Impact of Life's Simple 7 on the incidence of major cardiovascular events in high-risk Spanish adults in the PREDIMED study cohort

[EN] Introduction and objectives The Life's Simple 7 strategy of the American Heart Association proposes 7 metrics of ideal cardiovascular health: body mass index (BMI) < 25 mg/m2, not smoking, healthy diet, moderate physical activity ≥ 150 min/wk, total blood cholesterol < 200 mg/dL, systolic and diastolic blood pressures < 120 and < 80 mmHg, respectively, and fasting blood glucose < 100 mg/dL. It is important to assess the combined effect of these 7 metrics in the Spanish population. We prospectively analyzed the impact of baseline Life's Simple 7 metrics on the incidence of major cardiovascular events in the PREDIMED cohort (57.5% women, average baseline age, 67 years). Methods The healthy diet metric was defined as attaining ≥ 9 points on a validated 14-item Mediterranean diet adherence screener. An incident major cardiovascular event was defined as a composite of myocardial infarction, stroke, or cardiovascular death. Cox regression was used to calculate multivariable adjusted hazard ratios (HR) and their 95% confidence intervals (95%CI) for successive categories of health metrics. Results After a median follow-up of 4.8 years in 7447 participants, there were 288 major cardiovascular events. After adjustment for age, sex, center, and intervention group, HRs (95%CI) were 0.73 (0.54-0.99), 0.57 (0.41-0.78), and 0.34 (0.21-0.53) for participants with 2, 3, and ≥ 4 metrics, respectively, compared with participants with only 0 to 1 metrics. Conclusions In an elderly Spanish population at high cardiovascular risk, better adherence to Life's Simple 7 metrics was progressively associated with a substantially lower rate of major cardiovascular events.
[ES] Introducción y objetivos La estrategia Life's Simple 7 de la American Heart Association propuso 7 métricas de salud cardiovascular ideal: índice de masa corporal (IMC) < 25, no fumar, dieta saludable, actividad física moderada ≥ 150 min a la semana, colesterol total < 200 mg/dl, presión arterial sistólica < 120 mmHg y diastólica < 80 mmHg y glucemia basal < 100 mg/dl. Resulta de gran interés valorar el efecto combinado de estas 7 metas. Se analizó prospectivamente el impacto de las métricas basales Life's Simple 7 en la incidencia de eventos cardiovasculares mayores en la cohorte PREDIMED (el 57,5% mujeres; media de edad inicial, 67 años). Métodos La métrica de dieta saludable se definió como alcanzar al menos 9 puntos en una escala validada de 14 puntos de adhesión a dieta mediterránea. Se definió evento cardiovascular mayor incidente como infarto de miocardio, ictus o muerte de causa cardiovascular. Se usó regresión de Cox para estimar hazard ratios (HR) ajustadas multivariables con intervalos de confianza del 95% (IC95%) para categorías sucesivas de métricas de salud cardiovascular. Resultados Tras seguir a 7.447 participantes durante una mediana de 4,8 años, se registraron 288 eventos. Respecto a los participantes con solo 0-1 métricas, tras ajustar por edad, sexo, centro y grupo de intervención, se observaron HR (IC95%) 0,73 (0,54-0,99), 0,57 (0,41-0,78) y 0,34 (0,21-0,53), para 2, 3 y 4 o más métricas respectivamente. Conclusiones En una población española con alto riesgo cardiovascular, la presencia de un mayor número de métricas se asoció progresivamente con una reducción sustancial en la tasa de eventos cardiovasculares mayores.
