The effect of sitting baduanjin in patients with ST-segment elevation acute myocardial infarction after percutaneous coronary intervention: A quasi-experimental study.

BACKGROUND: Early cardiac rehabilitation plays a crucial role in the recovery of patients with ST-segment elevation acute myocardial infarction (STEMI) following percutaneous coronary intervention (PCI). This study sought to determine the effect of a program of sitting Baduanjin exercises on early cardiac rehabilitation. OBJECTIVE: The goal of this study was to investigate the effects of sitting Baduanjin exercises on cardiovascular and psychosocial functions in patients with STEMI following PCI. METHODS: This quasi-experimental study employed a randomized, non-equivalent group design. Patients in the intervention group received daily sitting Baduanjin training in addition to a series of seven-step rehabilitation exercises, whereas those in the control group received only the seven-step rehabilitation training, twice daily. Differences in heart rate variability (HRV) indicators, exercise capacity (Six-Minute Walking Distance; 6-MWD), anxiety (Generalized Anxiety Disorder-7; GAD-7), and depression (Patient Health Questionnaire-9; PHQ-9) between the two study groups during hospitalization were analyzed. RESULTS: Patients in the intervention group exhibited lower rates of abnormalities in the time domain and frequency domain parameters of HRV. The median scores of GAD-7 and PHQ-9 in both groups were lower than those at the time of admission, with the intervention group exhibiting lower scores than the control group (P < 0.001; P < 0.001, respectively). The 6-MWD after the intervention was greater in the intervention group compared to the control group (P = 0.014). CONCLUSIONS: We found that sitting Baduanjin training has the potential to enhance HRV, cardiac function, and psychological well-being in patients with STEMI after PCI. This intervention can potentially improve the exercise capacity of a patient before discharge.

Reperfusion Strategies in Acute Myocardial Infarction: State of the Art

Abstract ST elevation myocardial infarction (STEMI) is a highly prevalent condition worldwide. Reperfusion therapy is strongly associated with the prognosis of STEMI and must be performed with a high standard of quality and without delay. A systematic review of different reperfusion strategies for STEMI was conducted, including randomized controlled trials that included major cardiovascular events (MACE), and systematic reviews in the last 5 years through the PRISMA ( Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology. The research was done in the PubMed and Cochrane Central Register of Controlled Trials databases, in addition to a few manual searches. After the exclusion criteria were applied, 90 articles were selected for this review. Despite the reestablishment of IRA patency in PCI for STEMI, microvascular lesions occur in a significant proportion of these patients, which can compromise ventricular function and clinical course. Several therapeutic strategies - intracoronary administration of nicorandil, nitrates, melatonin, antioxidant drugs (quercetin, glutathione), anti-inflammatory substances (tocilizumab [an inhibitor of interleukin 6], inclacumab, P-selectin inhibitor), immunosuppressants (cyclosporine), erythropoietin and ischemic pre- and post-conditioning and stem cell therapy - have been tested to reduce reperfusion injury, ventricular remodeling and serious cardiovascular events, with heterogeneous results: These therapies need confirmation in larger studies to be implemented in clinical practice

Beneficial Effects of Baduanjin Exercise on Left Ventricular Remodelling in Patients after Acute Myocardial Infarction: an Exploratory Clinical Trial and Proteomic Analysis.

