Home-based telerehabilitation in older patients with chronic obstructive pulmonary disease and heart failure: a randomised controlled trial

Background

chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) frequently coexist in older people, reducing patients' quality of life (QoL) and increasing morbidity and mortality.

Objective

we studied the feasibility and efficacy of an integrated telerehabilitation home-based programme (Telereab-HBP), 4 months long, in patients with combined COPD and CHF. The primary outcome was exercise tolerance evaluated at the 6-min walk test (6MWT). Secondary outcomes were time-to-event (hospitalisation and death), dyspnoea (MRC), physical activity profile (PASE), disability (Barthel) and QoL (MLHFQ and CAT).

Study design

randomised, open, controlled, multicenter trial.

Methods

the Telereab-HBP included remote monitoring of cardiorespiratory parameters, weekly phone-calls by the nurse, and exercise programme, monitored weekly by the physiotherapist. All outcomes were studied again after 2 months of a no-intervention period.

Results

in total, 112 patients were randomised, 56 per group. Their mean (SD) age was 70 (9) years, and 92 (82.1%) were male. After 4 months, the IG were able to walk further than at baseline: mean (95% CI) Δ6MWT was 60 (22.2,97.8) m; the CG showed no significant improvement: -15 (-40.3,9.8) m; P = 0.0040 between groups. In IG, the media time to hospitalisation/death was 113.4 days compared with 104.7 in the CG (P = 0.0484, log-rank test). Other secondary outcomes: MRC (P = 0.0500), PASE (P = 0.0015), Barthel (P = 0.0006), MLHFQ (P = 0.0007) and CAT (P = 0.0000) were significantly improved in the IG compared with the CG at 4 months. IG maintained the benefits acquired at 6 months for outcomes.

Conclusions

this 4-month Telereab-HBP was feasible and effective in older patients with combined COPD and CHF.

Comparison of Low-Dose Statin Versus Low-Dose Statin + Armolipid Plus in High-Intensity Statin-Intolerant Patients With a Previous Coronary Event and Percutaneous Coronary Intervention (ADHERENCE Trial)

Low-density lipoprotein cholesterol (LDL-C) reduction is associated with a significant decrease in mortality, and statins represent the most effective drugs to achieve this. However, side effects of statins are very common and may lead to treatment discontinuation. Nutraceuticals are a combination of natural components that have shown efficacy in lowering LDL-C concentration when used alone or in association with other agents in patients who are intolerant to high-dose statins. Our aim was to compare the efficacy and tolerability of low-dose statin (LDS) therapy versus combined therapy of LDS plus a nutraceutical combination containing red yeast rice, policosanol, berberine, folic acid, coenzyme Q10 and astaxanthin (Armolipid Plus) in high-risk patients. We performed a randomized (1:1), prospective, parallel group, single-blind trial in which participants had coronary artery disease (n = 100), had undergone percutaneous coronary intervention in the preceding 12 months, were high-dose statin intolerant, and did not achieve ≥50% reduction in LDL-C with LDS treatment alone. After 3 months, patients in the LDS + Armolipid Plus (n = 50) group presented with a significantly greater reduction of LDL-C and total cholesterol (p <0.0001), and 70% of patients in this group achieved the therapeutic target (LDL-C <70 mg/dl), whereas patients in the LDS group did not. Six patients (3 from each group) dropped out due to myalgia. In conclusion, in patients with coronary artery disease and high-dose statin intolerance, the combination of LDS and nutraceuticals represents a valuable therapeutic option.

Greater cardiovascular risk reduction with once-daily fixed combination of three antihypertensive agents and statin versus free-drug combination: The ALL-IN-ONE trial

BACKGROUND

The ultimate goal of antihypertensive therapy is cardiovascular risk (CVR) reduction. The aim of this study was to compare the efficacy and safety of once-daily fixed combination (ODFC) versus free-drug combination (FDC) of 3antihypertensive agents and statin.

METHODS

The ALL-IN-ONE trial was a 12-week randomized, prospective, multicenter trial. A total of 305 hypertensive patients were randomized 1:1. The "fixed group" was given an ODFC of perindropil 10mg plus indapamide 2.5mg plus amlodipine 5 or 10mg plus atorvastatin 20mg. The "free group" was given a FDC of the 3antihypertensive agents plus atorvastatin 20mg. Primary end-points were the differences in clinic BP, cholesterol levels and CVR risk between the 2 groups after treatments. Secondary end-points included intragroup differences in clinic BP. Safety and compliance were also assessed.

RESULTS

At 12-weeks, the fixed group had lower systolic BP and similar diastolic BP compared to the free group. BP targets at week 12 were more commonly reached with fixed than free combination (89% and 80% respectively, p=0.048). For cholesterol serum in both groups there was a significant reduction of values. Also CVR reduction was greater in those taking ODF. Safety was not significantly different between the 2 groups. Conversely, compliance was significantly greater in the fixed-group vs. the free-group.

CONCLUSION

This randomized trial shows that ODF combination of perindropil, indapamide and amlodipine is as safe as free combination of the 3 drugs, but is associated with a greater efficacy in BP control, compliance and, associated with statin, in cholesterol reduction. A better cardiovascular risk control is achieved with ODF combination than with a free administration. ClinicalTrials.gov ID: NCT02710539.

