The inflammatory abdominal aortic aneurysm and coronary artery disease. Case report and review.

Inflammatory abdominal aortic aneurysm (IAAA) is defined as an unusually thickened aneurysmatic wall, encircled by a wide dense perianeurysmal and/or retroperitoneal fibrosis with adjacent tissues adhesion, and is now considered as an extreme shape of the common phlogistic process involved in atherosclerotic plaque formation. Latest studies demonstrated that inflammation plays an important role in coronary disease and in other atherosclerosis manifestations. We introduce the clinical case of a patient with IAAA who developed an acute myocardial infarction 6 months after the surgical procedure on the aorta. Through a literature review about IAAA we stress the clinical usefulness of the inflammatory markers as independent predictors in management of patients with coronary disease and we present the hypothesis, related to the introduced case, of an advanced coronary disease, aggravated or clinically revealed after the cytokine storm related to important localized inflammatory engagements or great vascular surgery treatments.

The usefulness of clinical indexes in the evaluation of cardiovascular risk in non cardiac surgery.

AIM: The preoperative cardiac evaluation of a patient who undergoes noncardiac surgery is a very important problem, particularly for diagnostic tools used. Aim of this study is to test the usefulness of 4 most used clinical indexes for the evaluation of cardiovascular risk in the management of patients who undergo noncardiac surgery. METHODS: The study is based on a retrospective analysis of a group of 45 patients, who underwent extracardiac surgery in biennium 2002-2004. The cardiovascular risk scores of Goldman, Detsky, Lee and Eagle were used; a comparison among the different scores was done. RESULTS: Six out of our 45 patients had perioperative cardiovascular complications, and 4 of them died. The Eagle and Lee scores were more predictive than Goldman and Detsky ones. About the 13 echocardiographic tests recorded, no one of them modified the patient preoperative risk. CONCLUSIONS: In the preoperative assessment of risk, the Eagle score was more useful than the others ones and improved the negative predictive value of the Goldman and Detsky scores. The preventive application of the clinical indexes allows optimizing the preoperative stratification of the risk, limiting the request of useless examinations and offering to the patient a well appropriated preoperative management, reducing the incidence of complications.

[Double-chamber right ventricle: a case report].

The double-chamber right ventricle is a congenital cardiac malformation usually associated with other cardiac defects, seldom isolated and in adult subject. It is characterized by the presence of an anomalous bundle that divides the right ventricle into two chambers. The clinical and electrocardiographic signs of isolated double-chamber right ventricle are few and not specific. An echocardiographic diagnosis of isolated double-chamber right ventricle is reported. In a 18-year-old asymptomatic male with systolic murmur 2/6 at third space over the left sternal border, right ventricular hypertrophy and intraventricular conduction delay at ECG, two-dimensional echo showed an anomalous transversal muscle bundle that divided the right ventricle into two chambers, superior and inferior. Color Doppler showed a diastolic tricuspidal-like flow through a paraseptal discontinuity of the bundle and a systolic jet that reached the right atrium, with a pressure gradient of 30.9 mmHg. The absence of symptoms and other cardiopathy, without significant right outflow tract obstruction, was considered as an index of a good prognosis; therefore cardiac catheterization was not advised.

[Cross-over study on the effects of ketanserin vs enalapril in the treatment of hypertension].

The aim of the study was to compare antihypertensive efficacy and safety of ketanserin with those of enalapril in the treatment of hypertension. The study design was controlled, cross-over, with randomized sequences. The efficacy was evaluated from data of 19 (9 males, 10 females) mean age 59.5 +/- 10.1 years, weight kg 68 +/- 12.1 with hypertension lasting over 5 years. Posology was ketanserin 20-40 mg bid, and enalapril 10-20 mg bid; both for three weeks. The efficacy was good with both treatments and the effects similar. In fact, at the end of the treatment with ketanserin, supine SBP was decreased 10 +/- 20 and DBP 5 +/- 10 mmHg, standing SBP was reduced 15 +/- 19 and DBP 7 +/- 15 mmHg. With enalapril supine SBP decreased 25 +/- 16 and DBP 10 +/- 13 mmHg, standing SBP was reduced 16 +/- 19 and DBP 8 +/- 18 mmHg. Changes of heart rate by either treatment were of no clinical importance. The safety of treatment with ketanserin was excellent, while 14.3% of the patients treated with enalapril had undesirable effects.

