Abstract
Background After an embolic stroke of undetermined source (ESUS), long-term monitoring is recommended to start an anticoagulation therapy in patients with documented atrial fibrillation (AF). Literature is sparse about the AF burden following an ESUS, although this might have significant implications in terms of clinical management and therapeutic strategy. Our primary aim was to evaluate a possible association between early detection of AF (within 90 days from the ILR implantation) and higher AF burden. Methods This is a retrospective single-center study of 129 consecutive patients who received implantable loop recorders (ILRs) after an ESUS for detection of subclinical AF and their AF burden. Results Mean age was 70.3 ± 10.4 years old (males: 51.9%). Atrial fibrillation was found in 40.3% of patients. Patients with AF were older, presented a higher CHAD2S2-Vasc Score and greater left atrial volume compared with patients without AF. The median AF burden was 1.2%; 59% of patients had the first AF episode within 90 days from the ILR implant while 41% experienced the first episode later than 90 days. The AF burden was significantly higher in the former group. Of note, the univariate analysis showed that only early AF detection was significantly associated with AF burden >1% (OR 20.0; 95% CI 1.68-238.6, p = 0.01). Conclusions The early AF detection was found to be significantly associated with a higher burden of AF.

Abstract
Abstract
Background
After a cryptogenic stroke, long-term monitoring is recommended to start an anticoagulation therapy in patients with at least a documented paroxysm of subclinical atrial fibrillation (AF). Literature is sparse about the recurrence of AF (AF burden) after a cryptogenic stroke, but this might have significant implications in terms of therapeutic strategy.
Methods
This is a retrospective single-center study of 129 patients who received implantable loop recorders (ILRs), after a cryptogenic stroke, between March 2015 and March 2022. All patients were followed through remote monitoring for at least 6 months. The primary endpoint was AF detection; the secondary endpoints were the AF burden, the earliness (within or after 90 days from the ILR implant) of the first AF episode and if there was an association between these two variables.
Results
Mean age was 70.3 ± 10.4 years old (67 males, 51.9%); the mean value of left ventricular ejection fraction was 61% ± 5.8. Atrial fibrillation has been detected by ILR in 40.3% of patients (AF= 52 patients, NO AF= 77 patients) and each intracardiac electrogram was visually reviewed by two physicians. Median CHAD2S2-Vasc Score was 5 [4-6]; the median AF burden (assessed in 39 of the 52 patients) was 1.2% [0.1%-14.6%]; among these, 23 patients (59%) had the first episode within 90 days from the ILR implant versus 16 patients (41%) which experienced the first episode later than 90 days. AF burden was significantly higher in the first group (median 3.9% [1.2%-30.9%] vs 0.1% [0.03%-0.75%]; p=0.001). Of note the univariate analysis showed that both detection of the first AF episode within 90 days and echocardiographic findings of atrial disease (atrial dilation or diastolic dysfunction) were significantly associated with AF burden > 1% (about 7 hours for month) (respectively OR 16.5; 95% IC=3.34-81.21, p=0.001 and OR 4.5; 95% IC=1.2-17.5, p=0.03); at the multivariate analysis the significance was confirmed for the earliness of the first AF episode (OR 14.6; 95% IC=2.8-76.75, p=0.002).
Conclusion
In this small, retrospective study, AF was detected by ILR, after a cryptogenic stroke, in more than one third of patients. AF onset during the first 90 days might be a marker of a high AF burden and might highlight patients who could benefit from a rhythm control strategy of AF. Larger studies and clinical outcomes evaluation of these patients are required to confirm our results.

Abstract
AIMS The increasing volume of pacemaker (PM) and implantable cardioverter defibrillator (ICD) implants and problems related to their functioning have highlighted the issue of device follow-ups. Patients' convenience regarding device visits has been little investigated. This work aims at surveying patients' efforts in attending the in-office PM/ICD follow-ups and at evaluating their expectations. METHODS AND RESULTS In four Italian referral centres, over a 3-month period, a 20-point questionnaire was completed by all consecutive patients at in-hospital PM/ICD visits. In total, 1109 questionnaire/patients were evaluated. Pacemakers were 68%, ICDs 16%, and cardiac resynchronizations (CRTs) (PM + ICD) 16%; 38% were females; mean age was 75 ± 11 years. Almost all were scheduled visits. There was frequent reprogramming and clinical examination, even after 6 months from implant. Perceived inconvenience for the in-office follow-up was relevant in 35% of cases; attitudes towards remote monitoring were positive in 88% of cases. Inter-group analysis showed some significant difference: PM patients were older and more frequently female; ICD carriers were younger, had the highest rate of clinical evaluation, a longer journey time, and the most positive opinion about remote follow-up. Cardiac resynchronization patients had a longer waiting time and the lowest inconvenience. Overall inconvenience was independently predicted by increasing age, lengthy travelling times, and being accompanied; favourable opinions about remote monitoring were predicted by overall inconvenience, and, in ICD carriers only, by lack of clinical examination. CONCLUSIONS Patients' perceptions of in-hospital PM/ICD visits were affected by age and by journey modalities. Individual factors seem to affect both opinions about in-office visits and expectations towards a possible remote follow-up.

