Stable Angina Pectoris

Stable Angina Pectoris: Insights from Recent Research

Introduction to Stable Angina Pectoris

Stable angina pectoris is a chronic condition characterized by predictable chest pain or discomfort due to myocardial ischemia, typically triggered by physical exertion or emotional stress. It significantly impacts patients' quality of life and can be indicative of underlying coronary artery disease (CAD).

Acupuncture as a Treatment for Stable Angina Pectoris

Recent meta-analyses have explored the efficacy of acupuncture in managing stable angina pectoris. Acupuncture, both alone and in combination with conventional medicine, has been shown to improve anginal symptoms and electrocardiographic (ECG) results. Specifically, patients receiving acupuncture plus medicine exhibited a lower intake rate of nitroglycerin compared to those on medication alone, although no significant difference was observed between the acupuncture-only and medicine groups . These findings suggest that acupuncture can be a beneficial adjunctive therapy for stable angina pectoris.

Ranolazine for Stable Angina Pectoris

Ranolazine, a second-line anti-anginal medication, has been evaluated for its effectiveness in treating stable angina. While ranolazine as an add-on therapy reduced the frequency of angina episodes, it also increased the risk of non-serious adverse events. The evidence regarding its impact on cardiovascular and all-cause mortality, quality of life, and incidence of non-fatal acute myocardial infarction (AMI) remains uncertain and of low quality. Therefore, while ranolazine may offer some symptomatic relief, its overall clinical benefits require further investigation.

Risks Associated with Non-Obstructive CAD in Stable Angina

Patients with stable angina and no obstructive coronary artery disease (CAD) are not necessarily at low risk for adverse cardiovascular events. Studies have shown that these patients have an elevated risk of major adverse cardiovascular events (MACE) and all-cause mortality compared to a reference population without ischemic heart disease. This risk increases with the degree of CAD, highlighting the need for careful monitoring and management of these patients.

Medical Management and Gender Disparities

The medical management of stable angina often includes lifestyle changes, anti-anginal medications, aspirin, and statins. However, there is a notable gender disparity in clinical trials, with significantly fewer women included in studies. This lack of gender-specific data limits the ability to make evidence-based treatment recommendations for women with stable angina. Future research should aim to address this gap to ensure that treatment guidelines are inclusive and effective for all patients.

Alternative Therapies: 1-Deoxynojirimycin (DNJ)

1-Deoxynojirimycin (DNJ), derived from mulberry leaves, has shown promise in improving stable angina symptoms in patients with coronary heart disease (CHD) by enhancing antioxidant and anti-inflammatory capacities. DNJ treatment was associated with improved left ventricular function, reduced inflammatory markers, and increased antioxidant levels, leading to better overall outcomes for patients. This suggests that DNJ could be a valuable addition to the therapeutic arsenal for stable angina pectoris.

Conclusion

Stable angina pectoris remains a significant clinical challenge, with various treatment options available to manage symptoms and improve patient outcomes. Acupuncture and DNJ offer promising adjunctive therapies, while the role of ranolazine requires further clarification. Additionally, the increased risks associated with non-obstructive CAD and the gender disparities in clinical research highlight the need for comprehensive and inclusive treatment strategies. Continued research and tailored approaches are essential to optimize care for all patients with stable angina pectoris.
