Introduction
Advanced age is an important risk factor for patients with acute coronary syndromes(1). As population aged, centenarians or oldest old patients in the other term, became quite common in daily routine practice. Because of widely available modern catheter laboratory facilities, improved device technology and increased experience in interventional cardiology, primary percutaneous coronary intervention become the therapy of choice in very elderly with ST-segment elevation myocardial infarction(2). Despite of reported complications, both radial and femoral approach can be performed successfully in these ages. On the other hand, regardless of all improvements for this safe and proven treatment option, patient’s invasive procedure related fear, and their relative’s opinion in these settings are the major barrier for timely performed percutaneous coronary interventions(1,3).
Case report
A 98-year-old female was referred to our emergency room within 30 minutes of continuous chest pain and rapidly progressive dyspnea. Sinus bradycardia (39 bpm) and hypotension (85/55 mmHg) were noted at admission. Her electrocardiogram’s showed signs of acute inferior and right ventricular myocardial infarction (Figure 1A-B). No pulmonary crackles and other physical examination abnormalities were observed. Echocardiography showed mild right ventricular dilatation, inferior wall akinesia, moderate mitral insufficiency, and 45% left ventricular ejection fraction (LVEF). Immediately after 300 mg acetylsalicylic acid, 600 mg clopidogrel and 5000 IU unfractionated heparin load, a transvenous pacemaker was implanted and a coronary angiography was performed (Figure 2). At the same session, a drug eluting stent was implanted for proximal right coronary artery occlusion, and medical management decision made for borderline contra-lateral coronary lesions (Figure 2). She was complication free in-hospital course. The pacemaker removed on the second day and she discharged on the sixth day of hospital admission. In two-year follow-up at her 100 years of age; the patient was event-free, physically and mentally well with 54% LVEF, a mild mitral regurgitation, and slight increase in kidney function tests. Her medical treatment was optimized and invited for regular clinical visits.
Discussion
People at their nineties (nonagenarians) are rapid growing proportions of patients treated with primary percutaneous coronary interventions in current clinical practice. Also, age-related physiological changes, disease progression, and frailty increase both potential benefits of mechanical revascularization and procedure-related adverse outcomes (e.g. access site bleeding and thrombotic complications). We would like to stress it out that, timely invasive treatment in very elderly is better in acute setting in terms of short- and long-term outcomes. Including more patiaents at these ages to future randomized trials will help to improve our clinical experience in acute setting, broad current knowledge on this population, and might address advanced age-related problems in follow-up care. In this case report, we summarized our daily practice as performing coronary intervention in urgent settings in patients >90 years old along with mid to long term follow-up is safe but rare in the current literature.
