I met this 68-year-old male. This letter is in reference to Mr. John Smith, a 68-year-old male, referred to our cardiology clinic due to recent onset of exertional chest pain. He resides at 15 Oak Avenue, London, W1 1AA. Mr. Smith has noticed central chest tightness occurring with moderate exertion, such as walking up a flight of stairs or brisk walking for more than 10 minutes. The symptoms began approximately three months ago and are typically relieved by rest within 5 minutes. He has not noticed radiation of pain to his arm or jaw, nor any associated shortness of breath, palpitations, or dizziness. His significant past medical conditions include hypertension diagnosed in April 2020, for which he takes Ramipril and Amlodipine, and stable angina diagnosed in January 2022, managed with Isosorbide Mononitrate. He also has Type 2 Diabetes Mellitus, diagnosed 5 years ago, and hyperlipidaemia. Mr. Smith is a former smoker, having quit 10 years ago after smoking 20 cigarettes per day for 30 years. He consumes alcohol occasionally, approximately 4 units per week. He is retired and lives with his wife. His father died at 72 years of age from a myocardial infarction, and his mother has hypertension. There is no other significant non-first-degree family history of cardiovascular disease. On physical examination, Mr. Smith was afebrile with a blood pressure of 145/88 mmHg, heart rate 72 bpm, respiratory rate 16 breaths per minute, and oxygen saturation 98% on room air. Weight was 95 kg, which, with height 175 cm, gives BMI 31 kg/sqm. Cardiovascular examination revealed a regular pulse, normal heart sounds with no murmurs. Lung fields were clear to auscultation. Abdominal examination was unremarkable. Peripheral pulses were palpable and symmetrical. Resting ECG shows sinus rhythm at 72 bpm, with a normal QRS axis and duration. ST segment and T wave morphology are normal and the corrected QT interval is 420 ms. An echocardiogram performed in October 2024 showed a left ventricular ejection fraction of 55% with mild mitral regurgitation and normal left ventricular dimensions. There was no evidence of significant valvular heart disease or wall motion abnormalities. A chest X-ray performed in September 2024 showed clear lung fields and normal cardiac silhouette. Blood test results from October 2024 showed HbA1c 7.1%, which is elevated compared to 6.8% six months prior. Renal function and electrolytes were within normal limits. A lipid profile on 1 November 2024 showed non-HDL and LDL cholesterol levels of 3.8 mmol/L and 2.5 mmol/L respectively. This shows an improvement from his prior non-HDL cholesterol of 4.2 mmol/L six months ago. The primary differential diagnosis is worsening stable angina due to progression of coronary artery disease, given the new onset of exertional chest pain despite existing anti-anginal therapy and his significant cardiovascular risk factors including hypertension, hyperlipidaemia, and diabetes. The plan involves optimising his current medical therapy, considering a stress test to evaluate for inducible ischaemia, and referral to a dietician for aggressive lifestyle modifications. We will initially increase his isosorbide mononitrate to twice daily dosing and consider adding a beta-blocker if symptoms persist. Another differential diagnosis is atypical chest pain, potentially musculoskeletal in origin, though less likely given the exertional nature and prompt relief with rest. However, this will be reassessed if cardiac investigations prove negative. The plan for this involves symptomatic management with analgesia and physical therapy if required, after excluding a cardiac cause. We anticipate that with optimising his medical therapy and adherence to lifestyle changes, Mr. Smith's symptoms will improve and his cardiovascular risk will be better managed. Potential challenges include adherence to dietary changes and regular exercise, which we will address through counselling and support from the dietician. I plan to review Mr. Smith in three months to assess his symptomatic response to treatment and review investigation results. I have advised the patient to continue with his prescribed medications and to attend all scheduled appointments. He has been advised to seek immediate medical attention if he experiences chest pain that is more severe, prolonged, or associated with new symptoms such as shortness of breath or dizziness. I have advised the patient to live life completely normally.
