Abstract
Abstract
Background
Percutaneous coronary intervention (PCI) of bifurcation lesions is associated with higher rates of adverse events, and currently it is unclear whether PCI or coronary artery bypass grafting (CABG) is the safer treatment for these patients at very long-term follow up.
Objectives
To investigate the impact of bifurcation lesions on observed all-cause 10-year mortality in the SYNTAX trial.
Methods
In the SYNTAX Extended Survival study, 10-year observed mortality was compared among four groups: (a) presence of ≥1 bifurcation lesion and treatment with PCI (n=649), (b) no bifurcation lesion and treatment with PCI (n=248), (c) presence of ≥1 bifurcation lesion and treatment with CABG (n=651), and (d) no bifurcation lesion and treatment with CABG (n=239).
Results
Compared to patients without bifurcations, those with bifurcation lesion(s) treated with PCI had a significantly higher risk of all-cause death (19.8% vs 30.1%; HR: 1.55, 95% CI: 1.12 to 2.14; p=0.007), whereas following CABG, mortality was similar in patients with or without bifurcation lesion(s) (23.3% vs 23.0%; HR: 0.81, 95% CI: 0.59 to 1.12; p=0.207). (Figure1) There was a significant interaction between bifurcation lesion(s) and treatment arm (p for interaction=0.006).
In PCI patients, at 5-years there was no significant difference in mortality between 1- vs 2-stent techniques, whereas at 10-years, a 2-stent technique was associated with higher mortality (33.3% vs 25.9%; HR: 1.51, 95% CI: 1.06 to 2.14; p=0.021, Figure2).
Conclusions
Bifurcation lesion(s) require special attention from the heart team discussion, considering the higher 10-year all-cause mortality associated with PCI. Careful evaluation of bifurcation lesion complexity may be helpful in decision-making.

Abstract
Abstract
Background
Clinical presentation with STEMI is considered as a highly prothrombotic condition often associated with recurrent ischemic events. The role of aspirin as part of antiplatelet regimens in STEMI patients needs to be clarified especially in the context of new potent P2Y12 inhibitors
Aim
To assess the benefit and risk of 23-month ticagrelor monotherapy after one month of DAPT against the conventional 12-month DAPT with aspirin and ticagrelor followed by aspirin monotherapy among STEMI patients in the GLOBAL LEADERS trial.
Methods
We did a post hoc analysis of STEMI patients in the GLOBAL LEADERS trial (2092 patients). We compared the experimental ticagrelor monotherapy group (1062 patients) with the standard 12-month DAPT group (1030 patients) in rates of GLOBAL LEADERS predefined primary (composite of all-cause mortality or non-fatal, new Q-wave myocardial infarction (MI) and secondary end points (BARC 3 or 5 bleeding). NACE (Net Adverse Clinical Events) and POCE (Patient- Oriented Composite End points). We also compared GLOBAL LEADERS predefined end points in STEMI, UA, NSTEMI and CCS in both treatment arms.
Results
At two years, there were no significant differences in rates of GLOBAL LEADERS primary end points in patients who had or did not have STEMI. BARC bleeding in either treatment group didn't vary significantly among STEMI, NSTEMI and UA. Nevertheless, the experimental strategy had led to significant increase in BARC bleeding in CCS compared with STEMI at 1 and 2 years. There were similar rates of NACE and POCE in both the experimental and reference treatment groups at 1 and 2 years post PCI.
Conclusions and relevance
The incidence of GLOBAL LEADRER defined end points has not been impacted by STEMI presentation. Our findings suggest that an earlier cessation of DAPT at 1 month post primary PCI, with continuation of a potent P2Y12 antagonist monotherapy, could be safe and avoids additional bleeding risk in the STEMI setting. Given the post-hoc nature of the analysis, our findings should not necessitate changes in recommendations for practice by professional associations and regulatory agencies. However, all reported findings should rather be considered only as hypothesis-generating and need be replicated in dedicated large-scale randomized trials to further assess the role of Aspirin free antithrombotic strategies post PCI in STEMI.