BACKGROUND: The beneficial effects of physical exercise on cardiac remodelling improvement after myocardial infarction have already been suggested. However, the results of previous clinical trials have not been consistent. Moreover, the putative molecular mechanisms leading to the clinically observed effects of physical exercise still remain elusive. AIM: We aimed to evaluate whether the well-defined and strictly controlled traditional Chinese Qigong Baduanjin exercise (BE) would attenuate the adverse left ventricular (LV) remodelling in patients with ST-elevation myocardial infarction (STEMI). METHODS: A total of 110 clinically stable STEMI patients, following successful revascularization of their infarcted coronary arteries, were randomized and enrolled in two groups: 56 were subjected to a 12-week BE-based cardiac rehabilitation programme (BE group), and the remaining 54 were exposed to the usual physical exercise (control group) for the same time period. The primary outcome was the change from baseline to 6 months in the echocardiographic LV end-diastolic volume index (ΔLVEDVi). Proteomic analysis was also performed to uncover associated mechanisms. RESULTS: Compared with the control group, the BE group showed significantly lower ΔLVEDVi (-5.1 ± 1.1 vs. 0.3 ± 1.2 mL/m2, P < 0.01). Proteomic analysis revealed BE-induced variations in the expression of 80 proteins linked to regulation the of metabolic process, immune process, and extracellular matrix reorganization. Furthermore, correlation analyses between the validated serum proteomes and primary endpoint demonstrated a positive association between ΔLVEDVi and MMP-9 expression, but a negative correlation between ΔLVEDVi and CXCL1 expression. CONCLUSION: This is the first study indicating that BE in STEMI patients can alleviate adverse LV remodelling associated with beneficial energy metabolism adaptation, inflammation curbing, and extracellular matrix organization adjustment.

[Safety and efficacy of early discharge and outpatient rehabilitation after myocardial infarction for low-risk patients]. / Sicurezza ed efficacia della dimissione precoce associata a riabilitazione ambulatoriale dopo infarto miocardico nel paziente a basso rischio.

BACKGROUND: Guidelines recommend early discharge and rehabilitation after ST-elevation myocardial infarction (STEMI) in low-risk patients. However, low risk is not established according to well-defined criteria and often it depends on subjective judgment. The aim of this real-life study is to confirm that early discharge is safe in patients at low risk according to selected criteria and subsequent outpatient rehabilitation is associated with clinical benefits. METHODS: Patients with STEMI treated with primary percutaneous coronary intervention from October 2010 to October 2017, identified as being at low risk (according to predefined criteria), discharged by day 5, were studied retrospectively. Basal characteristics and 30-day outcome were evaluated and a comparison was made between patients who completed or did not complete outpatient rehabilitation. RESULTS: We enrolled 193 STEMI patients treated with percutaneous coronary intervention for STEMI, early discharged and at low risk: 132 completed outpatient rehabilitation and 61 did not. The increase in cardiac enzymes and the occurrence of arrhythmias were the only independent predictors of completion of outpatient rehabilitation. After 30 days from discharge, adverse events were rare and not significantly different between groups. Optimal pharmacological therapy was achieved more often in the rehabilitation group (58.3% vs 44.3%; p<0.05). CONCLUSIONS: Early discharge within 5 days of STEMI has been proved feasible and safe in our population of well-defined low-risk patients. Early participation in a rehabilitation program was associated with a more adequate titration of therapy.

Effectiveness of Cardiac Rehabilitation in Exercise Capacity Increase in Patients with ST-Segment Elevation Myocardial Infarction.

Background: The efficacy of interventions in ST-segment elevation myocardial infarction (STEMI) assessed by a decrease in inpatient mortality in Poland is very high. However, a rise in mortality rate is recorded within 3 years of the discharge from the intervention centre. In order to reduce out-of-hospital mortality, the treatment should be continued with cardiac rehabilitation after hospitalization. The aim of this retrospective study was to evaluate the effect of cardiac rehabilitation on exercise capacity increase patients with STEMI with regard to their age, gender, Body Mass Index (BMI), ejection fraction (EF), concomitant diabetes and nicotine dependence. The effectiveness of cardiac rehabilitation was assessed by exercise ECG (electrocardiogram) stress test or the 6-min walk test, prior to and after cardiac rehabilitation completion. Methods: The study group included 100 randomly selected patients undergoing cardiac rehabilitation after STEMI, aged 40-75 years, with BMI ≤ 40 kg/m2, with controlled arterial hypertension, without anemia and any pulmonary comorbidities. Results: The study patients' exercise capacity was observed to have increased significantly (+1 metabolic equivalent (MET) in exercise ECG stress test and +75.4 m in the 6-min walk test) regardless of their gender, age, BMI and nicotine dependence. Conclusions: This study proved that every patient with STEMI could benefit from cardiac rehabilitation. Nicotine-dependents, males, patients aged ≤55 and those with reduced EF (<50%) were found to have benefitted most substantially.