[Diastolic flow in the left ventricle of healthy subjects: a study using processing of intracardiac color-Doppler maps].

UNLABELLED: Aim of the study was to evaluate the left ventricular (LV) diastolic flow propagation. Ten healthy subjects (28 +/- 6 years) were examined. Two-dimensional echocardiography and color-Doppler at mitral valve were performed. A cine-loop was transferred on-line to a color image processor. Selected digitized images were stored on microdisk. LV end-diastolic, end-systolic and early filling (EF) volumes were measured. Doppler measurements across the mitral valve were obtained: peak E, peak A, E/A, the integral (VTI) of E and A, acceleration and filling time. Extension of color and time base to apex, time of EF and atrial filling (AF) were obtained by M-color, along the base-apex axis. On frames of EF and AF of 2D-color, diastolic maps were processed: surface area and pixel velocity, mean (mv) and peak (pv), were obtained of the entire color area and of 4 selected areas, 2 mm wide: 1 along the annulus-apex axis (LAx), and 3 transverse, planes, at the annulus, at papillary (1/3) and at the apex (2/3 of LAx). Three-dimensional plot and velocity distribution were obtained. Values of pixel of the entire color area were stored on microdisk and processed using a Macintosh PC. For each transverse section, 1 pixel wide, mv and pv were obtained, and data were referred to normalized axis and the mean was calculated. RESULTS: end-diastolic volume index (EDVI): 66 +/- 7, end-systolic volume index (ESVI): 26 +/- 5 ml.(ABSTRACT TRUNCATED AT 250 WORDS)

[Pathophysiologic classification of heart failure: contribution of echocardiography].

Aim of the study was to examine the role of echocardiography to classify patients with heart failure. Fifty-seven subjects (32 dilated cardiomyopathy (DCM), 9 aortic regurgitation (AR), 16 hypertensives (HT)--4 in Class (CI) NYHA I, 24 II, 15 III, 14 IV--were studied by M-2D echo. Eighty-seven normals (N) were the control group; 11 were controlled after clinical improvement (3.4 +/- 3.8 months); 11 after worsening (12 +/- 17). We have evaluated: left ventricular diastolic dimension (LVIDd), wall thickness/radius ratio (H/R), diastolic (D) and systolic volume (S Vol), ejection fraction (EF), systolic arterial pressure/end-systolic volume ratio (P/V), and stress. LVIDd and stress were increased in all groups; H/R reduced, except in HT and in Cl I; EF and P/V reduced except in Cl I. Between I and II LVIDd was different; between II and III all parameters were different, between III and IV only EF and P/V. According to regression S-D Vol, EF-P/V and EF-stress we identify the reduction of EF and the related mechanisms, ie reduced contractility or increased afterload. Thus, according to P/V and stress, we classify the patients in 4 pathopysiologic classes: 1 and 2 with P/V within 2 SD N: 1 with stress within 2SD N, EF and H/R normal; 2 with stress greater than +2SD, H/R normal and EF reduced; 3 and 4 with P/C less than -2 SD N: 3 with normal, 4 with stress greater than +2 SD. In the 1 and 2, 1 out 14 is in III Cl NYHA, none in IV; in 3,6 out 8 are in II, in 4, 9 out 35 are in Cl less than III. In the follow-up, in 8 of the improved patients, EF and P/V were increased and stress reduced; in 3, EF was reduced. In 8 of the worsened, EF and P/V were reduced, LVIDd and stress increased; in 3 EF and LVIDd were increased, P/V reduced. This study demonstrates discordance between Cl NYHA and echo, and how classification of NYHA does not give information about the several components of heart failure. However LVID and EF are not sufficient. By a correlation of echo-parameters of contractility, afterload and pump performance, we may suggest a classification of heart failure in pathophysiologic classes.
