Abstract

Background: A substantial progress has been made in Poland in the field of acute coronary syndromes (ACS) management over the last 10 years.<br />Aim: To present the data from the Polish Registry of Acute Coronary Syndromes (PL-ACS) collected between 2003 and 2009. Changes in treatment strategies and outcomes in ST-segment myocardial infarction (STEMI) were analysed.<br />Methods: We analysed patients enrolled to the PL-ACS Registry - a nationwide multicenter, prospective observational study of consecutive patients hospitalised with ACS in Poland.<br />Results: Overall, 284,162 patients with ACS were enrolled in 512 centres including 88 invasive cardiology centres. The STEMI was diagnosed in 35-36% of these patients in 2003-2005, and this proportion remained stable at 30% to 32% in 2006-2009. The mean age of STEMI patients increased from 62.5 years in 2003 to 64.5 in 2009. During this period, women represented 32.7% to 34.6% of the STEMI patients. Proportion of patients presenting with pulmonary oedema or cardiogenic shock decreased with time, from 15.5% in 2003 to 8% in 2009. Delays to reperfusion tended to reduce over time: pain-to- -admission time was 240 min in 2005 and 229 min in 2009 and door-to-balloon time was 32 and 25 min in 2005 and 2009, respectively, with the delay being longer in the elderly population. The proportion of patients undergoing coronary angiography showed a constant increase, from 55% in 2003 to 84% in 2009. Percutaneous coronary intervention was performed in 51% and 78% of patients in 2003 and 2009, respectively. At the same time, the proportion of patients undergoing thrombolysis declined from 14% to 1%. Aspirin, beta-blocker, statin and ACE inhibitor use was constantly high, while nitrate use declined from 82% to 15%. The proportion of patients receiving clopidogrel increased from 40% to 97% over the analysed period. Significant reductions in mortality rates were observed: in-hospital mortality decreased from 11.9% to 6.4%; 30-day mortality from 13.5% to 9.6%; and 12-month mortality from 19.8% to 15.4% in 2003 and 2009, respectively. Invasive treatment strategy was associated with better in-hospital and long-term patient survival.<br />Conclusions: The PL-ACS Registry results demonstrate low short- and long-term mortality rates in STEMI patients, mainly due to frequent use of interventional strategy, satisfactory logistics and appropriate drug therapy used. As a consequence, hospitalisation time has shortened. However, there are several issues that need to be improved such as shortening of pre- -hospital delays and increasing the rate of invasive treatment in patients presenting with cardiogenic shock.
