New heart procedure offers hope for stubborn chest pain

This study tests a minimally invasive procedure called cardioneuroablation for people with variant angina (chest pain from heart artery spasms) that doesn't improve with medication. The procedure uses a catheter to target nerve clusters on the heart to reduce abnormal signals that may trigger spasms. The study will enroll 16 adults aged 18-80 to see if the procedure safely reduces pain and spasm episodes.
