Role of telecardiology in the assessment of angina in patients with recent acute coronary syndrome

We compared two models of assistance (telecardiology versus usual care) for patients discharged after acute coronary syndrome (ACS), in the assessment of angina. Two hundred patients were randomized into two groups at discharge for ACS: Group A to telecardiology and Group B to usual care. Early hospital readmission (in the first month) occurred in 16 patients (seven in Group A and nine in Group B). Six of Group A were readmitted for a cardiac cause (non-cardiac in one). Angina was the only cardiac cause. Five of the Group B patients were readmitted for a cardiac cause (non-cardiac in four). The results of the present study emphasize that patients with ACS suffer from a definite rate of cardiac symptoms within the first month (63%). Angina occurs more frequently within the first two weeks (68% of cases). Telecardiology slightly reduces hospital readmissions (telecardiology 44% versus usual care 56%), but better identifies true angina.

[The management of syncope in the hospital: the OESIL Study (Osservatorio Epidemiologico della Sincope nel Lazio)]

BACKGROUND

While syncope is generally considered a frequent finding in clinical practice, no clear epidemiological evidence is available about the relevance of such an event in the general population of Italy.

METHODS

The OESIL Study was designed and undertaken in 15 hospitals of the Italian region of Latium in order to assess the percentage of emergency-room visits and admissions due to syncope, as well as to analyze the in-hospital diagnostic work-up performed for this condition.

RESULTS

During a two-month observation period, 781 (372 males and 409 females, mean age 55.2 (22.8 years) consecutive patients came to the emergency rooms of the 15 hospitals included in the investigation due to a syncope spell (0.9% of emergency room visits); 450/781 patients (57.6%) were subsequently hospitalized (1.3% of all admissions): 48.0% of the admissions were admitted to a general medical ward, 29.3% to an observation ward, 13.3% to a cardiology section, 1.6% to a neurology section and 7.8% to other clinical sections (neurosurgery, general surgery). The mean duration of in-hospital stay was 6.9 (5.8 days; range 1-40 days). During the hospitalization period, 93.1% of patients underwent an ECG, 51.0% an EEG, 44.3% a CT scan of the central nervous system, 40.2% an echocardiogram and 19.5% a tilt-test. The syncope spell was considered to have a cardiovascular origin in 33.8% of the cases and a non-cardiovascular in 11.6% of the cases, while the origin was unknown in 54.4% of the cases.

CONCLUSIONS

Collected data support the idea that syncope represents a frequent event in the general population and is responsible for a significant percentage of emergency-room visits and hospital admissions. However, the performance of conventional diagnostic work-ups is far from being satisfactory.

[Outpatient management program of patients with chronic heart failure]

Hospitalization of patients with heart failure is often caused by poor adherence to drug therapy, by suboptimal utilization of ACE inhibitors and beta-blockers, and by the lack of systematic monitoring of patients after discharge. The aim of the study is to verify the impact of an outpatient management program on the hospitalization rate and functional status of patients with chronic heart failure. Over a five-year period, 435 patients entered our outpatient management program, which includes adjustment in medical therapy, patient education and visits timed according to the patient's status. Fifty-six percent of the patients were in New York Heart functional class I-II; 74% were male; mean age was 62 +/- 11 years. Heart failure was due to coronary heart disease in 42%, dilated cardiomyopathy in 35%, hypertensive heart disease in 13%, other etiologies in 10%. The following changes in medical therapy were made compared to the period before referral: ACE inhibitors in 88% of the patients vs 70% (p < 0.05), mean dose of enalapril and captopril respectively 18 +/- 6 mg vs 11 +/- 4 mg (p < 0.05) and 89 +/- 28 mg vs 61 +/- 34 mg (p < 0.05); digoxin in 71 vs 70% (NS); furosemide in 90 vs 87%; beta-blockers in 16 vs 6% (p < 0.05); amiodarone in 24 vs 16% (p < 0.05); oral anticoagulants in 22 vs 12% (p < 0.05); calcium channel blockers in 10 vs 16% (p < 0.05). During the follow-up period (35 +/- 11 months), there were 111 hospital admissions compared to 518 during the year before recruitment (p < 0.05). Seventy-two patients died (65 for cardiac causes) and four patients underwent cardiac transplantation. Functional status improved (301 patients in I-II functional class and 56 in III-IV after referral compared to 225 and 132 before referral, respectively). Our results were obtained through adjustment in pharmacological therapy, intensive patient education and therapeutic continuity made possible by our outpatient heart-failure clinic organization. It is likely that the increase in costs due to therapeutic adjustment and to the increase in the number of visits is counterbalanced by the reduced rate of hospital admissions.
