Myocardial infarction (MINOCA) and ischemia (INOCA) with non-obstructive coronary disease are linked to heart failure (HF). Further research is needed for risk factors, diagnosis, and prevention strategies for MINOCA and INOCA related HF.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Heart Failure Research
Background:
- Myocardial infarction (MINOCA) and ischemia (INOCA) with non-obstructive coronary disease are emerging presentations of coronary syndromes.
- These conditions are increasingly recognized due to advancements in cardiovascular imaging.
- Both MINOCA and INOCA are associated with heart failure (HF).
Purpose of the Study:
- To review the relationship between MINOCA, INOCA, and heart failure.
- To highlight the impact of microvascular dysfunction in INOCA and HFpEF.
- To identify gaps in understanding and management of HF in MINOCA and INOCA.
Main Methods:
- Review of recent clinical literature and imaging techniques.
- Analysis of the association between MINOCA/INOCA and heart failure.
- Examination of underlying mechanisms including left ventricular dysfunction and endothelial dysfunction.
Main Results:
- MINOCA is associated with significant adverse outcomes, including prevalent heart failure events.
- INOCA, particularly involving microvascular dysfunction, is linked to heart failure with preserved ejection fraction (HFpEF).
- HF is a common complication in both MINOCA and INOCA.
Conclusions:
- MINOCA and INOCA are significantly related to heart failure, necessitating further investigation.
- Established secondary prevention strategies for HF in MINOCA are lacking.
- Coronary microvascular dysfunction in INOCA contributes to diastolic dysfunction and HFpEF.