Effect of Cardiac Rehabilitation on Outcomes in Patients with ST-Elevation Myocardial Infarction.

PURPOSE: Whether cardiac rehabilitation (CR) improves clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) has not been thoroughly evaluated. Moreover, few studies have sought to identify patients who would benefit most from CR among STEMI patients. MATERIALS AND METHODS: Consecutively, 265 STEMI patients who underwent primary PCI with implantation of DESs and follow-up angiography were examined. Seventy-six patients (30%) who received CR were assigned to the CR+ group. Another 178 patients (70%) who did not participate in CR were assigned to the CR- group. Second generation DESs were implanted in 238 (94%) patients. RESULTS: Major adverse cardiovascular events (MACEs), including death, myocardial infarction, and revascularization, were compared. The CR+ group tended to have lower MACE than the CR- group at 3 years, although the difference was not statistically significant (9.9% vs. 18.3%, hazard ratio=0.54, p=0.138). Subgroup analysis revealed a significant interaction according to CR and preprocedural thrombolysis in myocardial infarction (TIMI) flow (p value for interaction=0.011). In patients with low preprocedural TIMI flow (TIMI flow ≤1, n=161), those in the CR+ group had significantly lower MACE than those in the CR- group (p=0.005), whereas MACE was not different among patients with higher TIMI flow (TIMI flow ≥2, n=93). CONCLUSION: CR including exercise training was associated with lower MACE, particularly in patients with lower preprocedural TIMI flow during primary PCI for STEMI in the current DES era.

Outcome associated with prescription of cardiac rehabilitation according to predicted risk after acute myocardial infarction: Insights from the FAST-MI registries.

BACKGROUND: Cardiac rehabilitation is strongly recommended in patients after acute myocardial infarction. AIMS: To assess cardiac rehabilitation prescription after acute myocardial infarction according to predicted risk, and its association with 1-year mortality, using the FAST-MI registries. METHODS: We used data from three 1-month French nationwide registries, conducted 5 years apart from 2005 to 2015, including 13130 patients with acute myocardial infarction admitted to coronary or intensive care units. Atherothrombotic risk stratification was performed using the Thrombolysis In Myocardial Infarction Risk Score for Secondary Prevention (TRS-2P). Patients were classified into three categories: Group 1 (low risk; no or one risk indicator; score of 0 or 1); Group 2 (intermediate risk; two risk indicators; score of 2); and Group 3 (high risk; at least three risk indicators; score of≥3). RESULTS: Among the 12291 patients, cardiac rehabilitation prescription was 43.6% (49.9% in Group 1; 43.0% in Group 2; 35.2% in Group 3). Using Cox multivariable analysis, cardiac rehabilitation prescription was associated with lower mortality at 1 year in the overall population (3.8% vs. 8.2%; hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.61-0.85; P<0.001). Cardiac rehabilitation was associated with improved 1-year mortality, with homogeneous relative risk reductions in low- and intermediate-risk categories (HR 0.70, 95% CI 0.51-0.94) compared with high-risk patients (HR 0.72, 95% CI 0.59-0.88). In absolute terms, however, mortality decrease associated with cardiac rehabilitation was positively correlated with risk level (Group 1, 0.9% vs. 2.4%; Group 2, 3.0% vs. 4.2%; Group 3, 10.5% vs. 17.3%). CONCLUSION: Cardiac rehabilitation prescription was inversely correlated with patient risk. A positive association between cardiac rehabilitation and 1-year survival after acute myocardial infarction was present whatever the risk level, but the greatest mortality reduction was observed in high-risk patients.

Mechanical complications in patients with ST-segment elevation myocardial infarction: A single centre experience.

