Abstract
BACKGROUND Takotsubo syndrome is a stress cardiomyopathy, characterized by reversible left ventricle (LV) apical ballooning in the absence of significant angiographic coronary artery stenosis. The frequent association with emotional stress suggests in this disease an autonomic nervous system involvement. We could think that a therapeutic treatment targeting heart sympathetic dysfunction could be of crucial importance. METHODS From January 2010 to June 2012, 886 patients were consecutively evaluated at Cardarelli Hospital, Naples, Italy. Among these, 48 patients met takotsubo cardiomyopathy (TCM) criteria. Each patient was assessed with history and physical examination, 12-lead electrocardiogram, serum troponin, coronary arteriography, and left ventricular angiogram, perfusion myocardial scintigraphy with technetium 99m, with echocardiography and 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy. At discharge, the surviving patients were randomly assigned to α-lipoic acid (ALA) treatment (600mg once daily) or placebo. Following discharge, after the initial TCM event, patients returned to our outpatient clinic at Internal Medicine of the Second University Naples for the follow-up evaluation quarterly until 12 months. Routine analysis, myocardial damage serum markers, oxidative stress serum markers, pro-inflammatory cytokines, and sympathetic tone activity were evaluated in all patients. RESULTS ALA administration improved MIBG defect size at 12 months compared to placebo. CONCLUSIONS Adrenergic cardiac innervation dysfunction in TCM patients persists after previous experience of transient stress-induced cardiac dysfunction. ALA treatment improves the adrenergic cardiac innervation. This study evaluates whether sympatho-vagal alterations are TCM event-related.

Abstract
OBJECTIVE We examined the effects of peri-procedural intensive glycemic control (IGC) during early percutaneous coronary intervention (PCI) on restenosis rate in hyperglycemic patients with ST-segment elevation myocardial infarction (STEMI). RESEARCH DESIGN AND METHODS A total of 165 hyperglycemic patients (glucose ≥ 140 mg/dl) with first STEMI undergoing PCI were studied. Patients were randomized to IGC for almost 24 h after PCI (n = 82; glucose, 80-140 mg/dl) followed by multidose sc insulin during the hospital stay or conventional glycemic control (CGC; n = 83; glucose, 180-200 mg/dl) followed by conventional therapy. Coronary angiography was performed at study entry and at 6-month follow-up. Blood samples for glycemia, hemoglobin A1c, inflammatory markers (C-reactive protein and TNF-α), monocyte chemoattractant-protein-1, and oxidative stress (nitrotyrosine) were collected immediately before and 24 h, 30 and 180 d after PCI. RESULTS After insulin infusion, mean plasma glucose during the peri-procedural period was greater in the CGC group than in the IGC group (CGC, 191 ± 15 mg/dl; IGC, 145 ± 35 mg/dl; P < 0.001). After the insulin infusion period, the levels of markers of oxidative stress (nitrotyrosine), inflammation (C-reactive protein, TNF-α), and monocyte chemoattractant-protein-1 were significantly higher in CGC patients compared with IGC patients. Moreover, ICG during PCI reduces restenosis by half (48 and 24%) at 6 months. During follow-up, there was no difference in mortality rates, glucose, inflammatory and oxidative stress markers among the groups. In-stent restenosis was positively associated with mean plasma glucose levels as well as oxidative stress and inflammatory markers during the insulin infusion period. CONCLUSIONS In hyperglycemic patients with STEMI, optimal peri-procedural glycemic control by reducing oxidative stress and inflammation may improve the outcome after PCI.

Abstract
Indications to surgery for adeno-tonsillar inflammatory disorders and analysis of the effectiveness of surgical treatment, compared with watchful waiting strategy, continue to be the subject of scientific debate. The present investigation focuses on the surgical activity of 14 Italian Otorhinolaryngological Units between 1999 and 2004. Surgical interventions (adeno-tonsillectomy, adenoidectomy, tonsillectomy) on 26915 children (age range: 2-11 years) were considered. Data on adeno-tonsillar interventions were analysed in relation to other interventions of ENT interest, performed in the same units and in the same period. Adeno-tonsillar interventions accounted for 35.4% of all operations of ENT interest. Adeno-tonsillectomy accounted for 56.6% of overall adeno-tonsillar operations, adenoidectomy 31.6%, tonsillectomy 11.8%. The percentage for the three interventions was homogeneous in the period of the study and in the recruited units. The percentage of children who underwent adeno-tonsillar surgery in paediatric units was higher as compared to general units, as far as concerns the overall number of operations performed. In southern Italy, the number of adeno-tonsillar interventions, in general, and of adeno-tonsillectomy, in particular, was higher compared to that in northern Italy. Results of the present study suggest that environmental factors, cultural issues and local health demands, may influence indications and, therefore, the different incidence of the operations under consideration in the units taking part in the investigation.

