A infecção por vírus influenza está associada a um risco aumentado de eventos cardiovasculares. A revisão sistemática da Cochrane sobre este tema avaliou o potencial impacto da vacinação na prevenção primária ou secundária de eventos cardiovasculares. A análise agregada de quatro ensaios clínicos controlados e aleatorizados, de moderada qualidade metodológica, com 1 682 doentes, mostrou uma redução de 55% no risco relativo de morte cardiovascular nos doentes com patologia coronária. No entanto, não se verificou a existência de evidência robusta para determinar o impacto da vacina na prevenção primária de eventos cardiovasculares. As orientações nacionais e internacionais para a vacinação contra o vírus Influenza em doentes com patologia coronária, são suportadas pelos dados desta revisão sistemática.
Influenza infections are associated to increased risk of cardiovascular events. The systematic review of Cochrane Collaboration evaluated the role of influenza vaccination on primary or secondary prevention of cardiovascular events. The meta-analysis of four randomized controlled trials with moderate quality, including 1 682 patients with coronary artery disease, showed a 55% risk reduction on cardiovascular mortality. Data evaluating the role of vaccination in primary cardiovascular prevention were not robust. Portuguese and international recommendations for influenza vaccination in patients with coronary artery disease are then supported by this systematic review.
