Immediate and one-year outcome of patients presenting with Acute Coronary Syndrome complicated by stroke: Findings from the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2)
BMC Cardiovascular Disorders, 08/17/2012
Al Suwaidi J et al. – There is low incidence of in–hospital stroke in Middle–Eastern patients presenting with Acute Coronary Syndrome (ACS) but with very high in–hospital and one–year mortality rates. Stroke patients were less likely to be appropriately treated with evidence–based therapy. Future work should be focused on reducing the risk and improving the outcome of this devastating complication.Methods
- For a period of 9 months in 2008 to 2009, 7,930 consecutive ACS patients were enrolled from 65 hospitals in 6 Middle East countries.
- The prevalence of in–hospital stroke following ACS was 0.70%.
- Most cases were ST segment elevation MI–related (STEMI) and ischemic stroke in nature.
- Patients with in–hospital stroke were 5 years older than patients without stroke and were more likely to have hypertension (66% vs. 47.6%, P = 0.001).
- There were no differences between the two groups in regards to gender, other cardiovascular risk factors, or prior cardiovascular disease.
- Patients with stroke were more likely to present with atypical symptoms, advanced Killip class and less likely to be treated with evidence–based therapies.
- Independent predictors of stroke were hypertension, advanced killip class, ACS type ––STEMI and cardiogenic shock.
- Stroke was associated with increased risk of in–hospital (39.3% vs. 4.3%) and one–year mortality (52% vs. 12.3%).
