RESUMO
OBJECTIVES: We investigated the clinical, electrocardiographic, and echocardiographic determinants of the cardiac status in nonagenarian patients. METHODS: We consecutively examined 654 Caucasian patients (232 males and 422 females) aged ≥90 years. All patients underwent clinical examination, ECG, and transthoracic echocardiography. RESULTS: Their average age was 92.5 ± 2.5 years. Patients were predominately female of older age (p < 0.0001 and p = 0.02, respectively). A history of cardiovascular disease was present in 78.4% of the participants. One third of the patients was hospitalized for cardiovascular causes, with females being twice as many (p < 0.0001). Females showed higher levels of serum cholesterol, triglycerides, and glycemia (p < 0.0001, p< 0.0001, and p = 0.04 respectively). Sinus rhythm was detected in 65%, and atrial fibrillation in 31% of the overall population. Heart rate, PR and corrected QT (QTc) intervals, right bundle branch block (RBBB) and RBBB associated with left anterior fascicular block (LAFB) were higher in males (p < 0.0001, p = 0.036, p = 0.009, p = 0.001, and p = 0.004, respectively). Aortic root dimension, left ventricular (LV) mass index, and indexed LV systolic-diastolic volumes were higher in males (p < 0.001, p < 0.0001, p < 0.001, and p < 0.0001, respectively). Women showed fewer LV segmental kinetic disorders (p = 0009) and higher LV ejection fraction (LVEF; p< 0.0001). Hyperuricemia was positively associated with a history of cardiovascular disease (r = 0.15), glycemia (r = 19), creatininemia (r = 0.50), uremia (r = 0.51), triglycerides (r = 0.19), PR interval (r = 0.14), and left bundle branch block (r = 0.11), and inversely associated with sinus rhythm (r = -0.14) and LVEF (r = -0.17). Diabetes was positively correlated with PR and QTc intervals (r = 0.14 and r = 0.10, respectively), and RBBB with LFAB (r = 0.10), and inversely correlated with LVEF (r = -0.10). CONCLUSIONS: We found a remarkable presence of cardiovascular risk factors, ECG, and structural alterations in hospitalized nonagenarians, which presents more commonly in males.

Objectives The purpose of this study was to investigate whether there are differences among clinical conditions and traditional atherosclerotic risk factors between patients with large abdominal aortic aneurysm and those with occlusive non-coronary arterial disease. Methods We clinically examined 519 patients with asymptomatic abdominal aortic aneurysm and 672 with severe obstructive arterial diseases before surgical repair. Results In patients with abdominal aortic aneurysm, we identified a clear predominance of males ( p < 0.001), more alcohol consumers ( p < 0.05), higher values of diastolic blood pressure ( p < 0.05), higher values of serum creatinine ( p < 0.005), more hyperuricemic patients ( p < 0.005) and less diabetics ( p < 0.001). In patients with occlusive atherosclerotic vasculopathies, we observed more smokers ( p < 0.05), higher systolic blood pressure and more hypertensives ( p < 0.05 respectively) and a prevalence of hypertriglyceridemia ( p < 0.05). Conclusions Patients with abdominal aortic aneurysm were mostly males with diastolic hypertension, impaired renal function and less diabetics, while patients with occlusive arteriopathy were more smokers, hypertensives and more hypertriglyceridemics.

BACKGROUND: Preoperative cardiac assessment may essentially contribute to estimate the operative risk in vascular surgery.This study was undertaken to depict the clinical conditions and cardiac status in patients before elective major vascular surgery. PATIENTS AND METHODS: 143 patients with asymptomatic critical aortic abdominal aneurysm, 119 with high-grade carotid stenosis, and 138 with advanced symptomatic ischemia due to peripheral artery disease were assigned to surgical revascularization. Preoperatively, all subjects completed detailed medical history, physical and laboratory examinations, electrocardiogram, and transthoracic echocardiography. RESULTS: In patients with peripheral artery disease we identified more smokers (p < 0.05), diabetes (p < 0.01), hypertriglyceridemia (p < 0.05), previous myocardial infarction (p < 0.01); the asymptomatic aortic abdominal aneurysm group had a higher body mass index (p < 0.05), diastolic hypertension (p < 0.05), and most had left ventricular anterior hemiblocks (p < 0.001). Patients with critical carotid stenosis were older (p < 0.01), with greater systolic hypertension (p < 0.01), and with a less compromised left ventricular systolic function. CONCLUSIONS: Patients with peripheral artery disease were mostly affected by severe metabolic diseases and by worst cardiac conditions; patients with asymptomatic abdominal aortic aneurysms were of robust physique, and often had left ventricular anterior hemiblocks. Patients with critical carotid stenosis were older and had less cardiomyopathies.

