INTRODUCTION An international registry of ambulatory patients with stable coronary artery disease (CLARIFY) allows a comparison of management and outcomes in real‑life setting. OBJECTIVES We aimed to compare the management strategies and 5‑year outcomes in patients from Poland and from other European countries. PATIENTS AND METHODS Stable coronary artery disease was defined as previous myocardial infarction (MI) or revascularization, coronary stenosis greater than 50%, or documented symptomatic myocardial ischemia. Patients were followed on an annual basis for 5 years. RESULTS Among the total of 32 703 patients, 1000 were enrolled in Poland, and 17 326 in other European countries. Polish patients were younger, with a higher proportion of women, smokers, and patients with previous MI, dyslipidemia, and hypertension. Patients in both cohorts received adequate medical treatment, with more Polish patients receiving β‑blockers. Blood pressure and lipid control to target was similar and remained low in both cohorts. Diabetes control and successful smoking cessation rates were lower in Poland than in other European countries. Polish patients more often underwent percutaneous coronary intervention. All‑cause (8.5% vs 7.9%; P = 0.81) and cardiovascular death rates (5.3% vs 4.9%; P = 0.82) did not differ between the groups, but fatal or nonfatal MI occurred more often in the Polish cohort (5% vs 3.1%; P = 0.006). Angina control was better in Poland than in other European countries (Canadian Cardiovascular Society class II-IV, 11.5% vs 15.8% of patients; P <0.001). CONCLUSIONS Risk factor control was insufficient both in patients from Poland and in those from other European countries. The more frequent use of revascularization in Polish patients was not linked to improved outcomes, but, together with more extensive prescription of β‑blockers, might have contributed to better angina control.

INTRODUCTION Despite the progress in cardiology in recent years, cardiovascular (CV) diseases remain the main cause of death in European countries. The knowledge concerning the structure of hospital admissions for CV diseases and clinical outcomes is fragmentary. OBJECTIVES The aim of the study was to analyze the characteristics and outcome of patients with CV disease, hospitalized between 2006 and 2014 and included in the Silesian Cardiovascular Database (SILCARD) covering a population of 4.6 million patients. PATIENTS AND METHODS SILCARD is based on the data from the Regional Department of the National Health Fund in Poland. The enrollment criteria were any hospitalization at a department of cardiology, cardiac surgery, diabetology or vascular surgery and hospitalization with a cardiovascular diagnosis at a department of internal medicine or intensive care. The data come from 310 hospital departments and 1863 outpatient clinics, and contain information on 487 518 patients and 956 634 hospitalizations. RESULTS Heart failure (20%) and stable coronary artery disease (18.5%) were the most frequent primary causes of hospitalization. The number of hospitalizations due to heart failure, aortic stenosis, and pulmonary embolism significantly increased. The highest 12‑month mortality was reported in patients with heart failure and pulmonary embolism (>30%). A decrease in 12‑month mortality in patients with heart failure, stable coronary artery disease, myocardial infarction, and atrial fibrillation was noted, although for some disease entities, it remained relatively high. CONCLUSIONS Between the years 2006 and 2014, in‑hospital and 12‑month mortality showed a trend for decline in many disease entities, with considerable space for prognostic improvement.

Introduction: The use of classic risk scores in patients with type 2 diabetes have numerous limitations. Relationships between coronary artery calcium score (CACS) and traditional risk factors are derived from statistical analyses. At present, there are no data on the evaluation of the CACS on 64‑slice multi-detector computed tomography in patients with type 2 diabetes and ischemic symptoms based on a head‑to‑head comparison with matched nondiabetics., Objectives: We aimed to examine the associations between traditional risk factors and the CACS in a nested case‑control study., Patients and Methods: We performed a retrospective analysis of data from 2482 consecutive symptomatic subjects with known CACS. We identified 325 patients with type 2 diabetes. From the remaining subjects, 325 controls matched for age, sex, and risk factors were selected., Results:  Higher CACS values were observed in patients with diabetes (median, 50 Agatston units [AU]; range, 0-4330) compared with nondiabetic controls (9 AU, 0-3036, P <0.001). Positive CACS values were more common in diabetic patients (73.5%) compared with nondiabetic controls (60.9%, P <0.001). The highest CACS value was observed in men (95.5 AU, 0-3755). The median CACS value in nondiabetic men was comparable to those in diabetic women (24.5 AU, 0-3036 vs. 24.5 AU, 0-3755). The lowest CACS values were observed in control women (3 AU, 0-2144). Coronary artery calcium was more diffused in diabetic patients compared with controls (P <0.01). A multivariate analysis showed that older age and male sex were independent predictors of the CACS. Traditional risk factors accounted only for 10% of interindividual variance in the presence of calcified atherosclerotic plaques., Conclusions: Coronary calcified lesions are more frequent in symptomatic patients with type 2 diabetes compared with matched nondiabetic subjects. Our results seem to provide evidence that traditional risk factors do not explain more common, diffuse, and extensive calcified lesions in diabetic subjects.