Abstract
BACKGROUND The proinflammatory cytokines have been implicated in the pathogenesis of heart failure. Recent studies have shown that beta-adrenergic blockade can modulate cytokine production. This study investigates the different impact of different degrees of sympathetic antagonism on circulating levels of cytokines in patients with heart failure resulting from ischemic dilated cardiomyopathy (IDC). METHODS AND RESULTS Thirty-five patients with IDC were randomly assigned to receive metoprolol or carvedilol in an open-label study. Echocardiographic measurements and circulating levels of tumor necrosis (TNF)-alpha and interleukin (IL)-1beta and IL-6 were obtained at baseline and after 3 months of treatment. The 2 beta-blockers significantly improved the left ventricular ejection fraction and reduced end-diastolic and end-systolic volume. The magnitude of these changes was greater with carvedilol than with metoprolol (respectively P < .001, P < .05, and P < .05). Both treatments induced a significant decrease in the levels of cytokines (for all P < .01), but the decrease in TNF-alpha and IL-1beta was more consistent in the carvedilol group ( P < .01). CONCLUSION Our results support the hypothesis that a more complete block of sympathetic activity by carvedilol induces a greater decrease in the circulating levels of proinflammatory cytokines that could explain, at least in part, the better improvement in the left ventricular remodelling and systolic function in patients with IDC.

Abstract
Exercise training elicits an improvement in work capacity and in left-ventricular function in patients with coronary artery disease. An improvement in myocardial oxygen supply accounts for these effects. The aim of this study was to test the hypothesis that exercise training could favorably influence diastolic perfusion time, a major determinant of subendocardial perfusion. Twenty-two male patients with coronary artery disease were randomized to a training or control group. At the study entry and after one year, all patients underwent an exercise stress test. After one year, rest heart rate was lower and diastolic perfusion time was higher in the training group but not in the control group. At peak of exercise, diastolic perfusion time increased and ST-segment depression decreased significantly in the training group but not in the control group. A significant relation was found between the R-R interval and the diastolic perfusion time either before or after training, with a difference in the intercepts of two regressions. Training shifted updown-line regression, effecting a higher value of diastolic perfusion time for a given value of heart rate. Thus, training increases diastolic perfusion time, independently from the effect on heart rate. This mechanism may contribute to the improvement of myocardial perfusion.

Abstract
In patients (pt) with coronary artery disease diastolic duration is an important determinant of myocardial oxygen supply. To assess the effects of physical training on diastolic duration, twelve male pt with previous infarction were studied. During 12 month training program the physical exercise was of progressively increasing intensity, duration and frequency. Training induced a significant reduction in heart rate. Both systolic and diastolic blood pressure were unchanged. The mean values of electromechanical systole were lower after training. On the contrary, the training induced a lengthening of diastolic duration expressed as percentage of cardiac cycle (% diastole) from 51.4 +/- 2.6 to 57.5 +/- 3.8% (p < 0.001). Thus, this results validate the hypothesis that physical exercise training can improve myocardial perfusion through an increase in diastolic duration, partially independent of bradycardia.

Abstract
Since an abnormal shortening of diastolic duration during exercise in the patients with coronary artery disease was demonstrated, time course of diastolic period (cardiac cycle minus electromechanical systole) calculated from polycardiographic recording has been assessed in patients with X syndrome and in normal age-matched subjects during supine ergometer exercise. All patients with X syndrome had positive exercise stress response (more than 0.1 mV of ST segment depression). Duration of diastole expressed as percent of cardiac cycle was significantly shorter at the intermediate steps and at the peak of exercise in patients with X syndrome compared with normal subjects (p less than 0.05). When the relationship between heart rate and diastolic time was examined, an inverse nonlinear regression was found both in normal subjects and in patients with X syndrome. The exercise values of diastolic time observed in patients with X syndrome were significantly shorter than those predicted as normal diastolic time heart rate relation. Thus the patients with X syndrome demonstrated abnormalities in the decrement of diastolic time with exercise. We hypothesized that this disproportionate shortening, by reducing subendocardial blood flow, might induce a worsening of ischemic response to exercise.