Background: We aimed to depict the electrocardiographic and echocardiographic aspects in patients before elective major vascular surgery.Methods: We evaluated through standard 12 lead electrocardiography and transthoracic echocardiography 469 patients with asymptomatic large abdominal aortic aneurysm (AAA), 334 with critical carotid stenosis (CAS), and 238 with advanced peripheral artery disease (PAD) before surgical revascularization.Results: Patients with AAA were predominantly males (p < .001) with normal sinus rhythm (p = .026), were more affected by atrioventricular block (p = .033) and left anterior fascicular block (p < .001). They also presented larger aortic root size (p < .001) and septal hypertrophy (p = .036), in addition, atrial fibrillation was less frequent in the same group (p = .023). Patients with CAS were of older age (p < .001) with a substantial number of females (p < .001). They presented less left ventricular segmental kinetic disorders and fewer dilated ventricles (p = .004 and p < .001 respectively). Finally, those with PAD had reduced septal and posterior wall thickness (p < .01, p = .009 respectively), greater mitral and aortic annular calcification (p < .001), and were more affected by previous myocardial infarction (p < .001). The PR interval, left anterior fascicular block and aortic root size were independently associated with aneurysm, previous myocardial infarction with PAD, while smaller left ventricular end systolic volumes with carotid artery stenosis.Conclusions: Patients with AAA were mostly affected by cardiac conduction disorders, septal hypertrophy, aortic root dilation and less affected by atrial fibrillation. Patients with CAS were older with more normal sized ventricles, whereas, previous myocardial infarction was most common amongst patients with peripheral artery disease.

BACKGROUND: Whether the use of stentless aortic bioprostheses improves hemodynamics more than stented bioprostheses in the small aortic root is still a matter of debate. METHODS: Early- and mid-term effects were compared between 2 different types of stentless bioprotheses and 1 type of stented bioprosthesis for left ventricular remodelling. The effects of the bioprotheses were studied by echocardiography in 68 patients (age, 74 +/- 7 years) with aortic annulus diameter < or =23 mm who were undergoing prosthesis implantation due to aortic isolated stenosis. Stented bioprostheses (Carpentier-Edwards Perimount [CEP]) were implanted in 36 subjects and stentless bioprostheses (18 Toronto SPV and 14 Shelhigh Super Stentless) were implanted in 32 subjects. RESULTS: A progressive and similar decrease in left ventricular mass of 30% was observed in both stented and stentless bioprostheses at 12 months. A progressive increase in transprosthetic effective orifice area and a decrease in transprothetic pressure gradient were observed at 3, 6, and 12 months in the Toronto group, but these variables showed improvement only at 3 months in the CEP and Shelhigh groups. No mortality occurred during surgery or during the 1-year follow-up period. CONCLUSIONS: Our results confirmed good feasibility of aortic stented and stentless bioprostheses implantation in the elderly population. A 30% decrease in left ventricular mass occurred in the early- and mid-term (12 months) periods after surgery with all 3 types of bioprostheses. Advantages consisting of a progressive increase in transprosthetic effective orifice area and a decrease of the transprosthetic pressure gradient were observed in the Toronto group in comparison to the CEP and Shelhigh groups. These observations may help surgeons in choosing bioprostheses.

