Результаты оригинального PIOPED опубликованы в JAMA: PIOPED investigators: Value of the ventilation-perfusion scan in acute pulmonary embolism: results of the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED). JAMA. 1990 May, 263(20):2753-9 ([Ссылки могут видеть только зарегистрированные и активированные пользователи] 4&keytype2=tf_ipsecsha)

"The Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) study (34), published in 1990, comprised 933 patients (randomly chosen from 1,493), 931 of whom had V/Q radionuclide lung scans and 755 of whom had pulmonary arteriograms obtained. Of these, 251 (33%) had PE. The likelihood of PE was related to V/Q radionuclide lung scan interpretation: 102 of 116 (88%) patients with high-probability scans had PE, 105 of 322 (33%) patients with intermediate-probability scans had PE, and 39 of 238 (16%) patients with low-probability scans had PE, but many patients with low-probability scans did not undergo arteriography and had no evidence of PE on follow-up. Therefore, approximately 12% of patients with radionuclide lung scans interpreted as low-probability for PE were considered to have had PE. The investigators concluded that (i) a high-probability scan usually indicates PE, but only a minority of patients with PE have high probability scans, (ii) a history of PE decreases the accuracy of diagnoses based on high-probability scans, (iii) a low-probability scan with strong clinical suspicion that PE is not likely makes PE a remote possibility, (iv) near-normal/normal radionuclide lung scans make the diagnosis of acute PE very unlikely (five of 131 [4%] in their series), (v) an intermediate-probability (indeterminate) scan is not of help in establishing a diagnosis, and (vi) that V/Q radionuclide lung scan combined with clinical assessment permitted noninvasive diagnosis or exclusion of acute PE for a minority of patients.

Should beta blockers remain first choice in the treatment of primary hypertension?
A meta-analysis.

BACKGROUND: Beta blockers have been used widely in the treatment of hypertension and are recommended as first-line drugs in hypertension guidelines. However, a preliminary analysis has shown that atenolol is not very effective in hypertension. We aim to substantially enlarge the data on atenolol and analyse the effect of different beta blockers.
METHODS: The Cochrane Library and PubMed were searched for beta blocker treatment in patients with primary hypertension. Data were then entered into the Cochrane Collaboration Review Manager package and were summarised in meta-analyses. 13 randomised controlled trials (n=105 951) were included in a meta-analysis comparing treatment with beta blockers with other antihypertensive drugs. Seven studies (n=27 433) were included in a comparison of beta blockers and placebo or no treatment.
FINDINGS: The relative risk of stroke was 16% higher for beta blockers (95% CI 4-30%) than for other drugs. There was no difference for myocardial infarction. When the effect of beta blockers was compared with that of placebo or no treatment, the relative risk of stroke was reduced by 19% for all beta blockers (7-29%), about half that expected from previous hypertension trials. There was no difference for myocardial infarction or mortality.
INTERPRETATION: In comparison with other antihypertensive drugs, the effect of beta blockers is less than optimum, with a raised risk of stroke. Hence, we believe that beta blockers should not remain first choice in the treatment of primary hypertension and should not be used as reference drugs in future randomised controlled trials of hypertension.

Atenolol in hypertension: is it a wise choice?

BACKGROUND: Atenolol is one of the most widely used beta blockers clinically, and has often been used as a reference drug in randomised controlled trials of hypertension. However, questions have been raised about atenolol as the best reference drug for comparisons with other antihypertensives. Thus, our aim was to systematically review the effect of atenolol on cardiovascular morbidity and mortality in hypertensive patients.
METHODS: Reports were identified through searches of The Cochrane Library, MEDLINE, relevant textbooks, and by personal communication with established researchers in hypertension. Randomised controlled trials that assessed the effect of atenolol on cardiovascular morbidity or mortality in patients with primary hypertension were included.
FINDINGS: We identified four studies that compared atenolol with placebo or no treatment, and five that compared atenolol with other antihypertensive drugs. Despite major differences in blood pressure lowering, there were no outcome differences between atenolol and placebo in the four studies, comprising 6825 patients, who were followed up for a mean of 4.6 years on all-cause mortality (relative risk 1.01 [95% CI 0.89-1.15]), cardiovascular mortality (0.99 [0.83-1.18]), or myocardial infarction (0.99 [0.83-1.19]). The risk of stroke, however, tended to be lower in the atenolol than in the placebo group (0.85 [0.72-1.01]). When atenolol was compared with other antihypertensives, there were no major differences in blood pressure lowering between the treatment arms. Our meta-analysis showed a significantly higher mortality (1.13 [1.02-1.25]) with atenolol treatment than with other active treatment, in the five studies comprising 17671 patients who were followed up for a mean of 4.6 years. Moreover, cardiovascular mortality also tended to be higher with atenolol treatment than with other antihypertensive treatment. Stroke was also more frequent with atenolol treatment.
INTERPRETATION: Our results cast doubts on atenolol as a suitable drug for hypertensive patients. Moreover, they challenge the use of atenolol as a reference drug in outcome trials in hypertension.

Evaluation of the ventricular assist device programme in the UK.