Abstract
The present study has been performed to assess the effects of alinidine on diastolic duration during exercise in chronic coronary artery disease. Twelve male patients with stable effort angina and without previous myocardial infarction were studied. They received alinidine or placebo in a double-blind randomized crossover trial for 3 days after a wash-out period of 4 days. Alinidine was administered at a dosage of 30 mg 3 times a day. At the end of each treatment the patients underwent upright bicycle exercise. Left ventricular time intervals were obtained by means of carotid thermistor plethysmography. Diastolic duration was calculated by subtracting the electromechanical systole from the R-R interval and expressed as a percentage of the cardiac cycle (%D). Alinidine increased both total exercise duration from 246.7 +/- 120.7 to 346.6 +/- 114.1 s (p less than 0.05) and time to 0.1-mV ST segment depression from 98.3 +/- 53 to 187.2 +/- 105 s (p less than 0.05). Similarly the drug induced a reduction of the rate-pressure product and of the extent of ischemic ST segment depression during exercise. %D was increased by alinidine both at rest and during exercise. A direct linear regression between R-R and %D was found after both alinidine and placebo treatments either at rest or during exercise. Nevertheless, no difference was observed between both slopes and intercepts. Therefore, since the relationship between R-R interval and %D was unaffected by alinidine, it was possible to hypothesize that the changes in diastolic duration were due only to the bradycardic action of the drug.

Abstract
To evaluate the effects of diltiazem (240 mg/day) on the left ventricular function, we studied 13 patients with coronary artery disease (CAD). Comparison with placebo was made in a double-blind randomized crossover study. Both placebo and diltiazem were administered for 5 weeks. We assumed left ventricular systolic time intervals assessed by polycardiography as parameter of ventricular function. Diltiazem induced a significant decrease in pre-ejection period (p less than 0.01) as well as pre-ejection period/left ventricular ejection time ratio (p less than 0.01). Thus, our results suggest that diltiazem improves the contractile state of ischemic myocardium in CAD patients.

Abstract
The present work was performed in order to assess the differences in electrocardiographic and hemodynamic responses to supine and upright dynamic exercise of patients with coronary artery disease. Changes in heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure, rate-pressure product (RPP) and ST segment depression during supine and upright bicycle stress test were compared in twenty patients suffering from stable effort angina and without previous myocardial infarction. In the supine posture lower values of HR were observed at rest, during stress test and during three minutes of the recovery period. Conversely, in all patients both SBP and DBP were higher during the stress test in the supine position decubitus. No significant changes in RPP was observed between the two different postures. Finally, ST segment didn't show differences at rest between the upright and supine position. All the patients had a lower ischemic threshold during exercise in the supine position than in the upright one. In fact an ST segment depression greater than 1 mm was observed during stress test in the supine position at lower work-load levels and at lesser HR values. Consequently for given HR, SBP and DBP ST segment, depression was greater in the supine rather than in the upright position.

Abstract
Early diastolic time intervals have been assessed by means of the echopolycardiographic method in 17 pregnant women who developed hypertension during pregnancy (HP) and in 14 normal pregnant women (N). Systolic time intervals (STI), stroke volume (SV), ejection fraction (EF), and mean velocity of myocardial fiber shortening (VCF) were also evaluated. Recordings were performed in the left lateral decubitus (LLD) and then in the supine decubitus (SD). In LLD, isovolumic relaxation period (IRP) was prolonged in the hypertensive pregnant women compared with normal pregnant women (HP 51 +/- 12.5 ms, N 32.4 +/- 15 ms p less than 0.05), whereas time of the mitral valve maximum opening (DE) was not different in the groups. There was no difference in SV, EF, and mean VCF, whereas STI showed only a significant (p less than 0.05) lengthening of pre-ejection period (PEP) in HP. When the subjects shifted from the left lateral to the supine decubitus position, left ventricular ejection time index (LVETi) and SV decreased significantly (p less than 0.05) in both normotensive hypertensive pregnant women. IRP and PEP lengthened significantly (p less than 0.05) only in normals, whereas they were unchanged in HP. DE time did not vary in either group. In conclusion, hypertension superimposed on pregnancy induces lengthening of IRP, as well as of PEP, and minimizes the effects of the postural changes in preload on the above-mentioned time intervals.
