Background. Diabetes mellitus and new left bundle branch block (LBBB) increase the risk of adverse cardiac outcomes and are considered a coronary artery disease equivalent. Objective. The aim of our study was to determine whether the presence of new or presumably new left bundle branch block could be the first manifestation of coronary artery disease in diabetic patients. Design. We performed a crosssectional analysis which included 273 patients with new LBBB admitted between January 2011 and June 2013 in the Cardiovascular Diseases Institute Iasi. The median follow-up was 7 days (hospitalization period). Patients were divided into two groups according to their glycemic status: diabetic and non-diabetic patients. Results. Our study demonstrates that the presence of new LBBB in diabetic patients is unequivocally associated and could be the first manifestation of an extensive coronary artery disease. Diabetic patients had either one, two or three coronary artery diseases (48.09%) and were more likely to have a decreased ejection fraction (EF) < 50% (p <0.001), almost half of them having an EF <30 %. Conclusions. The association of diabetes mellitus with new LBBB is a high probability criterion for the diagnosis of coronary artery disease, even in asymptomatic patients.

Background. Aortic dissection is a life-threatening disorder and up to 20% of patients die before receiving medical care. Marfan syndrome is noted in 5–9% of individuals who suffer from aortic dissection. Case presentation. We present the case of a 53 years old woman, with undiagnosed Marfan syndrome, addressed to our clinic complaining about thoracolumbar pain appeared 4 days ago, after a trauma. According to the revised Ghent criteria for the diagnostic of Marfan syndrome she had a positive family history and more than 7 points of systemic findings. She was also diagnosed with extensive aortic dissection and right pneumothorax. Because of the cachexia and important scoliosis, the operative and post operative risk was high and we decided a medical management. She remained haemodynamically stable, with a false lumen partially trombosed, and was discharged home after 23 days. Discussion. The particularity of our case represent the diagnostic of Marfan syndrome after the appearance of a vital risk vascular complication – aortic dissection, the emergency surgical intervention being limited by the clinical and prognostical particularities of these two comorbidities. Conclusion. Aortic dissection in Marfan syndrome represents a diagnostic and therapeutic challenge for interdisciplinary practitioner physicians.