Abstract
Aim Covid-19 has had a dramatic impact on the healthcare systems globally. Despite efforts to maintain systems of cardiovascular care during the pandemic, public health responses to the virus have contributed to adverse cardiovascular outcomes. Herein, we summarize current evidence detailing the impact of Covid-19 on interventional cardiology. Methods According to PRISMA criteria, a systematic review was performed through Medline, Embase, and Cochrane databases, to identify reports on the impact of Covid-19 on interventional cardiovascular procedures. We identified 50 published studies that met the prespecified inclusion and exclusion criteria. Results In the acute setting, several datasets report a reduction of acute coronary syndrome (ACS) admission by 40% globally (−40%, 95% CI 37–43 from the National Health Service hospital trusts in England). Most surveys and registries reported a numerically higher impact on NSTEMI/unstable angina cases compared to STEMI (−42%, 95% CI 38–46 and −23%, 95% CI 16–30 respectively, from the National Health Service hospital trusts in England). In STEMI care pathways, several studies report increased delays between symptom onset and first medical contact (105 min, 95% CI 45–222 during the pandemic vs 71 min, 95% CI 30–180 before it, p<0.001, from the National STEMI registry in Spain), with a subsequent increased duration of the ischaemic period (200 min, 95% CI 140–332 during the pandemic vs 233 min, 95% CI 150–375 before it, p<0.001, from the National STEMI registry in Spain). Importantly, hospital “door-to-balloon” times were unchanged. Most studies suggest similar in-hospital mortality for STEMI during the pandemic compared to historic controls (1.7% vs 1.8%, p=0.67 from British National Institute of Cardiovascular Outcomes Research database). An increased incidence of mechanical complications were observed (41.2% vs 19.6%, p=0.030, from an Italian monocentric experience). In the United States (New York city), overall mortality from ischemic heart diseases depicted a 2-fold increase during the pandemic (relative change 2.39, 95% CI 1.39–4.09). Of note, in the same city home deaths increased from 35/day in 2013–2017 to 200/day during the pandemic. These data suggest that ACS incidence has not decreased, but more likely patients presenting ischemic symptoms may have not contacted health care services, and have died at home. Conclusions The Covid-19 pandemic has adversely impacted outcomes in patients with ischemic heart disease (IHD). The diagnosis and treatment of IHD should be designated a health system priority that remains intact during pandemic events as the magnitude of harm induced by its interruption is substantial.

Abstract
Abstract
Background
Diabetes mellitus (DM) is a well-known cardiovascular risk factor present in up to a third of patients undergoing transcatheter aortic valve implantation (TAVI). How DM might influence outcomes after TAVI procedures remains controversial. The aim of this study was to determine differences in outcomes after TAVI according to diabetes status.
Methods
The CENTER (Cerebrovascular EveNts in patients undergoing TranscathetER aortic valve implantation with balloon-expandable valves versus self-expandable valves)-collaboration was a global patient level dataset of patients undergoing transfemoral TAVI from 2007 to 2018. In this analysis, the study examined differences in baseline patient characteristics, 30-day stroke and mortality, and in-hospital outcomes between DM and non-DM patients.
Results
Of the 11,440 patients included, 31% (n=3,550) were diabetic and 69% (n=7,890) were non-diabetic. Diabetics were younger, had a higher body mass index (BMI) and overall a worse cardiovascular risk profile than non-diabetics. There were no differences between DM and non-DM patients regarding in-hospital mortality (4.8% vs 5.3%, RR: 0.9, 95% CI: 0.7–1.1, p=0.46), myocardial infarction (0.9% vs 0.7%, RR: 1.4, 95% CI: 0.9–2.2, p=0.17), stroke (1.7% vs 2.0%, RR: 0.9, 95% CI: 0.6–1.2, p=0.36), major or life threatening bleeding (5.9% vs 6.3%, RR: 0.9, 95% CI: 0.8–1.1, p=0.44) and permanent pacemaker implantation (13.6% vs 13.4%, RR: 1.0, 95% CI: 0.9–1.1, p=0.69). Similarly, 30-day rates of all-cause mortality (5.4% vs 6.1%, RR: 0.9, 95% CI: 0.8–1.1, p=0.30) and stroke (2.0% vs 2.4%, RR: 0.8, 95% CI: 0.6–1.1, p=0.23) did not differ between diabetic and non-diabetic patients. Accordingly, in multivariate analysis, DM was not an independent predictor of mortality.
Conclusions
In this global collaboration, diabetic patients undergoing transcatheter aortic valve replacement had more cardiovascular comorbidities, were younger and had a higher body mass index than non-diabetics. They had similar periprocedural complications, in-hospital and 30-day mortality rates. In multivariate analysis, diabetes was not associated with increased mortality.