Abstract
The effect of cardiac resynchronisation therapy on ventricular tachycardias (VT) has not been well established. This case-report demonstrates the favourable impact of biventricular pacing on ventricular arrhythmias. In 2004, a patient with dilated cardiomyopathy and ICD since 1999 was admitted to our Division for multiple VT. While left ventricular function was markedly reduced and mitral regurgitation was severe, he was asymptomatic for heart failure. Amiodarone was not administered on account of a documented proarrhythmic effect. The patient's ICD was upgraded to an ICD-biventricular system. After upgrading, a significant reduction in the number of VT was noted.

Abstract
The aim of this study was to evaluate the effects of chronic treatment with lacidipine on blood pressure, heart rate and double product during and immediately after physical effort in mild to moderate hypertensive patients. This was a single-center, randomized, double-blind, crossover, placebo-controlled clinical trial. Eighteen hypertensive patients (56% males, median age 53 years) were randomized to lacidipine 4 mg o.i.d. followed by placebo or to placebo followed by lacidipine 4 mg o.i.d. Lacidipine compared with placebo exerted a significant antihypertensive effect, lowering SBP and DBP both at baseline and either during or after exercise test. The average incremental changes of SBP and DBP between pre-exercise stage and maximal effort did not show any significant differences between treatments. HR during treatment with lacidipine was higher than during treatment with placebo both at rest and after exercise, but at maximal effort, HR was not different from placebo. The average values of DP at maximal effort, and during recovery, did not show any significant differences. Lacidipine 4 mg was effective in lowering blood pressure and in maintaining its antihypertensive effect throughout and after physical exercise, without enhancing double product value, which is an indirect index of myocardial oxygen consumption.

Abstract
Between January and December 1992 an epidemiological survey on the risk factors for cardiovascular disease in eighteen-year old boys during call-up has been performed in Verona. The study involved 3426 subjects: 100% of the boys coming from the metropolitan area and 65% of those coming from the non-metropolitan areas. A family history of hypertension was found in 9.54% of the subjects and a family history of myocardial infarction or sudden death was found in 4.54% of the subjects. 0.18% of the population reported diabetes and 2% hypertension. Prevalence of smoke addiction was 39.1% and in this group 17.54% smoked > or = 20 cigarettes/day. Prevalence of smoke addiction was significantly greater in the boys having one or both smoking parents (p < 0.001), in working people in respect to students (p < 0.001), in boys from metropolitan in respect to those from non-metropolitan areas (p = 0.033), and among those not practising sport activity (p < 0.001). Mean systolic and diastolic blood pressure were 130.16 +/- 13/74.48 +/- 9 mm Hg and 90th percentile was 149/87 mm Hg. Systolic and diastolic blood pressure were significantly lower in boys from metropolitan in respect to those from non-metropolitan areas and in smokers in respect to non smokers. A body mass index > or = 30 was found in 3.04% of the subjects, the body mass index being directly related to systolic and diastolic blood pressure (p < 0.001). Total cholesterol performed on a voluntary basis from capillary blood samples by Reflotron System was determined in 80.06% of the subjects. Mean blood cholesterol was 139.1 +/- 28 mg/dL and 90th percentile's value was 182 mg/dL. Mean blood cholesterol was significantly lower in non-metropolitan in respect to metropolitan areas (p = 0.033). 44.48% of the subjects had one or more risk factors, 5.22% had two risk factors and 0.67% three or more risk factors for cardiovascular disease. This study shows that 1) in this population of young people a significant part is exposed to one or more cardiovascular risk factors; 2) social and environmental factors affect, sometimes deeply, the prevalence of cardiovascular risk factors; 3) The visit for call-up appears to be important in the setting-up of a strategy of primary prevention for cardiovascular disease.

