Whatever the mechanism, young patients with prehypertension have impaired aortic elasticity compared with healthy controls. This finding has suggested that the development of overt hypertension may be prevented or delayed by using the agents that have the ability to reduce arterial stiffness by regressing and/or preventing functional and structural changes on the arterial wall.
A huge subaortic left ventricular aneursym was diagnosed in an asymptomatic 22-year-old male patient. The walls of aneurysm were calcific and compressed the left atrium. Also, a saccular descending aortic aneursym and moderate mitral insufficiency associated with subaortic left ventricular aneurysm were found in the current case. Up to now, the coexistence of congenital left ventricular aneurysm and saccular aortic aneursym has not been reported in the literature. We present the first case of congenital left ventricular aneurysm combined with saccular aortic aneurysm in descending thoracic aorta in this case report.
Careful electrocardiographic and echocardiographic evaluation of patients with TIA may help assess the outcome of patients and guide therapeutic interventions.
Hypertrophic obstructive cardiomyopathy (HOCM), the cause of which is unknown, is a heart disease characterized by obstruction of the left ventricular outflow tract and an increase in interventricular septum thickness. Octreotide, a synthetic analogue of somatostatin, was administered subcutaneously to 15 patients for 6 months in order to determine its efficacy in HOCM. Echocardiographic examination was performed in each patient before we had initiated treatment and after treatment. Interventricular septum thickness, interventricular septum thickness/left ventricular posterior wall thickness, and subaortic gradient decreased significantly at the end of treatment. The ratio of the mitral valve E to A waves increased significantly. We observed that octreotide treatment caused a significant decrease in interventricular septum thickness and subaortic pressure gradient. Before and after therapy left ventricular enddiastolic diameter, left ventricular endsystolic diameter, ejection fraction and fractional shortening were not changed. No adverse effect was observed during the therapy. According to our results, octreotide has some beneficial effects on HOCM and it seems to be a new therapeutic approach for HOCM.
Several studies have proven that noninvasive reperfusion criteria (NRC) have prognostic significance in patients receiving thrombolytic therapy (TT) after acute myocardial infarction (acute MI). In this study, we investigated the relationship between NRC and pulsed tissue Doppler (PTD) parameters in patients receiving TT after acute MI, and the role of PTD in the management and follow-up of patients with acute MI. The study group(n= 41)was divided into four subgroups defined as: anterior and posterior MI, with or without NRC. In the first PTD measurements (2-3 days after acute MI), all acute MI patients had significantly smaller peak systolic (S-wave) velocity in all evaluated segments and longer Q-Speak durations (time elapsed from the inscription of the Q-wave on the surface ECG to the peak of the S-wave in PTD) as compared with control patients(n= 22; P < 0.001 for both). Among the diastolic parameters, the E/A ratio was significantly smaller in the study group compared with the control group(P < 0.001). Among the patients who had received TT in the first 2 hours, those patients who had NRC displayed significantly higher peak S-wave values in all evaluated segments than those without NRC(P < 0.05). The second PTD study (4-5 weeks after acute MI), revealed that the difference between the systolic PTD parameters of the noninfarcted regions of the study and control groups disappeared. Infarct-related segments, however, displayed significant improvement only in patients having NRC. There was a significant positive correlation between the mean mitral annular S-wave velocity and left ventricular ejection fraction(r = 0.59, P < 0.001). In conclusion, a significant relationship was observed between the PTD parameters and the NRC, which are known to have prognostic significance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