Usefulness of Nutraceuticals (Armolipid Plus) Versus Ezetimibe and Combination in Statin-Intolerant Patients With Dyslipidemia With Coronary Heart Disease

Statins are extensively used to treat dyslipidemia, but, because of their low tolerability profile, they are discontinued in a significant proportion of patients. Ezetimibe and nutraceuticals have been introduced as alternative therapies and have proved to be effective and well tolerated. A single-blind, single-center, randomized, prospective, and parallel group trial comparing a combination of nutraceuticals (red yeast rice, policosanol, berberine, folic acid, coenzyme Q10 and astaxanthin), called Armolipid Plus, and ezetimibe for 3 months in terms of efficacy and tolerability. Patients who did not achieve their therapeutic target (low-density lipoprotein cholesterol <100 mg/dl) could add the alternative treatment on top of randomized treatment for another 12 months: 100 patients who are dyslipidemic with ischemic heart disease treated with percutaneous coronary intervention were enrolled (ezetimibe n = 50, nutraceutical n = 50). Efficacy (lipid profile) and tolerability (adverse events, transaminases, and creatine kinase) were assessed after 3 and 12 months. After 3 months, 14 patients in the nutraceutical group achieved their therapeutic target, whereas none of the patients in the ezetimibe group did. At 1-year follow-up, 58 patients (72.5%) of the combined therapy group (n = 86) and 14 (100%) of the nutraceutical group reached the therapeutic goal. No patients experienced important undesirable effects. In conclusion, nutraceuticals alone or in combination with ezetimibe are well tolerated and improve the lipid profile in statin-intolerant patients with coronary heart disease. Further studies are needed to assess long-term effects of nutraceuticals on mortality.

Observational study on Takotsubo-like cardiomyopathy: clinical features, diagnosis, prognosis and follow-up

OBJECTIVES

The present study attempts to identify appropriate elements that may contribute to clarify the broad clinical features (diagnosis, care, complication and prognosis) of Takotsubo-like cardiomyopathy for improving its management.

DESIGN STUDY

Observational study.

SETTING

Primary level of care referred to the emergency department of Vannini Hospital, Rome, Italy.

PARTICIPANTS

The study population consisted of 75 patients, 72 of the them were women and 3 were men with a mean age of 71.9±9.6 years.

METHODS

From February 2004 to November 2010, prospectively included 84 consecutive patients diagnosed for suspected Takotsubo-like cardiomyopathy. To be eligible, patients had to meet all the Mayo clinic criteria in the absence of neurological trauma or intracranial haemorrhage. Moreover, those patients that at follow-up still presented alteration of acute phase at ECG and echocardiogram were excluded. Thus, 75 patients comprised the study population. To follow-up 19 patients were lost.

RESULTS

None of 75 patients died in acute phase. All patients were promptly discharged (8.4±4.4 days), since they recovered their normal functional status without symptoms. Follow-up information was available for 56 patients. At a mean follow-up time of 2.2±2 years (range, 0.1-6.8 years) two octogenarian patients (2.6%) died because of sudden cardiac death and pulmonary embolism, respectively. The Takotsubo-like cardiomyopathy recurred in one patient.

CONCLUSIONS

The results of this study support the previous reports about the good prognosis, also in critically ill patients, of Takotsubo-like cardiomyopathy. Further assessment will be needed to determine a careful and sustained follow-up for choosing the best care and foreseeing the recurrences of this emerging condition.

Transnasal transesophageal echocardiography: a new approach for the PFO occlusion in awake patients

OBJECTIVES

To reduce risks, discomfort, cost, and operative time for percutaneous patent foramen ovale (PFO) closure, we propose to perform this procedure under transesophageal echo-guidance using a 10 Fr. catheter introduced through nasal way (TEENW).

BACKGROUND

Transesophageal or intracardiac echocardiography is commonly used to guide percutaneous PFO closure. Sedation needed quite frequently during transesophageal echocardiography, increased patients' discomfort, procedure prolongation, costs, use of both femoral veins, and additional intracardiac manipulations are the main limitations of standard techniques.

METHODS

We enrolled 20 consecutive patients with a history of cerebral ischemia and PFO with right-to-left shunt. In 15 patients Amplatzer PFO occluder was used, whereas in five patients with longer PFO tunnel (>10 mm) Cardia Intrasept was selected. Without sedation, a multifrequency monoplane probe, developed for intracardiac echocardiography, was introduced into the nostril and advanced forward the esophagus. Then under echo guidance, the closing device was presented, opened and released.

RESULTS

Procedure lasted for an average of 33.3 min, and no complications were seen. At procedure's completion, six patients showed persistence of reduced shunt during Valsalva manoeuvre. At six-month follow-up, shunts disappeared in all patients.

CONCLUSION

TEENW is safe and well tolerated, and images' quality is high enough to deserve widespread adoption of this technique for PFO closure.

Transesophageal echocardiography through nasal way as a guide to percutaneous closure of patent foramen ovale

Percutaneous device closure of patent foramen ovale (PFO) has become an effective and safe alternative to medical or surgery treatment. Transesophageal echocardiography (TEE), as commonly used to guide this procedure, has the limitation to require general anesthesia. Recently, intracardiac echocardiography (ICE) with AcuNav probe was used to guide percutaneous PFO closure. We report a 42 year-old man with two previous cryptogenetic strokes in whom both diagnosis and guidance of PFO closure were performed by means of TEE using the AcuNav catheter introduced through nasal way (TEENW). This technique, that does not require general anesthesia, provided adequate and complete view of the Amplatzer procedure. TEENW might offer a feasible and equivalent echocardiographic alternative either to standard TEE or ICE as a guide to percutaneous PFO closure.