BACKGROUND: Because patients with dilated cardiomyopathy tend to have a poor prognosis with medical therapy, surgery with coronary bypass alone or associated with mitral valve repair should be a promising feasible therapeutic option. We evaluated the early effects of surgical coronary revascularization with or without mitral valve repair in patients with severe dilated ischemic cardiomyopathy. METHODS: The study group consisted of 38 patients aged 65 +/- 8 years with severe dilated ischemic cardiomyopathy, chest pain, and heart failure. Twenty-four patients were in a New York Heart Association (NYHA) class > or =3, and 14 patients were in class 2. Twenty patients had a degree of mitral regurgitation defined as an effective regurgitant orifice > or =20 mm2. The mean values (+/-SD) of the EuroSCORE, which evaluates operative risk, were 5 +/- 2.2. Clinical and echocardiographic reevaluation followed at 6 months. RESULTS: All patients underwent coronary artery bypass surgery with a mean of 2.3 +/- 0.8 grafts, and mitral valve repair with annuloplasty and Cosgrove ring insertion were performed in 20 patients. No deaths occurred during the operative period. Ten patients could not be reevaluated at 6 months, and 3 patients died (7.9% mortality). At 6 months, the end-systolic volumes in 15 patients who underwent coronary bypass plus mitral valve repair (group A) and in 13 patients who underwent coronary bypass alone (group B) decreased, respectively, from 139 +/- 56 mL to 121 +/- 94 mL and from 122 +/- 48 mL to 96 +/- 36 mL (P < .05). The wall motion score index also decreased from 1.9 +/- 0.3 to 1.4 +/- 0.4 and from 2.1 +/- 0.3 to 1.8 +/- 0.2, respectively. The mean values of the ejection fraction, the peak early mitral inflow velocity, and the ratio of the peak early mitral inflow velocity to the peak late mitral inflow velocity increased significantly in both groups (P < .001, P < .01, and P < .05, respectively). The mean NYHA functional class significantly improved in both groups (P < .0001). CONCLUSIONS: In patients with severe ischemic dilated cardiomyopathy, surgical coronary revascularization can be safely carried out during the operative and early postoperative periods with low mortality rates. This procedure decreased left ventricular end-systolic volume, consistently increased contractility, and subsequently ameliorated the ejection fraction to produce improvements in clinical condition according to the NYHA functional class. Similar results have been obtained in patients who have undergone coronary bypass surgery and mitral valve repair, despite a higher operative risk and longer cardiopulmonary bypass circulation and aortic cross-clamping times.

We report an exceptional case of ischemic heart disease due to the origin of the left coronary circumflex artery from the pulmonary artery in a 50-year-old woman. She had undergone surgery for aortic coarctation when she was 16 years old. This abnormality was associated with other congenital defects such as tunnel subaortic stenosis, small aortic valve annulus, numerous left ventricular false tendons, and aortic bicuspid valve. Cardiac surgery verified the origin of the left circumflex from the pulmonary artery. The left internal mammary artery was positioned on the obtuse marginal coronary branch. Her clinical state was moderately improved 3 months after surgery.

BACKGROUND: The links between pulmonary venous flow (PVF) and left atrial stasis have not been adequately defined in nonvalvular atrial fibrillation. In this setting, we aimed to study the relationship between PVF and the occurrence of left atrial spontaneous echocontrast (SEC) in order to evaluate its clinical relevance in the assessment of the cardioembolic risk. METHODS: We studied by echocardiography 109 patients with nonvalvular atrial fibrillation (65 males, 44 females, mean age 66 +/- 9 years). The left ventricular end-diastolic and end-systolic diameters, the left ventricular fractional shortening, the left ventricular mass, and the left atrial volume were measured by transthoracic approach. The systolic and diastolic peak velocities of PVF, their ratio (pS/pD) and the velocity-time integrals were assessed by means of transesophageal investigation; furthermore, the presence of left atrial SEC or thrombi was recorded. Among clinical data, thromboembolic events occurring within 15 days before the echocardiographic study, history of hypertension and duration of atrial fibrillation were also collected. RESULTS: Left atrial SEC showed a significant correlation with left atrial volume (p < 0.001), detection of thrombi (p < 0.001), thromboembolic events (p = 0.002) and pS/pD ratio (p < 0.001). By multivariate analysis, pS/pD ratio was independently correlated with left atrial volume, age and left ventricular fractional shortening (r2 = 0.29, p < 0.001). The sensitivity and specificity of pS/pD ratio to predict the presence of severe SEC was 73.9 and 62.5%, respectively. CONCLUSIONS: In patients with nonvalvular atrial fibrillation, pS/pD ratio is significantly related to the occurrence of left atrial SEC and seems to be a useful parameter concurring to assess left atrial stasis and thromboembolic risk.

We report an uncommon case of an insulin-treated diabetic patient, presenting severe hypoglycemia, coma, marked sinus bradycardia and QT prolongation. Intravenous administration of glucose and atropine awaked the patient and increased heart rate but did not affect QT prolongation. Basal and exercise electrocardiogram excluded primary diseases associated with QT prolongation. Pathophysiologic aspects of electrocardiographic and clinical findings occurring in the hypoglycemic patients are briefly discussed.
