Background: Careful management of lipid abnormalities in patients with coronary heart disease (CHD) or an acute coronary syndrome (ACS) can reduce the risk of recurrent cardiovascular events. The extent of hyperlipidemia in these very high-risk patients in the United Arab Emirates (UAE), along with the treatment strategies employed, is not clear.

Methods: The Dyslipidemia International Study II was a multinational observational analysis carried out from 2012 to 2014. Patients were enrolled if they had either stable CHD or an ACS. Patient characteristics, lipid levels, and use of lipid-lowering therapy (LLT) were recorded at enrollment. For the ACS patients, the LLT used during the 4 months' follow-up period was documented, as were any cardiovascular events.

Results: A total of 416 patients were recruited from two centers in the UAE, 216 with stable CHD and 200 hospitalized with an ACS. Comorbidities and cardiovascular risk factors were extremely common. A low-density lipoprotein cholesterol level of <70 mg/dl, recommended for patients at very high cardiovascular risk, was attained by 39.3% of the LLT-treated CHD patients and 33.3% of the LLT-treated ACS patients at enrollment. The mean atorvastatin-equivalent daily statin dose was 29 ± 15 mg for the CHD patients, with 13.7% additionally using ezetimibe. For the ACS patients, the daily dosage was 23 ± 13 mg at admission, rising to 39 ± 12 mg by the end of the 4-month follow-up. The use of nonstatin agents was extremely low in this group.

Conclusions: Despite LLT being widely used, hyperlipidemia was found to be prevalent in ACS and CHD patients in the UAE. Treatment strategies need to be significantly improved to reduce the rate of cardiovascular events in these very high-risk patients.
