Correlation between Carotid Atherosclerosis and Left Ventricular Dysfunction at Echocardiography

Ana Gabriella Gonçalves Amorim et al. Ana Cristina Camarozano Wermelinger

Abstract

Introduction

Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Primary prevention, through early diagnosis, is necessary to enable proper treatment and control disease progression, reducing mortality and public health expenditures.

Objective

Correlate carotid artery atherosclerosis (evaluated by Doppler echocardiography) and left ventricular dysfunction (evaluated by echocardiography) and to correlate the findings with the patients’ cardiovascular risk.

Method

A total of 286 medical records of patients who underwent carotid Doppler echocardiography and transthoracic echocardiography were analyzed. The data analyzed were: presence of atherosclerotic plaque and degree of stenosis, left ventricular ejection fraction and presence of diffuse or segmental left ventricular contractile disorders.

Results

Of the 238 reports of carotid Doppler echocardiography, 18 had stenosis greater than 70% in the carotid artery and 14 of those had left ventricular contractile disorders (p = 0.045). Of the patients with very high cardiovascular risk, 61 had carotid artery stenosis (p < 0.001); 51 patients with very high cardiovascular risk had contractile disorders (p < 0.001). Of the 266 echocardiography reports, 37 had reduced left ventricular ejection fraction. Of these, 25 had very high cardiovascular risk (p < 0.001).

Conclusion

There was a positive relationship between carotid artery stenosis, reduced left ventricular ejection fraction and left ventricular (diffuse or segmental) contractile disorder with very high cardiovascular risk. It was also possible to correlate carotid stenosis with contractile disorder, although this study did not demonstrate any correlation between carotid stenosis and reduced left ventricular ejection fraction.

BACKGROUND: Approximately 30% of perioperative CVA of myocardial revascularization surgery (MRS) are a result of carotid injuries, without reduction of risk confirmed by perioperative intervention. OBJECTIVES: Evaluate the impact of carotid disease and perioperative intervention in patients subjected to MRS. METHODS: Observational, retrospective study, evaluating 1169 patients aged > 69 years undergoing MRS from January, 2006 and December, 2010, monitored, on average, for 49 months. All patients were subjected to ultrasonography of carotids before MRS. It was defined as carotid disease when lesion > 50%. The primary outcome was composed of CVA incidence, transitory ischemic accident (TIA) and death due CVA. RESULTS: Prevalence of carotid disease was of 19.9% of patients. The incidence of primary outcome between unhealthy and healthy patients was of 6.5% and 3.7%, respectively (p = 0.0018). In the first 30 days, there were 18.2% of events. Were related to carotid disease: renal dysfunction (OR 2.03, IC95% 1.34-3.07; p < 0.01), peripheral arterial disease (OR 1.80, IC95% 1.22-2.65; p < 0.01) and previous myocardial infarction (OR 0.47, IC95% 0.35-0.65; p < 0.01). Regarding the primary outcome, were associated the previous TIA (OR 5.66, IC95% 1.67-6.35; p < 0.01) and renal dysfunction (OR 3.28, IC95% 1.67-6.45; p 70%, perioperative carotid intervention demonstrated an incidence of 16% in primary outcome compared to 4.3% in conservatory treatment (p = 0.056) with no difference between percutaneous and surgical approaches (p = 0.516). CONCLUSION: Carotid disease increases the risk of CVA, TIA or death due to CVA in MRS. However, the carotid intervention was not related to reduction of primary outcome.

Prevalence of carotid stenosis in patients referred to myocardial revascularization surgery

Marcelo Pereira da Rosa et al. Vera Lúcia Portal

BACKGROUND: Although the carotid stenosis is the main cause of cerebrovascular accident, the prevalence of clinically significant stenosis (>50%) remains unknown in our country, mainly in individuals with a surgical indication for elective myocardial revascularization surgery. OBJECTIVE: To identify the prevalence and degree of carotid stenosis in individuals with a surgical indication for MRS in a reference center in Cardiology in Brazil. METHODS: Transversal study of 457 consecutive patients of both genders, evaluated between May 2007 and April 2008 through ultrasonography with color Doppler of the carotid arteries, during the preoperative period of elective MRS. The statistical analysis was performed with the SPSS program, version 10.1. A p value <0.05 was considered significant. Seven patients were lost throughout the study. RESULTS: The mean age (±standard deviation) was 62.2 ± 9.4 years and 65.6% of the patients were males. The prevalence of significant carotid stenosis was 18.7%. As for the stratification of the degree of carotid stenosis: absence of stenosis was observed in 3.6%; stenosis < 50% was observed in 77.8%; stenosis between 50% and 69% was observed in 11.6%; stenosis between 70% and 99% was observed in 6.9% and arterial occlusion was observed in 0.2% of the individuals. The sensitivity and specificity regarding the carotid bruit were 34.5% and 88.8%, respectively. CONCLUSION: The prevalence of significant carotid stenosis was high in the studied sample, which suggests this is a high-risk population for the occurrence of cerebrovascular accident.