Abstract
RESUMO A leishmaniose visceral americana (LVA) é uma zoonose de transmissão vetorial na qual o cão tem papel importante na epidemiologia da doença. No Brasil, a elevada prevalência da infecção em cães está diretamente correlacionada com o aumento no risco de ocorrência de casos de LVA. O objetivo deste estudo foi investigar a fauna flebotomínica e verificar a soroprevalência da leishmaniose visceral canina (LVC) na localidade Pedra 90, no município de Cuiabá. Para o levantamento entomológico, armadilhas CDC foram utilizadas de agosto de 2014 a julho de 2015. Na avaliação sorológica dos cães, o teste imunocromatográfico DPP LVC foi utilizado para a triagem das amostras, enquanto o ensaio imunoenzimático (EIE) para o diagnóstico da LVC (Bio-Manguinhos) foi empregado como teste confirmatório. O trabalho vem acrescentar à fauna flebotomínica do município de Cuiabá as espécies Lu. andersoni, Lu. braziliensis, Lu. bourrouli e Lu. scaffi, não registradas em publicações anteriores. Além disso, entre as espécies de flebotomíneos com importância médica, Lu. cruzi, Lu. flaviscutellata e Lu. whitmani foram capturadas. No inquérito canino, a prevalência de LVC observada na localidade Pedra 90 foi de 1,14%, indicando que a região pode ser considerada como área de transmissão.

Abstract
Utilizou-se a técnica da RT-PCR para a detecção da região 5' UTR do genoma do vírus da diarréia viral bovina (BVDV) em pools de soros sangüíneos provenientes de um rebanho, constituído por 226 animais, que apresentava distúrbios da reprodução. A partir das amostras individuais de soro e de acordo com a categoria dos animais e o número de animais por categoria foram formados 10 pools (A a J) de soros. A primeira avaliação revelou a amplificação de um produto com 290pb nas reações referentes aos grupos D (35 vacas) e H (25 bezerros lactentes) que, após o desmembramento em amostras individuais, resultou na identificação de 11 vacas lactantes e 12 bezerros em amamentação positivos. Para a identificação de animais persistentemente infectados (PI) entre os 23 positivos na primeira avaliação, realizou-se a segunda colheita de soros sangüíneos, três meses após. A RT-PCR das amostras individuais de soro revelou resultado positivo em cinco bezerros. Em dois, foi possível isolar o BVDV em cultivo de células MDBK. A especificidade das reações da RT-PCR foi confirmada pelo seqüenciamento dos produtos amplificados a partir do soro de uma vaca com infecção aguda, de um bezerro PI e das duas amostras do BVDV isoladas em cultivo celular. A utilização da RT-PCR em pools de soros sangüíneos demonstrou ser uma estratégia rápida de diagnóstico etiológico e de baixo custo tanto para a detecção de infecção aguda quanto de animais PI.