Abstract
Short-term outcome after coronary angioplasty is mainly determined by restenosis, while long-term outcome is determined by new events due to incomplete revascularization, by atherosclerosis progression and by late-restenosis. The aim of this study is to assess if correctly treated coronary risk factors are predictors of poor prognosis after coronary angioplasty. Two-hundred and twenty six patients (209 males, 17 females, mean age 56 +/- 9 years) with successful coronary angioplasty were treated for coronary risk factors. New events (death, myocardial infarction, repeat angioplasty, bypass surgery) were recorded. Ischemia was evaluated by serial exercise tests. The mean follow-up was 31 +/- 12 months. Survival was 99.5% at 1 year and 97.4% after 5 years; "event free survival" was 84.6% at 1 year and 65.9% after 5 years; "ischemia free survival" was 84.6% at 1 year and 44.8% after 5 years. "Ischemia free survival" was higher in patients with single coronary angioplasty and in patients with infarct-related vessel angioplasty. Smoke addiction, diabetes, hypercholesterolemia and hypertension were not significantly correlated with "ischemia free survival". Smokers and diabetics had a trend towards a less favorable 5 year outcome, but without statistical differences. In conclusion, this study shows that correctly treated coronary risk factors do not worsen prognosis after coronary angioplasty.

Abstract
Twenty patients (12 males, 8 females, mean age 51 +/- 10 years) with mild to moderate arterial hypertension were treated with nitrendipine (mean daily dose 17 mg) during a 6 month period. Patients were evaluated with blood measurement and with 24-hour ambulatory blood pressure monitoring. In 16 patients who completed the study, systolic and diastolic blood pressure decreased of 13-15% and 18-20% respectively after at least 1 month of therapy. Mean 24-hour blood pressure was reduced of 9.7% (p < 0.01) at the end of the third month and of 13.9% (p < 0.01) at the end of the sixth month. Both systolic and diastolic 24-hour blood pressure were significantly reduced. Nitrendipine was active on day time and night time pressure. Only 1 patient had edema of the legs. Heart rate was not increased by the drug. Total cholesterol and LDL cholesterol were reduced.

Abstract
Patients with ischemic heart disease are often affected by a mixed hyperlipoproteinemia, where a hypercholesterolemia of various severity is accompanied by slight or moderate hypertriglyceridemia (type IIb dyslipidemia). Current epidemiologic evidence suggests that hypertriglyceridemia has not to be disregarded, particularly in certain subgroups of patients. We evaluated the effect of the association of simvastatin 10 mg/day [an hydroxymethyl-glutaryl-CoA (HMG-CoA) reductase inhibitor] and omega-3 polyunsaturated fatty acids (n3-PUFA) in comparison with simvastatin 10 mg/day alone. The subjects undergoing the study were affected by coronary artery disease and showed hypercholesterolemia (LDL-cholesterol > 160 mg/dl) and moderate hypertriglyceridemia (serum triglycerides 200-400 mg/dl) after 2 months of moderate dietary therapy for hyperlipidemia (Step 1 of the National Cholesterol Education Program [NCEP]). Thirty-nine patients were randomized to have 1 of 2 scheduled treatments. At the same time the patients underwent severe dietary therapy for hyperlipidemia (Step 2 of the NCEP). After 3 months of treatment, total-cholesterol, LDL-cholesterol, and triglycerides were significantly lower than basal values in both groups (p < 0.05). Total-cholesterol, LDL-cholesterol, and triglycerides were lower in the group treated with n3-PUFA and simvastatin compared to simvastatin alone. However, only for triglycerides was the difference significant (-39.99% in patients treated with n3-PUFA and simvastatin versus -25.65% in patients treated with simvastatin alone, particularly in the first group of 35.85%; p < 0.05). With regard to HDL-cholesterol, the differences between the basal values and the 2 groups of treatments were non significant. Remarkable side effects were not observed in the 2 groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In July 1987 a prehospital emergency medical service (EMS) was activated in Verona (Italy) and a broad educational campaign was introduced. Prehospital care is delivered by emergency physicians and/or qualified nursing staff, who travel by ambulance or helicopter and have radio contact with the hospital alarm centre. During a 1-year period before the activation of the EMS, 476 patients with acute myocardial infarction (AMI) were admitted to the coronary care unit (CCU) of Verona, with a median delay time of 4 hours. In the period between July 1990 and June 1991, 412 patients were admitted, with a median delay time of 3 hours. Age, gender, previous AMI and infarct location were not related to delay time. In the second period, 34% patients used the EMS, while 66% used their own transport. In patients who used the EMS, median delay time was 2 hours (1 hour and 20 min shorter, p < 0.01, than in patients who did not). The time between symptoms onset and reaching the decision that medical care should be sought (1 hour and 18 min) was the longest component of the total delay time. The time from EMS call to hospital arrival was 25 min and the time which elapsed in the Emergency Department before reaching the CCU was 15 min. In these patients, decision time and Emergency Department time were significantly shorter (p < 0.01) than in patients who did not use the EMS. We conclude that the EMS is effective in reducing delay time in patients with AMI.