BACKGROUND: The study aims to assess characteristics and outcomes of patients suffering a mechanical complication (MC) after ST-segment elevation myocardial infarction (STEMI) in a contemporary cohort of patients in the percutaneous coronary intervention era. METHODS AND RESULTS: This retrospective single-center cohort study encompasses 2508 patients admitted with STEMI between March 9, 2009 and June 30, 2014. A total of 26 patients (1.1%) suffered a mechanical complication: ventricular septal rupture (VSR) in 17, ventricular free wall rupture (VFWR) in 2, a combination of VSD and VFWR in 2, and papillary muscle rupture (PMR) in 5 patients. Older age (74.5 ± 10.4 years versus 63.9 ± 13.1 years, p < 0.001), female sex (42.3% versus 23.3%, p = 0.034), and a longer latency period between symptom onset and angiography (> 24h: 42.3% versus 16.2%, p = 0.002) were more frequent among patients with MC as compared to patients without MC. The majority of MC patients had multivessel disease (77%) and presented in cardiogenic shock (Killip class IV: 73.1%). Nine patients (7 VSR, 2 VFWR & VSR) were treated conservatively and died. Out of the remaining 10 VSR patients, four underwent surgery, three underwent implantation of an occluder device, and another three patients had surgical repair following occluder device implantation. All patients with isolated VFWR and PMR underwent emergency surgery. At 30 days, mortality for VSR, VFWR, VFWR & VSR and PMR amounted to 71%, 50%, 100% and 0%, respectively. CONCLUSIONS: Despite advances in the management of STEMI patients, mortality of mechanical complications stays considerable in this contemporary cohort. Older age, female sex, and a prolonged latency period between symptom onset and angiography are associated with the occurrence of these complications.

eHealth to improve patient outcome in rehabilitating myocardial infarction patients.

INTRODUCTION: Cardiac rehabilitation is aimed at risk factor modification and improving quality of life. eHealth has a couple of potential benefits to improve this aim. The primary purpose of this review is to summarize available literature for eHealth strategies that have been investigated in randomized controlled trials in post-myocardial infarction (MI) patients. The second purpose of this review is to investigate the clinical effectiveness in post-MI patients. Areas covered: The literature was searched using PubMed. Randomized controlled trials (RCTs) describing interventions in patients that had experienced an ST-elevation myocardial infarction or non-ST acute coronary syndrome were eligible for inclusion. Fifteen full-texts were included and their results are described in this review. These RCTs described interventions that used remote coaching or remote monitoring in post-MI patients. Most interventions resulted in an improved cardiovascular risk profile. Remote coaching had a positive effect on activity and dietary intake. Expert opinion: eHealth might be clinically beneficial in post-MI patients, particularly for risk estimation. Moreover, eHealth as a tool for remote coaching on activity is a good addition to traditional cardiac rehabilitation programs. Further research needs to corroborate these findings.

Impact of cardiac rehabilitation referral on one-year outcome after discharge of patients with acute myocardial infarction.

BACKGROUND: Cardiac rehabilitation after an acute myocardial infarction has a class I recommendation in the present guidelines. However, data about the impact on mortality in Switzerland are not available. Therefore, we analysed one-year outcome of acute myocardial infarction patients according to cardiac rehabilitation referral at discharge. DESIGN AND METHODS: Data were extracted from the Swiss AMIS Plus registry and included patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction, who were asked to give their informed consent to a telephone follow-up one year after discharge. RESULTS: From 10,141 patients, 1956 refused to participate in follow-up and 302 were lost to follow-up. There were 4508 (57.2%) patients with cardiac rehabilitation referrals compared with 3375 (42.8%) without. Patients referred to cardiac rehabilitation were younger (62.4 years vs. 68.8 years), more often male (77% vs. 70%), presented more often with ST-elevation myocardial infarction (63.5% vs. 52.1%) and, apart from smoking (44.0% vs. 34.9%), they had fewer risk factors, such as dyslipidaemia (55.0% vs. 60.1%), hypertension (55.6% vs. 65.3%) and diabetes (16.7% vs. 21.5%). Patients referred to cardiac rehabilitation had a lower crude one-year all-cause mortality (1.7% vs. 5.8%; p < 0.001) and lower rates of re-infarction, rehospitalization for cardiovascular disease and intervention (all p < 0.005). In a multivariable logistic regression analysis, cardiac rehabilitation was an independent predictor for lower mortality rate (odds ratio 0.65; 95% confidence interval 0.48-0.89; p = 0.007). CONCLUSIONS: Although the detailed data of cardiac rehabilitation programmes and patient participation were not available for this study, our data from 7883 acute myocardial infarction patients showed a better one-year outcome for patients with cardiac rehabilitation referrals than for those without.