Abstract
The aim of this study was to establish the effects of postinfarction total or subtotal coronary occlusion on left ventricular remodeling in patients with noninsulin-dependent diabetes (NIDD) compared with the effects in postinfarct nondiabetic patients. The authors selected 100 patients submitted to coronary angiography between 1 and 5 weeks after acute myocardial infarction (T0: 20.5+/-15.4 days) and classified into three groups: G1: NIDD with coronary occlusion/subocclusion (n=24), G2: controls with coronary occlusion/subocclusion (n=43), G3: controls without coronary occlusion/subocclusion (n=33). At time zero (T0) the following parameters were evaluated: end-systolic and end-diastolic volume indexes (ESVi, EDVi), ejection fraction (EF), echocardiographic wall motion score index (WMI), presence of left ventricular aneurysm, and triple-vessel coronary disease. The frequencies of major cardiovascular events were recorded during follow-up. Significantly greater ESVi and EDVi were noted in G2 compared with G3 (P<0.0001), while no significant differences were observed between NIDD patients and controls. Although left ventricular global and segmental dysfunctions were increased in diabetics, controls with coronary occlusion/subocclusion presented more pronounced EF reduction (P<0.0001 G2 vs G3) and higher elevation in WMI (P<0.005 G2 vs G3). Cardiac events during follow-up were elevated in G1 and G2, particularly as regards the occurrence of congestive heart failure. The authors conclude that NIDD seems to influence in a positive way left ventricular remodeling associated with postinfarct total or subtotal coronary occlusion.

Abstract
The authors investigated how a previous myocardial infarction (MI) affects the prognosis of unstable angina pectoris in patients with maintained or slightly reduced left ventricular performance. From January 1991 to August 1993, 131 patients hospitalized with the diagnosis of Braunwald's class II-III unstable angina and ejection fraction > 40% were included. The enrolled patients were divided into two groups: (1) group I: unstable angina with prior MI (n = 70, 49 men, 21 women, aged between fifty-one and eighty years, mean: 65.7 +/- 8.5 years, Braunwald's class III: 71.4%), (2) group II: unstable angina with previous infarction (n = 61, 31 men, 30 women, aged between forty-nine and eighty, mean: 66.3 +/- 7.9 years, Braunwald's class III: 83.6%). The follow-up varied between six and twenty-four months. The frequency of major cardiovascular events (deaths, MI, reinfarction, heart failure, and recurrent unstable angina) and the number of revascularization procedures (percutaneous transluminal coronary angioplasty [PTCA] and coronary artery bypass grafting [CABG]) established during follow-up were evaluated. Hospitalization was 10.1 +/- 2.9 days in group I and 8.6 +/- 2.6 days in group II (P < 0.01). The duration of the follow-up was comparable between the two groups. Based upon predischarge noninvasive evaluation, patients in both groups were selected to undergo coronary and ventricular angiography: 38 of 70 (55.7%) in group I and 39 of 61 (62.3%) in group II; among them, 52.9% in group I and 24.6% in group II (P < 0.05) were submitted to coronary revascularization, while the others received medical treatments: 33 of 70 in group I and 46 of 61 in group II (P < 0.05). In the subset of patients submitted to angiography, the severity of coronary disease did not differ between the groups, and group I showed a statistically lower ejection fraction than group II (P < 0.005). The frequency of major cardiovascular events demonstrated a mortality rate of 2.9% in group I and 1.6% in group II. Acute MI/reinfarction accounted for 2.9% of the cases in group I and 3.3% in group II. Heart failure was present in 2.9% of group I. Recurrence of unstable angina was diagnosed in 11.4% of group I and 6.5% of group II. CABG and PTCA were performed, respectively in 7.1% and 5.7% in group I and in 6.6% and 4.9% in group II. During follow-up 75.7% of patients in group I and 80.3% in group II were asymptomatic. No significant differences in the frequency of cardiovascular events were reported between the two groups. As result of more aggressive therapeutic approaches following the detection of residual ischemia in patients with prior infarction, the authors conclude that the prognosis of unstable angina in the group with previous infarction does not seem to differ from that of unstable angina in the absence of prior necrosis in patients whose left ventricular function is maintained or slightly decreased.

