Background
In women with evidence of ischemia and no obstructive coronary artery disease the underlying mechanism is most often attributed to coronary microvascular dysfunction. Higher rates of adverse cardiovascular events, specifically heart failure with preserved ejection fraction, are present in women with coronary microvascular dysfunction, leading to the hypothesis that coronary microvascular dysfunction may contribute to the progression of heart failure with preserved ejection fraction.
Case summary
A 55-year-old, Caucasian woman with a past medical history of chest pain and shortness of breath was referred to our tertiary care center and diagnosed as having coronary microvascular dysfunction by invasive coronary reactivity testing. After 10 years of follow-up care for coronary microvascular dysfunction, she presented to an emergency room in acute heart failure and was diagnosed as having heart failure with preserved ejection fraction.
Discussion
The current case report provides a specific example in support of existing studies that demonstrate that coronary microvascular dysfunction may be a precursor of heart failure with preserved ejection fraction. Further research is needed to establish causality and management.
