Brief Summary: Background Influenza vaccination is recommended in patients pts with cardiovascular disease however there is a shortage of clinical studies proving its protective effect on clinical course of coronary artery disease CAD The aim of the study was to evaluate the effect of influenza vaccination on the incidence of coronary events in pts with CAD confirmed by coronary angiography
Detailed Description: A possible relation between influenza and higher mortality from cardiovascular problems was first noticed in early nineteen hundreds after epidemics in Europe and United States were discovered 1 In the last decade many studies implicating an important role of inflammation and infection Herpes virus Chlamydia pneumoniae Helicobacter pylori in development and progression of atherosclerosis 23 and markers of inflammation like hs-CRP fibrinogen have become new independent cardiovascular risk factors 4

Many general physicians now recommend influenza vaccination in patients with coronary artery disease CAD despite shortage of studies proving its protective effect on clinical course of CAD In literature we found only a few reports exploring the hypothesis that influenza vaccination might reduce the incidence of myocardial infarction MI and acute coronary syndromes ACS

Naghavi et all in retrospective case- control study of 218 patients with chronic coronary disease reported that influenza vaccination was strongly associated with freedom from new MI during the same influenza season OR 033 95 CI 013 to082 p0017 5 Gurfinkiel et all evaluated in prospective single- blind Fluvacs study that preventive impact of vaccination on subsequent ischemic events at 6 months follow-up Study group consisted of 301 patients after coronary angioplasty PCI The first primary outcome- cardiovascular death occurred in 2 in vaccine group compared with 8 in the control group p001 and triple composite end point death myocardial infarction and hospitalization from ischemia occurred in 11 in vaccine group vs 23 in controls p00009 6 In the contrary Jackson et all in largest study of 1378 survivors of first MI in long median 23 year follow-up didnt find the benefit of influenza vaccine on the protection against recurrent coronary events 7

The aim of our study is to evaluate the influence of influenza vaccination on the incidence of cardiac events cardiovascular death myocardial infarction acute coronary syndromes coronary revascularization and hospitalizations from ischemia in patients with angiographically confirmed coronary disease