Abstract
BACKGROUND Myocardial blood flow (MBF) impairment has been documented in advanced dilated cardiomyopathy (DCM) in which hemodynamic factors, secondary to severe ventricular dysfunction, may limit myocardial perfusion. To assess whether MBF impairment in DCM may also be present independent of hemodynamic factors, the present study was designed to quantify myocardial perfusion in patients with mild disease without overt heart failure. METHODS AND RESULTS Absolute regional MBF (milliliters per minute per gram) was measured by positron emission tomography and 13N-ammonia in resting conditions, during pacing-induced tachycardia, and after dipyridamole infusion (0.56 mg/kg over 4 minutes) in 22 DCM patients and in 13 healthy subjects. Patients were in New York Heart Association functional class I-II and showed depressed left ventricular (LV) ejection fraction by radionuclide angiography (35 +/- 8%; range, 21% to 48%), normal coronary angiography, and normal or moderately increased LV end-diastolic pressure (9.2 +/- 5.5 mm Hg; range, 2 to 20 mm Hg). There were no differences in arterial blood pressure, heart rate, and rate-pressure product between patients and control subjects in the three study conditions. Compared with control subjects, DCM patients had lower mean MBF at rest (0.80 +/- 0.25 versus 1.08 +/- 0.20 mL.min-1.g-1, P < .01), during atrial pacing tachycardia (1.21 +/- 0.59 versus 2.03 +/- 0.64 mL.min-1.g-1, P < .01), and after dipyridamole infusion (1.91 +/- 0.76 versus 3.78 +/- 0.86 mL.min-1.g-1, P < .01). LV MBF values were related to baseline LV end-diastolic pressure at rest (r = -.57, P < .01) and during pacing (r = -.67, P < .01) but not after dipyridamole infusion (r = .19, P = .40). Five patients had LV end-diastolic pressure > 12 mm Hg; in 4, myocardial perfusion was severely depressed both at baseline and in response to stress. CONCLUSIONS In patients with DCM without overt heart failure, myocardial perfusion is impaired both at rest and in response to vasodilating stimuli. The abnormalities in vasodilating capability can be present despite normal hemodynamics; progression of the disease is associated with more depressed myocardial perfusion.

Abstract
BACKGROUND Aging and diabetes mellitus have been recognized as strong predictors of heart failure in patients with acute myocardial infarction. The aim of this study was to assess, by echocardiography, the influence of aging and non-insulin-dependent diabetes mellitus on the changes of left ventricular parietal kinesis in patients with acute myocardial infarction over the 6 months after hospitalization. METHODS The study population consisted of 82 patients (42 male, 40 female) aged 70 years, consecutively admitted to coronary care unit with acute myocardial infarction from January 1991 to May 1993. They were divided into two groups: group 1 comprised 36 patients with non-insulin-dependent diabetes mellitus, aged 78.8 +/- 6.02 years, 17 men and 19 women; group 2 comprised 46 patients without diabetes aged 78.7 +/- 6.9 years, 25 men and 21 women. Echocardiography was performed at admission to the unit (T0), at discharge (T1), and after 6 months of follow-up (T2). The echocardiographic wall motion score index was calculated by considering the number of akinetic and dyskinetic left ventricular wall segments. Fatal and non-fatal incidents of heart failure were also considered and a multivariate analysis was applied to identify the clinical and instrumental parameters that were independent predictors of wall motion score index changes and heart failure events. RESULTS At T1 the two groups were comparable in localization of acute myocardial infarction, previous myocardial infarction, creatinine kinase serum peak, ECG score and wall motion score index. A statistically significant reduction in akinesia (P < 0.001) was observed in group 2 at T1 and T2, but was not seen in group 1. At T2 the difference in wall motion score index between the groups became significant (P < 0.05). The occurrence of heart failure was significantly higher in group 1 than in group 2 either during hospitalization (P < 0.03) or during follow-up (P < 0.004). The multivariate analysis identified non-insulin-dependent diabetes mellitus as an independent predictor of lacking recovery in LV kinesis (P < 0.01) and of heart failure development (P < 0.001). CONCLUSION In elderly patients with non-insulin-dependent diabetes mellitus lack of recovery in wall motion score index after acute myocardial infarction seems to be an important factor, with a higher heart failure prevalence adversely affecting the in-hospital and long-term outcome. Non-insulin-dependent diabetes mellitus appears to be an important factor related to this unfavorable outcome.