Improvement of low-density lipoprotein cholesterol target achievement rates through cardiac rehabilitation for patients after ST elevation myocardial infarction or non-ST elevation myocardial infarction in Germany: Results of the PATIENT CARE registry.

AIMS: The PATIENT CARE registry aimed to document clinical characteristics of patients during cardiac rehabilitation after myocardial infarction, including the current pharmacological treatment, risk factor modification and achievement of treatment targets for low-density lipoprotein cholesterol (LDL-C). METHODS: Multicentre, prospective non-interventional study at 20 cardiac rehabilitation in-patient centres across Germany. RESULTS: A total of 1408 patients post myocardial infarction were analysed. Patients' mean age was 62 ± 11 years and 27.0% were women. ST elevation myocardial infarction ( n = 657; 48.7%), and non-ST elevation myocardial infarction ( n = 617; 45.8%) were equally balanced causes for hospitalization, while previous coronary artery bypass grafting was reported in n = 134 patients (9.9%). On average, cardiac rehabilitation began 19 ± 10 days after the index event and lasted for 22 ± 4 days. At discharge, 96.7% of patients received statins, 13.0% another lipid-lowering medication in addition to a statin, 98.5% antithrombotic drugs and 22.3% antidiabetic medication. The rate of patients with LDL-C on target according to the European Society of Cardiology/European Atherosclerosis Society dyslipidaemia guidelines 2011 (<70 mg/dl (1.8 mmol/l) or at least 50% reduction of baseline value) was increased from 21.4% at admission to cardiac rehabilitation to 41.9% at discharge after cardiac rehabilitation. Most patients (95.2%) completed the cardiac rehabilitation and 88% returned to their former work at full time. CONCLUSION: During cardiac rehabilitation, the modifiable cardiovascular risk factors, in particular the LDL-C, were substantially improved in patients after myocardial infarction. The great majority were able to return to work. However, less than 50% reached the LDL-C guideline targets during short-term cardiac rehabilitation.

Cardiac rehabilitation after STEMI.

Cardiac rehabilitation is the most important evidence-based intervention for secondary prevention after STEMI, nevertheless, only a minority of patients may access to a cardiac rehabilitation program. In this review the priority criteria for admission to cardiac rehabilitation and the main barriers that limit a larger involvement of the patients are discussed. Among the components of cardiac rehabilitation exercise is crucial and a tailored exercise training program and a tight monitoring of adherence to lifestyle recommendations are mandatory. Finally, the development of light cardiac rehabilitation pathways and home programs may allow a larger diffusion of outpatient programs. In conclusion, the participation to a cardiac rehabilitation program following STEMI is about 25-35% in western countries, and only 15% in Italy. Stressing the importance of cardiac rehabilitation participation is crucial for all post-myocardial infarction patients, particularly for the vulnerable socioeconomic populations.

Heart rate recovery improvement in patients following acute myocardial infarction: exercise training, ß-blocker therapy or both.