In 1997 the Southern Poland Epidemiological Survey trial was conducted, the largest primary prevention action in Poland, which comprised 50,111 subjects. In this trial subjects with total cholesterol over 300 mg% were identified. After two years period these subjects were contacted to assess the kind and effectiveness of their action to reduce hypercholesterolemia and other CAD risk factors. The role of general practitioner was also addressed. The aim of the present study was to assess the influence of primary prevention on the following parameters: intensity and frequency of risk factors occurrence, rate of individual risk of coronary heart disease in the study group and the assessment of influence of primary care physician action on risk factors reduction in the study population. 1090 persons were invited into the study. 293 (27%) of them came to the hospital for further investigation. After exclusion of patients in whom CAD was already present in 1997, a group of 263 patients was analyzed. The study group was divided in three parts: non-compliant to the primary prophylaxis recommend alians (52 pers.), performing the primary prophylaxis recommendations on their own (113 pers.), and performing the recommendations under supervision of the general practitioner (89 pers.). Blood pressure, smoking, weight reduction, physical activity improvement and lowering of the total cholesterol were analyzed. The risk of CAD in 1997 in 1999 was evaluated according to the risk score. In the group following the recommendations unders medical supervision significant CAD risk reduction, lowest CAD risk in 1999, highest ratio of smoking quitting, tendency to physical activity improvement, highest weight reduction (especially in people with visceral obesity), and the lowering of total cholesterol level were observed. In the group following the recommendations without medical supervision significant level of smoking quitting and weight reduction were observed. In this group total cholesterol level and CAD risk were unchanged. On the basis of these results following conclusions were formed: 1) Prevention action caused smoking quitting, body mass reduction, total cholesterol reduction and tendency to improved physical activity. 2) Prevention action caused only minor personal CAD risk reduction. 3) General practitioner activity lowered CAD incidence risk. 4) Education of people at risk, general practitioners and the entire population on avoiding coronary artery disease is necessary.

Unlabelled: The recurrent stenosis of previously successfully dilated coronary arteries still remains a matter of concern despite of the improved short and long term results of percutaneous coronary angioplasty. The role of dyslipidaemia in the origin of restenosis after coronary angioplasty is still controversial. The aim of our study was to evaluate the efficacy of hypolipemic treatment in patients undergoing coronary angioplasty and to find out whether successful lowering of lipid parameters to normal limits is related to improvement exercise capacity and systolic function of left ventricle. The study group comprised 152 patients (17 women, 135 men), aged 52 +/- 8.8 years, who were reffered for percutaneous coronary angioplasty (PTCA). The patients were divided, according to the ratio of total cholesterol to HDL cholesterol (CH/ch-HDL), into two subgroups: subgroup I with CH/ch-HDL > 5.0 and subgroup II with CH/ch-HDL < or = 5.0. In all patients following parameters: total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides and body mass index were measured before PTCA, 1 month and 6 months after the procedure. At the same times a treadmill test and echocardiography were performed. Baseline total cholesterol, HDL cholesterol and triglycerides were significantly higher in subgroup I. In subgroup I Ch/ch-HDL ratio was at baseline 7.4 +/- 2.0 and decreased 6 months after PTCA to 5.2 +/- 1.7, p < 0.001. The CH/ch-HDL ratio was 4.2 +/- 0.6 in subgroup II before PTCA and remained the same 4.1 +/- 1.2 after 6 months. Before PTCA, the exercise capacity did not differ between groups 9.1 +/- 2.5 vs 9.6 +/- 3.3 MET, p = ns. A significant improvement of exercise capacity was observed in subgroup I 1 month after PTCA 9.1 +/- 2.5 to 11.2 +/- 2.7 MET, p < 0.001, remaining at the same level after 6 months. The differences seen in group II did not reach the statistical significance. Echocardiography revealed improvement of left ventricle contractility in both subgroups, with statistically significant increase in group I (1.24 +/- 0.36 to 1.14 +/- 0.27, p < 0.001). The left ventricle systolic function was within normal limits in all patients before coronary angioplasty and increased significantly 1 month after PTCA in subgroup I (56.1 to 60.4%, p < 0.001). 6 months after PTCA no further significant changes were observed., Conclusions: The dyslipidaemic state recognised before PTCA does not influence clinical outcomes after the procedure. Lipid lowering therapy should be offered to every patient undergoing coronary angioplasty regardless of the baseline value of total cholesterol to HDL cholesterol ratio. Optimal treatment of dyslipidaemia leading to lower total cholesterol, triglycerides and total cholesterol to HDL cholesterol ratio, to normal limits, is associated with improved exercise capacity and systolic function of left ventricle six months after successful coronary angioplasty.