Abstract
Left ventricular hypertrophy (LVH) dramatically worsens hypertensive illness. Because the genesis of LVH appears to be multifactorial, antihypertensive treatment should aim to reduce not only pressor values but also the hypertrophic ventricular mass. This result can be obtained only when drugs able to act on both pathogenetic factors are used. To evaluate the effectiveness of antihypertensive therapy on regression of LVH, 21 patients with stage 2 essential hypertension were treated for a year with either atenolol (120 mg/d orally), a cardioselective beta-blocker without intrinsic sympathomimetic activity, or ramipril (5 mg/d orally), an angiotensin-converting enzyme inhibitor with high tissue activity. Both treatments produced significant control of hypertension and regression of LVH. No statistically significant difference between treatments was noted, except for heart rate, which was substantially unchanged by ramipril but significantly decreased by atenolol. Both drugs were well tolerated. Atenolol and ramipril have a major role in the long-term treatment of hypertension and in the regression of hypertension-associated LVH.

Abstract
From January 1992 to January 1993 the incidence of sudden cardiac death among the population of the Media Valle del Serchio area (Tuscany, Italy), composed of a population of 35,000, was found to be twice that of the European average; 32 cases have been reported over this period in that area (9 per 10,000 in the examined year), with a male/female (M/F) ratio of 2.5:1 (23 M, 9 F). In Italy the mean incidence of sudden death was calculated as 6/10,000 and in Europe 5/10,000. In the examined population hypertension was the coronary risk factor present most frequently (87%). A previous diagnosis of coronary artery disease was documented in 21 cases (66%); 5 of these exhibited previous myocardial infarction and 3 previous myocardial infarction associated with left ventricular heart failure. In 7 subjects no previous cardiovascular disorders were discovered. Prodromal symptoms had been reported in 20 cases (62%), which included chest pain in 8 and dyspnea in 8. In the examined geographic area a high prevalence of coronary artery disease was verified through the records of the Public Health Service, which documents the main causes of mortality in Tuscany, and through the hospitalization data and the services provided for ischemic heart disease at the local coronary care unit compared with the national average. Moreover, research was accomplished on physical and chemical properties of drinking water in the same area, and this revealed a very low total hardness due to the paucity of calcium and magnesium salts.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
METHODS Twenty patients with uncomplicated myocardial infarction randomized in two groups (group 1 and 2) of ten patients were investigated. Only group 1 trained four months according to a protocol of rehabilitation, whereas patients of group 2 followed their usual activity (control group). The autonomic cardiovascular function was estimated by Ewing's tests, that evaluate the variations of heart rate and blood pressure during deep breathing. RESULTS Our data showed an increase of parasympathetic tone in group 1 (Valsalva ratio 1.55 +/- 0.28 vs 1.36 +/- 0.28, p < 0.01; variation in heart rate during deep breathing 17.3 +/- 4.6 vs 13.3 +/- 4.2). The sympathetic activity tests showed no significant difference after training. On the other hand, group 2 showed no significant difference in sympathetic and parasympathetic activity. CONCLUSIONS In patients with uncomplicated myocardial infarction physical training increases the parasympathetic activity; as shown in the literature, such an increase can have clinical and prognostic importance, since improves cardiac performance and reduces the risk of sudden death from arrhythmic events.

