Impact of frailty and functional status on outcomes in elderly patients with ST-segment elevation myocardial infarction undergoing primary angioplasty: rationale and design of the IFFANIAM study.

The IFFANIAM study (Impact of frailty and functional status in elderly patients with ST segment elevation myocardial infarction undergoing primary angioplasty) is an observational multicenter registry to assess the impact of frailty and functional status on outcomes of elderly patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary angioplasty. STEMI patients age 75 years or older undergoing primary angioplasty will be extensively studied during admission in 4 tertiary care Hospitals in Spain, assessing their baseline functional status (Barthel index, Lawton-Brody index), frailty (Fried criteria, FRAIL scale [fatigue, resistance, ambulation, illnesses, and loss of weight]), comorbidities (Charlson index), nutritional status (Mini Nutritional Assessment-Short Form), and quality of life (Seattle Angina Questionnaire). Participants will be managed according current recommendations. The primary outcome will be the description of 1-year mortality, its causes, and associated factors. Secondary outcomes will be functional capacity and quality of life. Results will help to better understand the impact of frailty and functional ability on outcomes in elderly STEMI patients undergoing primary angioplasty, thus potentially contributing to improving their clinical management. Higher life expectancy has resulted in a large segment of elderly population and an increase in myocardial infarction in these patients. This calls attention to healthcare systems to focus on promoting methods to improve the clinical management of this population.