Sharples L, Buxton M, Caine N, Cafferty F, Demiris N, Dyer M, Freeman C.

MRC Biostatistics Unit, Cambridge, UK.

OBJECTIVES: To summarise the relevant clinical effectiveness and cost-effectiveness literature, to collect data on survival, transplantation rates, health-related quality of life (HRQoL) and resource use for ventricular assist device (VAD) and non-VAD transplant candidates in the UK, and to construct cost-effectiveness and cost-utility models of VADs in a UK context. Also to investigate the factors that drive costs and survival.
DESIGN: A comprehensive systematic review was carried out. Data were collected from April 2002 to December 2004, with follow-up to March 2005. Cost-effectiveness and cost-utility models of VAD devices were developed based on UK activity and outcomes collected from April 2002 to March 2005.
SETTING: National Specialist Commissioning Advisory Group funded VAD implantation was carried out at the Freeman, Harefield and Papworth transplant centres in the UK.
PARTICIPANTS: Seventy patients were implanted with a VAD as a bridge to transplantation between April 2002 and December 2004. Non-VAD-supported transplant candidates (n = 250), listed at the three centres between April 2002 and December 2004, were divided into an inotrope-dependent group (n = 71) and a non-inotrope-dependent group (n = 179). Although patients in the inotrope-dependent group were closest to the VAD group they were less sick. The last group comprised a hypothetical worst case scenario, which assumed that all VAD patients would die in the intensive care unit (ICU) within 1 month without VAD technology.
INTERVENTIONS: Patients were included who were implanted with a VAD designed for circulatory support for more than 30 days, with intention to bridge to transplantation. A multistate model of VAD and transplant activity was constructed; this was populated by data from the UK.
MAIN OUTCOME MEASURES: Survival from VAD implant or from transplant listing for non-VAD patients to 31 March 2005. Serious adverse events and quality of life measures were used. Cognitive functioning was also assessed. Utility weights were derived from EuroQoL responses to estimate quality-adjusted life-years (QALYs). Incremental cost-effectiveness ratios (ICERs) were defined as the additional cost of VADs divided by additional QALYs. Time-horizons were 3 years, 10 years and the lifetime of the patients.
RESULTS: Of 70 VAD patients, 30 (43%) died pretransplant, 31 (44%) underwent transplantation, and four (6%) recovered and had the VAD removed. Five patients (7%) were still supported for median of 279 days at the end of March 2005. Successful bridge-to-transplantation/recovery rates were consistent with published rates. Survival from VAD implantation was 74% at 30 days and 52% at 12 months. There were 320 non-fatal adverse events in 62 patients during 300 months of VAD support, mostly in the first month after implantation. Commonly observed events were bleeding, infection and respiratory dysfunction. Twenty-nine (41%) patients were discharged from hospital with a VAD. The 1-year survival post-transplantation was 84%. For the inotrope-dependent and non-inotrope-dependent transplant candidates, death rates while listed were 10% and 8% and the median waiting times were 16 and 87 days, respectively. For transplant recipients, 1-year survival was 85% and 84%, respectively. Both VAD and non-VAD patients demonstrated similar significant improvements in their New York Heart Association class after transplantation. All patients had poor EQ-5D pretransplantation; after transplantation the groups had similar EQ-5D of 0.76 irrespective of time after surgery. HRQoL was poor in the first month for VAD patients but better for those who waited longer in all groups. VAD patients reported more problems with sleep and rest and with ambulation in the first month. Symptom scores were similar in all groups pretransplant. After transplantation all groups showed a marked and similar improvement in physical and psychosocial function. Mean VAD implant cost, including device, was pound63,830, with costs of VAD support for survivors of pound21,696 in month 1 and pound11,312 in month 2. Main cost drivers were device itself, staffing, ICU stay, hospital stay and events such as bleeding, stroke and infection. For the base case, extrapolating over the lifetime of the patients the mean cost for a VAD patient was pound173,841, with mean survival of 5.63 years and mean QALYs of 3.27. Corresponding costs for inotrope-dependent patients were pound130,905, with mean survival 8.62 years and mean QALYs 4.99. Since inotrope-dependent patients had lower costs and higher QALYs than VAD patients, this group is said to be dominant. Non-inotrope-dependent transplant candidates had similar survival rates to those on inotropes but lower costs, also dominant. Compared with the worst case scenario the mean lifetime ICER for VADs was pound49,384 per QALY. In a range of sensitivity analyses this ranged from pound35,121 if the device cost was zero to pound49,384. Since neither inotrope-dependent transplant candidates nor the worst case scenario were considered fair controls the assumption was investigated that, without VAD technology, there would be a mixture of these situations. For mixtures considered the ICER for VADs ranged from pound79,212 per QALY to the non-VAD group being both cheaper and more effective.
CONCLUSIONS: There are insufficient data from either published studies or the current study to construct a fair comparison group for VADs. Overall survival of 52% is an excellent clinical achievement for those young patients with rapidly failing hearts. However, if the worst case scenario were plausible, and one could reliably extrapolate results to the lifetime of the patients, VADs would not be cost-effective at traditional thresholds. Further randomised controlled trials are required, using current second generation devices or subsequent devices and conducted in the UK.