Heart rate recovery (HRR) is a strong mortality predictor. Exercise training (ET) and ß-blocker therapy have significant impact on the HRR of patients following myocardial infarction (MI). However, the combination of ET and ß-blocker therapy, as well as its effectiveness in patients with a more compromised HRR (≤12 bpm), has been under-studied. Male patients (n = 64) post-MI were divided: Training + ß-blocker (n = 19), Training (n = 15), ß-blocker (n = 11) and Control (n = 19). Participants performed an ergometric test before and after 3 months of intervention. HRR was obtained during 5 min of recovery and corrected by the cardiac reserve (HRRcorrCR ). Compared to pre-intervention, HRRcorrCR was significantly increased during the 1st and 2nd minutes of recovery in the Training + ß-blocker group (70·5% and 37·5%, respectively; P<0·05). A significant improvement, lasting from the 1st to the 4th minute of recovery, was also observed in the Training group (47%, 50%, 25% and 8·7%, respectively; P<0·05). In contrast, the ß-blocker group showed a reduction in HRRcorrCR during the 2nd and 3rd minutes of recovery (-21·2% and -16·3%, respectively; P<0·05). In addition, interventions involving ET (Training + ßb, Training) were significantly more effective in patients with a pre-intervention HRR ≤ 12 bpm than for patients with HRR > 12 bpm. Combination of ß-blocker therapy with ET does not compromise the effect of training and instead promotes HRR and aerobic capacity improvement. In addition, this combination is particularly beneficial for individuals presenting with a more compromised HRR. However, chronic administration of ß-blocker therapy alone did not promote improvement in HRR or aerobic capacity.

Social inequality and barriers to cardiac rehabilitation in the rehab-North register.

AIM: Barriers to participation in cardiac rehabilitation (CR) may occur at three levels of the referral process (lack of information, declining to participate, and referral to appropriate CR programme). The aim is to analyse the impact of socioeconomic status on barriers to CR and investigate whether such barriers influenced the choice of referral. METHODS: The Rehab-North Register, a cross-sectional study, enrolled 5455 patients hospitalised at Aalborg University Hospital with myocardial infarction (MI) during 2011-2014. Patients hospitalised with ST-elevated MI and complicated non-ST-elevated MI were to be sent to specialized CR, whereas patients with uncomplicated non-ST-elevated MI and unstable angina pectoris were to be sent to community-based CR. Detailed selected socioeconomic information was gathered from statistical registries in Statistics Denmark. Data was assessed using logistic regression. RESULTS: Patients being retired, low educated, and/or with an annual gross income <27.000 Euro/yr were significantly less informed about cardiac rehabilitation programmes. Patients being older than 70 years, retired, low educated and/or with an annual gross income <27.000 Euro were significantly less willing to participate in CR. Further, this patient population were to a higher extent referred to community-based CR. CONCLUSION: Patients with low socioeconomic status received less information about and were less willing to participate in cardiac rehabilitation. The same patient population was to a higher extent referred to community-based CR. Knowledge about barriers at different levels and the impact of social inequality may help in tailoring a better approach in the referral process to CR.

A brief period of intensive cardiac rehabilitation improves global longitudinal strain and diastolic function after a first uncomplicated myocardial infarction.

Objectives In patients with abnormal left ventricular ejection fraction (LVEF) after acute myocardial infarction (AMI), cardiac rehabilitation with physical training prevents cardiac remodelling. To define the role of rehabilitation in the recovery of ventricular function in less severe cases, we studied its effects on more refined indexes of left ventricular function in uncomplicated, low-risk patients. Methods and results Fifty-five patients underwent percutaneous coronary revascularization after uncomplicated first AMI. Thirty-four started cardiac rehabilitation with counselling and physical training; 21 patients did not train, followed a counselling program and were taken as controls. Echocardiography was performed at baseline, after rehabilitation or counselling program and at six months follow-up. We measured: global strain (GS%) with speckle tracking analysis, E/e' by tissue Doppler imaging (TDI), left ventricular elastance (KLV) from the deceleration time (DT), LVEF, systolic and diastolic volumes, wall motion score index (WMSI). At baseline, groups had similar GS%, KLV, LVEF, DT, E/e', systolic and diastolic volumes, WMSI. Rehabilitation increased peak VO2 by 18% (P < 0.05) and improved GS%, KLV, LVEF, E/e' and WMSI (P < 0.02) that were unchanged in controls. The improvement persisted at six months. Conclusions After a first uncomplicated AMI, abnormalities of left systolic and diastolic ventricular function may be present persisting over time despite a normal LVEF, which are fully reverted by cardiac rehabilitation.

