Why are women more likely to suffer from microvascular angina? Uncover the mysterious factors behind it!
Microvascular Angina (MVA) is a special type of angina that occurs under the normal coronary arteries of the heart, but patients often experience chest pain caused by insufficient blood flow. The condition is more common in women, and the reasons behind it have sparked widespread interest among scientists.
Microvascular angina is a painful heart-related condition that puts patients at increased risk of heart attacks and other heart problems.
Characteristics of microvascular angina
Patients with microvascular angina often experience a feeling of heaviness, tightness, or pressure in the chest, which may be accompanied by symptoms such as sweating, nausea, shortness of breath, and fatigue. Although the cause of this type of chest pain is not clearly defined, it is generally accepted by the medical community that it may be caused by abnormal microvascular function. Narrowing of these small blood vessels can deprive certain areas of the heart of oxygen, causing severe chest pain.
Special risks for women
Data show that women are more likely to suffer from microvascular angina than men, and the reasons behind this are still not fully understood. Some experts believe that fluctuations in female hormones and different metabolic mechanisms within the body may be to blame. In addition, in the pursuit of a healthy lifestyle, many women often delay diagnosis due to the inconvenience of cardiovascular examinations.
Some studies have found that patients with microvascular angina often also have other vascular diseases, such as migraines and Raynaud's phenomenon, which may further exacerbate the risk of heart disease.
The pathophysiology of microvascular dysfunction
The usual physiological manifestations of microvascular angina are structural and functional changes in cardiac microcirculation. Such changes may include endothelial dysfunction, vascular remodeling, and increased microvascular resistance. When small blood vessels constrict or fail to adapt to changes in pressure, the heart muscle may become hypoxic, and case studies show that many patients show systemic dysfunction at the microvascular level, resulting in insufficient blood flow to the heart muscle.
Clinical Diagnosis and Testing
The diagnosis of microvascular angina mainly relies on the elimination method. Doctors need to confirm the condition through clinical assessment, stress testing, coronary angiography and other examinations. An exercise stress test is the first step in finding out whether your heart is getting enough blood flow during exercise. In addition, with further imaging techniques such as cardiac MRI, many doctors are able to obtain more detailed diagnostic results.
Treatment Plan and Management
Currently, there are many treatments for microvascular angina, and common ones include the use of calcium channel blockers, beta-blockers and other drugs. However, beta-blockers can sometimes worsen coronary artery spasm, making treatment more challenging. Non-drug treatment cannot be ignored. Many patients improve their condition through healthy diet and moderate exercise. In addition, mind-body therapies such as cognitive behavioral therapy and mindfulness meditation can also effectively help patients relieve pain.
Thinking about the future
The long-term effects of microvascular angina significantly increase the risk of heart attacks and other cardiac events. Therefore, regular check-ups and early diagnosis are crucial. However, women are more likely to encounter diagnostic and treatment challenges due to gender-specific risks and symptoms. Therefore, integrating medical resources so that women can more conveniently obtain professional cardiac medical services is the direction that medicine needs to work towards in the future. Faced with this challenge, what changes can social support and improvements in the medical system bring about?
