Key result
Therapy with ASA and beta-blocker in a 6-day-old newborn with suspected microvascular angina resulted in good clinical condition and no further ischemic episodes at 5 months follow-up.
Case Report (n=1)
This case report describes a rare instance of suspected microvascular angina in a newborn successfully managed with aspirin and a beta-blocker.
May support ASA and beta-blocker trial in rare neonatal microvascular angina; hypothesis-generating and requires prospective validation.
Myocardial ischemia in pediatric population is uncommon and usually due to congenital heart disease or extracardiac conditions leading to poor coronary perfusion. A 6-day-old newborn presented with respiratory distress and signs of heart failure. ECG, echocardiography, and laboratory results were consistent with myocardial ischemia. Coronary angiography was performed to exclude anomalous origin of coronary arteries, showing normal coronary artery origin and course. Thrombophilia and extra-cardiac causes were ruled out. Clinical conditions improved with mechanical ventilation and diuretics, enzyme levels lowered, repolarisation and systolic function abnormalities regressed, but ischemic electrocardiographic and echocardiographic signs still presented during intense crying. Becaues of suspicion of microvascular angina, therapy with ASA and beta-blocker was started. At 5 month followup, the baby was in good clinical condition and no more episodes were recorded. We believe it is an interesting case, as no similar cases have been recorded till now.

Cataldo et al. (2012) conducted a case report in Suspected microvascular angina (n=1). ASA and beta-blocker was evaluated on Clinical condition and ischemic episodes. Therapy with ASA and beta-blocker in a 6-day-old newborn with suspected microvascular angina resulted in good clinical condition and no further ischemic episodes at 5 months follow-up.