Cardiac rehabilitation in patients with ST-segment elevation myocardial infarction: can its failure be predicted?

BACKGROUND: The prognosis in patients after acute coronary syndromes (ACS) is significantly burdened by coexisting anaemia, leukocytosis and low glomerular filtration rate (GFR). Hyperglycaemia in the early stages of ACS is a strong predictor of death and heart failure in non-diabetic subjects. This study aimed to evaluate the effect of hyperglycaemia, anaemia, leukocytosis, thrombocytopaenia and decreased GFR on the risk of the failure of cardiac rehabilitation (phase II at the hospital) in post-ST-segment elevation myocardial infarction (STEMI) patients. METHODS: The study included 136 post-STEMI patients, 96 men and 40 women, aged 60.1 ± 11.8 years, admitted for cardiac rehabilitation (phase II) to the Department of Internal Medicine and Cardiac Rehabilitation, WAM University Hospital in Lodz, Poland. On admission fasting blood cell count was performed and serum glucose and creatinine level was determined (GFR assessment). The following results were considered abnormal: glucose ⩾ 100 mg/dl, GFR < 60 ml/min/1, 73 m², red blood cells (RBCs) < 4 × 106/µl, white blood cells (WBCs) > 10 × 103/µl; platelets (PLTs) < 150 × 10³/ml. In all patients an exercise test was performed twice, before and after the completion of the second stage of rehabilitation, to assess its effects. RESULTS: Based on logistic regression analysis and the results of an individual odds ratio (OR) of the tested parameters, their prognostic impact was determined on the risk of failure of cardiac rehabilitation. This risk has been defined on the basis of the patient's inability to tolerate workload increment >5 Watt in spite of the applied program of cardiac rehabilitation. As a result of building a logistic regression model, the most statistically significant risk factors were selected, on the basis of which cardiac rehabilitation failure index was determined. leukocytosis and reduced GFR determined most significantly the risk of failure of cardiac rehabilitation (respectively OR = 6.42 and OR = 3.29, p = 0.007). These parameters were subsequently utilized to construct a rehabilitation failure index. CONCLUSIONS: Peripheral blood cell count and GFR are important in assessing the prognosis of cardiac rehabilitation effects. leukocytosis and decreased GFR determine to the highest degree the risk of cardiac rehabilitation failure. Cardiac rehabilitation failure index may be useful in classifying patients into an appropriate model of rehabilitation. These findings support our earlier reports.

Depressive symptoms, functional measures and long-term outcomes of high-risk ST-elevated myocardial infarction patients treated by primary angioplasty.

The presence of major depressive symptoms is usually considered a negative long-term prognostic factor after an acute myocardial infarction (AMI); however, most of the supporting research was conducted before the era of immediate reperfusion by percutaneous coronary intervention. The aims of this study are to evaluate if depression still retains long-term prognostic significance in our era of immediate coronary reperfusion, and to study possible correlations with clinical parameters of physical performance. In 184 patients with recent ST-elevated AMI (STEMI), treated by immediate reperfusion, moderate or severe depressive symptoms (evaluated by Beck Depression Inventory version I) were present in 10 % of cases. Physical performance was evaluated by two 6-min walk tests and by a symptom-limited cardiopulmonary exercise test: somatic/affective (but not cognitive/affective) symptoms of depression and perceived quality of life (evaluated by the EuroQoL questionnaire) are worse in patients with lower levels of physical performance. Follow-up was performed after a median of 29 months by means of telephone interviews; 32 major adverse cardiovascular events (MACE) occurred. The presence of three vessels disease and low left ventricle ejection fraction are correlated with a greater incidence of MACE; only somatic/affective (but not cognitive/affective) symptoms of depression correlate with long-term outcomes. In patients with recent STEMI treated by immediate reperfusion, somatic/affective but not cognitive/affective symptoms of depression show prognostic value on long-term MACE. Depression symptoms are not predictors "per se" of adverse prognosis, but seem to express an underlying worse cardiac efficiency, clinically reflected by poorer physical performance.
