Q. A 58-year-old man presents at your primary care clinic with a chief complaint of chest heaviness and a burning sensation localized to the central chest area since this morning. He explains that he has been experiencing this discomfort for a month and has observed a change in the pattern, as it initially appeared during physical exertion but is now happening even at rest, with no radiation to other regions. His medical history includes hypertension, hyperlipidemia, and gastroesophageal reflux disease (GERD). His last follow-up visit to the clinic was 3 months ago. He adheres to his current medications including a beta-blocker, ACE inhibitor, statin, and pantoprazole. His temperature is 98.6°F (37°C), pulse is 90 beats per minute, blood pressure is 140/90 mmHg and respiratory rate is 14 per minute. Physical examination is unremarkable. What is the next appropriate step in this patient’s management?
