Background: Acute aortic dissection (AAD) is a life-threatening cardiovascular condition with high morbidity and mortality.
We sought to assess clinical profiles as well as outcomes of AAD in a predominantly Hispanic population and to explore the relationship between this condition and uncontrolled/untreated hypertension in this community.
Material and Methods: This was a single-center, retrospective, cross-sectional study of patients admitted with AAD over a 10 years period.
Results: Fifty-nine cases of AAD were included in the analysis. The group of Hispanics with AAD had more females (48.3%, p=0.002), more dyslipidemia and coronary artery disease (p=0.006 and 0.05, respectively), and a tendency to be older and have more hypertension and diabetes compared to non-Hispanics. Although 70.2% of all patients had hypertension, only 52.5% of them were being treated; of those, only 66.7% achieved optimal blood pressure control prior to presentation. Only 47.4% received beta-blockers for blood pressure control in the acute setting. Longer length of in-hospital stay was associated with older age, higher troponin and creatine kinase levels, and presence of hypertension. In-hospital death occurred in 10 (17%) patients and mortality was significantly associated with higher serum creatinine (p=0.01).
Conclusions: Hispanic patients with AAD were more likely to be female, of older age, and have more cardiovascular risk factors in comparison to non-Hispanics. In addition, significant under-treatment of hypertension in this population and underutilization of beta-blockers for blood pressure control in the acute settings was evident. Better prevention and timely treatment may improve outcomes for this condition in this population.