Abstract
The antihypertensive effect of the angiotensin-converting enzyme (ACE) inhibitor lisinopril administered in a single dose of 20 mg was evaluated by ambulatory blood pressure monitoring (ABPM) in a double-blind, placebo-controlled, cross-over study. Twenty-four patients (21 men and 3 women, mean age 52 +/- 6 years) with mild to moderate hypertension were included in the study and randomly assigned to two consecutive treatments with lisinopril 20 mg and placebo, each administered for 4 weeks. On the last day of each treatment, BP was assessed by noninvasive 24-h ABPM. BP was significantly lower after lisinopril than after placebo in a 24-h period (mean 24-h systolic BP (SBP) with lisinopril 120 +/- 7 mm Hg and with placebo 135 +/- 9 mm Hg; mean day SBP with lisinopril 125 +/- 3 mm Hg and with placebo 142 +/- 5 mm Hg; mean night SBP with lisinopril 112 +/- 4 mm Hg and with placebo 124 +/- 6 mm Hg; mean 24-h diastolic BP (DBP) with lisinopril 76 +/- 6 mm Hg, and with placebo 87 +/- 8 mm Hg; mean day DBP with lisinopril 80 +/- 3 mm Hg and with placebo 93 +/- 4 mm Hg; mean night DBP with lisinopril 69 +/- 2 mm Hg and with placebo 79 +/- 5 mm Hg, p less than 0.001). Mean 24-h, mean day, and mean night heart rate (HR) did not differ significantly between placebo and lisinopril treatments. Repeated-measures analysis of variance (ANOVA) showed a significant influence on SBP (p less than 0.001) and DBP (p less than 0.001) throughout the treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
With the aim of investigating the functional result of the coronary angioplasty (PTCA) and verifying the predictive value of the exercise test for detecting restenosis, 165 patients who underwent successful PTCA were evaluated through exercise stress tests performed 10, 75 and 165 days after PTCA and through coronary angiography performed 5 to 6 months after PTCA. The percentage of negative tests and the rate-pressure product (RPP) increased significantly with respect to the tests performed before PTCA, both in patients with single-vessel and those with multivessel disease. Maximal ST segment depression and ST/HR were significantly reduced only in patients with complete revascularization. The percentage of positive tests 10 days after PTCA was lower in patients with single-vessel than in those with multivessel disease (2.5% versus 10.8%) and, of the latter, in patients with complete rather than incomplete revascularization (0% versus 13.5%). In patients with complete revascularization, the mean exercise time rose significantly (703 s versus 538 s). The percentage of positive tests increased progressively with time, in accordance with probable increasing restenosis. In comparison with the results of angiography, sensitivity of the exercise stress test proved to be poor (59%), especially in patients with single-vessel disease (45%), while the specificity was very high (98%). The predictive value of a negative test was 77% in patients with multi-vessel and 87% in patients with single-vessel disease. The predictive value of a positive test was over 90% in both groups of patients.

Abstract
In 35 patients with effort angina exercise tests before and after coronary angioplasty (PTCA) were compared, aimed at evaluating functional improvement and at correlating some ergometric parameters with angiographic results. All tests were performed during therapy with verapamil 360 mg/die. After PTCA mean diameter of the stenosis was reduced from 68 +/- 11% to 19 +/- 12%. Duration of exercise and rate-pressure product (RPP) were significantly greater in the test after PTCA. While all tests before PTCA were positive, after PTCA ST segment depression occurred in 9 patients (26%). In 7 of these patients it was less than 1 mm. In 26 patients (74%) tests were negative after PTCA. In patients with ST segment depression, ischemia threshold significantly rose from 5.2 +/- 1.5 min (RPP 15,875 +/- 3,253 to 7.6 +/- 1.2 min (RPP 20,157 +/- 3143). Maximal ST segment depression and ST/HR slope were significantly reduced. In negative stress tests the time free from ischemia significantly rose from 6.5 +/- 2.6 min (RPP 18,872 +/- 3,861) to 10.5 +/- 2.3 min (RPP 28,476 +/- 4,289). In patients with positive tests stenosis after PTCA was more severe than in patients without ST segment depression (29 +/- 13% vs 17 +/- 13%). In patients with ST segment depression improvement of ischemia threshold and of stenosis were correlated. In these patients improvement of ischemia threshold is the ergometric parameter more useful to evaluate the angiographic result of PTCA.
