Abstract
Background Effective treatment of non-ST-segment elevation acute coronary syndromes (NSTEACS) requires careful assessment of both ischaemic and bleeding risks. We aimed to analyse risk distribution and evaluate antiplatelet prescription behaviours in real-life settings. Methods Data from 1100 NSTEACS patients in Buenos Aires, Argentina, from the Buenos Aires I Registry, with a 15-month follow-up, were analysed. In-hospital and 6-month GRACE scores, CRUSADE, and Precise DAPT scores were calculated. Results The mean age was 65.4 ± 11.5 years with a majority being male (77.2%). In-hospital mortality was 2.7%, primarily due to cardiovascular causes (1.8%). Bleeding events occurred in 20.9% of patients, with 4.9% classified as ≥ BARC 3. Predominance of low bleeding (71.3%) and ischaemic (55.8%) risks on admission was observed. At 6 months, the low-risk Precise category (70.9%) and GRACE (44.1%) categories prevailed. Linear correlation analysis showed a moderately positive correlation (r = 0.61, p < .05) between ischaemic–haemorrhagic risks. Regarding the prescription of antiplatelet agents, in the low ischaemic–haemorrhagic risk group, there was a predominance of aspirin + clopidogrel (41.2%) over other high-potency antiplatelet regimens (aspirin + ticagrelor or prasugrel). In the low ischaemic and high haemorrhagic risk group, aspirin and clopidogrel were also predominant (58%). Conclusions Our analysis underscores the significant relationship between ischaemic and haemorrhagic risks during NSTEACS hospitalisation. Despite the majority of patients falling into the low-intermediate risk category, the prescription of P2Y12 inhibitors in real-life settings does not consistently align with these risks.
