• Cardiology
• Endocrinology
• Women's Health

Background:

• Coronary angiography reveals no epicardial disease in up to 50% of patients, predominantly women.
• Common conditions include Takotsubo cardiomyopathy, coronary microvascular dysfunction, and spontaneous coronary artery dissection.
• These syndromes involve complex neurohormonal interactions.

Purpose of the Study:

• To review the role of estrogen state changes in cardiovascular conditions affecting women.
• To elucidate the mechanisms linking estrogen to vasomotor tone and endothelial dysfunction.
• To describe sex-dependent differences in prevalence, pathogenesis, and prognosis.

Main Methods:

• Literature review focusing on estrogen's impact on coronary physiology.
• Analysis of mechanisms underlying Takotsubo cardiomyopathy, coronary microvascular dysfunction, and SCAD.
• Examination of sex-based differences in cardiovascular disease.

Main Results:

• Estrogen state fluctuations can alter vasomotor tone and endothelial function.
• These changes contribute to coronary epicardial and microvascular spasm.
• Estrogen influences coronary arterial wall stability, impacting disease development.

Conclusions:

• Estrogen plays a significant role in the pathogenesis of these conditions in women.
• Understanding estrogen's influence is crucial for diagnosing and treating these syndromes.
• Sex-specific approaches are necessary for managing cardiovascular health in affected women.