Abstract
The objective of this trial was to evaluate whether cardiovascular vagal-sympathetic relationship, which is expected to be decreased in the elderly, can be modified by physical activity performed in advanced age. Cardiovascular autonomic function, as assessed by heart rate and arterial blood pressure during lying to standing, deep breathing, handgrip isometric stress test and Valsalva manoeuver, was estimated through Ewing's test in 10 sedentary healthy elderly subjects (mean age 68 +/- 3.1) compared to 10 long-distance runners of the same age (mean age 69 +/- 4.6). The endurance athletes, suitable for competition, had been practicing sport activity for a long time. Moreover in order to evaluate the influence of physical activity on cardiovascular response to exertion in the elderly all subjects were submitted to maximal electrocardiographic exercise test on a cycloergometer (multistage program with 30 watt x 3 min. steps). Heart rate, arterial systolic and diastolic blood pressure were recorded; double product was calculated at baseline; furthermore, total and maximal watts were recorded. For each of the parameters, Student's "t" test for independent observations was used in order to evaluate statistical differences among the two groups. Our data exhibited better results in cardiovascular reflex response due to parasympathetic (Valsalva and deep breathing test) neurovegetative modulation in the trained subjects with respect to the sedentary controls: Valsalva ratio (VR) = 2.04 +/- 0.44 vs 1.40 +/- 0.18 p < 0.001); deep breathing test (FC) = 23.6 +/- 6.2 vs 15.1 +/- 2.5 p < 0.01.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
BACKGROUND A decrease in adaptation to exertion has been observed as age progresses. Although this decline may also be affected by factors such as health conditions and age, physical inactivity related to sedentary behaviour plays a dominant role. METHODS In order to evaluate the influence of physical activity on cardiovascular response to exertion in the elderly, 4 groups of 22 subjects each were submitted to maximal electrocardiographic exercise test on a cycloergometer (multistage program with 30 Watts x 3 min. steps). All subjects were male. The composition of the groups was as follows: 1) veteran long distance runners (mean age: 71 +/- 5.4); 2) sedentary veterans (mean age: 69.8 +/- 3.9); 3) young long distance runners (mean age: 25.4 +/- 4.3); 4) sedentary young adults (mean age: 25.8 +/- 3.9). The endurance athletes, well fitted to competition, had been practicing sport activity for at least 3 years. RESULTS Heart rate, arterial systolic and diastolic blood pressure were recorded; mean blood pressure and double product were calculated at baseline and at the climax of the stress test; furthermore, total and maximal watts were recorded. For each of the parameters, Student's t test for non-paired observations were used to evaluate statistical differences amongst the four groups. The most interesting result arises in the comparison between veteran long distance runners and sedentary young adults: between the two groups no statistically significant differences in workload, expressed as total watts (1649.55 +/- 296.32 vs 1650.00 +/- 446.32; p = NS) and maximal watts (175.91 +/- 19.19 vs 173.18 +/- 24.38; p = N.S.), were observed. On the contrary, highly significant differences in both total (p < 0.01) and maximal (p < 0.01) watts were noticed by comparing long distance runners and sedentary subjects of the same age. CONCLUSIONS These data support the hypothesis that the progressive reduction in physical activity, which is usually observed in aging, is the major determinant of exercise deconditioning in the elderly.

Abstract
The authors studied the cardiovascular effects of amitriptyline at therapeutic plasma concentrations in 15 depressed patients (6 M. 9 F.) without cardiovascular disease both before treatment and after six months of therapy. The cardiovascular effects were evaluated by means of electrocardiographic and 2D-echocardiographic examinations in basal conditions and after hand-grip stress test. The effects of isometric hand-grip exercise (IHG) on left ventricular size and performance were studied non invasively in all patients at rest and after 3 min. of IHG at 30% of maximum contraction. Left ventricular internal diameter was measured at end-diastole and end-systole on LV echograms, and blood pressure was measured by sphygmomanometer. Our data confirmed the depressant effect of amitriptyline even on healthy myocardium, an effect that becomes manifest only at handgrip stress with a significant reduction of ejection fraction (form 70.6 to 66.4%; p < 0.001), while ECG and arterial blood pressure did not change throughout the study. This goes to show that treatment with tricyclic antidepressants always has a latent depressant effect on myocardial contractility that becomes clinically evident under stress, as well as in subjects with heart disease and in the elderly. Hence the need to monitor left ventricular function, as well as ECG and blood pressure, and to exercise great caution in prescribing tricyclic antidepressants to subjects with a history of myocardial failure.