The aim of this study was to assess the effect of chronic home oxygen therapy on cardiac function in patients with idiopathic interstitial lung fibrosis. Ten patients (Group A) received standard pharmacological treatment (prednisone 10-15 mg/day) and supplementary home oxygen therapy (mean 16.4 h/day) for the period of 4 years. Eight patients (Group B) received pharmacological treatment alone for the same period of time. Left ventricular ejection fraction was measured with a scintillation probe. Right and left ventricular function was also assessed by means of echocardiography. All measurements were taken at the beginning of study and repeated at the end of the 4 year follow-up. Anatomical and functional deterioration was slower in group A than in group B. Statistically significant differences between the groups at follow-up were found with respect to the right ventricle-early inflow velocity and tricuspid E/A ratio. Changes in left ventricular function were also different between the groups. A significant decrease in ejection fraction and mitral E/A ratio was observed in group B, while the corresponding changes in group A were not significant. These results suggest that chronic home oxygen therapy attenuates cardiac dysfunction in patients with idiopathic interstitial lung fibrosis.

The study was performed in 18 patients (15 F and 3-M) aged 35-57 yers (mean 46 +/- 7) diagnosed as idiopathic lung fibrosis. Ten patients (group A) recived standard treatment (prednisone 10-15 mg/day) and supplementary home oxygen therapy (mean 16.4 h/day) for a period of 4 years. During exacerbations antibiotics, theophylline and expectorants were prescribed. Eight patients (group B) receiving the same treatment without home oxygen, served as controls. At study entry lung function test (TLC, VL, Dlco), blood gases, hematocrit, hemodynamic parameters of the pulmonary circulation and thermodilution cardiac output were measured in all patients. The measurements were repeated after 4 years of follow-up. At follow-up examination no differences in pulmonary function parameters were shown between the groups. Mean pulmonary artery pressure and pulmonary vascular resistance were significantly lower in patients receiving home oxygen therapy (group A) as compared with those treated pharmacologically only (group B). Best effects of oxygen therapy were observed in patient with lower pulmonary artery pressures at study entry.

Immediate effect of PTCA and CABG for unstable angina then followed-up for PTCA and CABG several years are analyzed in 112 patients selected out of 204 unstable angina patients hospitalized from 1990 to 1991. Fifty three patients, aged 25-68 (mean 51) were assigned to PTCA, fifty nine aged 33-69 (mean 53) were subjected to CABG. Both groups comprised of 72% and 83% males respectively. Nine patients with de novo angina, forty with crescendo angina and four with prolonged stenocardia were assigned to PTCA. 28% of patients have had myocardial infarction. Nine patients with de novo angina and fifty with crescendo angina were assigned to CABG. 56% of them have had myocardial infarction. Left ventricular ejection fraction (LVEF) less than 40% was found in 8 (15%) PTCA patients and in 18 (31%) patients who underwent CABG. Full revascularization was achieved in 38 (73%) patients treated with PTCA and 46 (78%) CABG patients. In 9/17% patients only critical stenosis in multivessel disease was subjected to PTCA. Four cases of myocardial infarction underwent intervention and all of these patients died: one (2%) after PTCA, and three (5%) after CABG. Fifty two patients after PTCA and fifty six after CABG were followed for one to four (mean 3) years. Thirty one percent of patients after PTCA and 41% after CABG were asymptomatic, 61% and 54% respectively had little to moderate symptoms. Left ventricular systolic function improved in most patients, predominantly in those with LVEF less than 40% (p < 0.05) treated with PTCA. Hospitalization due to anginal pain was needed in 46% of patients after PTCA and 15% after CABG (p < 0.05). Coronary artery restenosis after PTCA was successfully treated with re-PTCA or CABG in 9 (17%) patients. Venous graft stenoses were dilated in two cases. Myocardial infarction occurred in 3 (6%) patients after PTCA and 2 (4%) patients after CABG. One patient died after redilatation CABG treated patients required nonsignificantly less antianginal drugs. Four week survival rate in PTCA group and CABG group was 98% and 95% respectively; three year survival was 95% in both groups. We conclude, that unstable angina patients requiring either angioplasty or surgery may expect good procedural and long term prognosis. Remarkably good results may be expected in successfully revascularised patients with low ejection fraction.

Percutaneous transluminal coronary angioplasty was employed in a group of 178 patients (151 males and 27 females) aged 24 to 68 years (mean 42 +/- 12 years). Stable angina was diagnosed in 136 patients, unstable angina in 38, and an acute infarct in 4. In 150 patients there was one, in 25 two and in 5 patients 3 target stenoses. Lesions were localised in the left anterior descending artery in 130 cases, in the circumflex artery in 32 cases and in the right coronary artery in 49 cases. The attempts to dilate 78 stenoses with a fixed-wire, non-guided system was successful in 78% of cases. Success rate with the over-the-wire system was 85%. In total, we successfully dilated 173 patients, i.e. 82%. The highest success rate, 85%, was achieved in lesions localized in the left anterior descending artery and lowest in lesions localized in the left circumflex artery. Success rate in the groups with stable and unstable coronary artery disease was similar. Complications occurred in 6% of the cases. Experience of the operators involved in PTCA is an important factor influencing the success rate. In the first year of using this technique, good results were achieved in 48% of patients, in the second year in 63%. During the next two years 86% of the stenoses were successfully dilated.