Abstract
Young elite athletes often show left ventricular hypertrophy, but normal values of quantitatively evaluated myocardial wall reflectivity. The aim of this study is to assess the acoustic pattern of ventricular wall reflectivity, as well as of systolic and diastolic function, in older endurance runners with increased left ventricular mass. For this purpose, 12 elite, senior isotonic athletes in full training and 11 normal, age-matched controls with sedentary life styles were studied. The following parameters were measured with a commercially available 2D echo-Doppler machine: end-diastolic diameter, diastolic septum thickness, left ventricular mass index, ejection fraction (by Teicholtz rule); peak E, peak A, E/A ratio, acceleration and deceleration time of mitral inflow velocity and isovolumic relaxation time. On-line radio frequency analysis was also performed to obtain quantitative operator-independent measurements of the integrated backscatter signal of the ventricular septum and the posterior wall. The integrated values of the radiofrequency signals were normalized for the pericardial interface and expressed in percent (% 2D-IB). In spite of the greater left ventricular mass in athletes versus normal controls (319 +/- 81 vs 225 +/- 63 g.m-2, P < 0.0005), there were no significant intergroup differences as regards end-diastolic diameter (50.7 +/- 5.1 vs 48.1 +/- 5.2 mm, P = ns), ejection fraction (75.5 +/- 9.3 vs 71.8 +/- 9.1%, P = ns), and 2D-IB of septum (22.2 +/- 6.9 vs 22.4 +/- 7.0, P = ns) and posterior wall (12.5 +/- 5.6 vs 13.1 +/- 2.8, P = ns).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This report represents the results of the culture tests for fungi carried out in the Aosta Valley region of Italy from 1984 to 1989. The pathological material consisted of cutaneous scales, hair and nails. It was possible to identify 91.8% of the isolates: out of these, 36.1% were dermatophytes, 21% were Aspergillus spp, 15.6% Deuteromycetes, 15% yeasts and 4.1% members of the family Mucoraceae. The resulting data indicate that Microsporum canis was the most wide-spread species (73.7%) among the isolated dermatophytes and keratinophilic fungi (Trichophyton rubrum, T. mentagrophytes, Epidermophyton floccosum and Scopulariopsis brevicaulis): 87.5% were isolated from hair and 65.9% from the glabrous skin. The high prevalence of M. canis as the cause of dermatomycoses is discussed. Lastly the use made of the Regional Hospital's Mycology Department by health workers is discussed.

Abstract
Echocardiographic indices of left ventricular volume and mass and electrocardiographic indices of left ventricular hypertrophy have evaluated in 25 patients with chronic aortic regurgitation and in 10 normal subjects. When the patients with aortic regurgitation were subdivided in three groups with increasing evidence of left ventricular hypertrophy, the echocardiographic measures of left ventricular dimension and mass were also found to be increased, with statistically significant differences between patients and controls and among the three groups of patients as well. A specially constructed cumulative electrocardiographic index of left ventricular hypertrophy (Sokolow and Lyon's index plus Lewis' index plus strain pattern) is correlated with the left ventricular end-diastolic diameter (r = 0.65; P less than 0.001), cross-sectional area (r = 0.65; p less than 0.001) and mass (r = 0.75; p less than 0.001) better than the isolated electrocardiographic indexes.

Abstract
The aim of the present study is to analyze variations of external cardiac work and of indices of myocardial oxygen consumption induced by upright tilting and hand-grip in volley-ball athletes (group A) in comparison with a group of normal subjects (group N). For this purpose we have used impedance cardiography, a simple, reproducible and non invasive technique, which is very reliable in evaluating both systolic time intervals and hemodynamic parameters such as stroke volume and cardiac output. No significant differences, of external cardiac work, double and triple product were observed between group A and N upon upright tilting. Hand-grip test, on the other hand, can differentiate the myocardial behaviour of trained people from that of the control group. The double product was significantly reduced in group A in comparison with group N (P less than 0.001 and the end of the test, P less than 0.05 after 30", P less than 0.001 after 1' and 3"). The triple product was significantly reduced in group A in comparison with group N at the end of the test (P less than 0.005). External cardiac work was always higher in group A in comparison with group N (P less than 0.02, at the stop P less than 0.05 after 30", P less than 0.01 after 1', P less than 0.0001 after 3'). Therefore in volleyball athletes the myocardium exhibits better mechanical performance than in normal subjects.
