Subacute stent thrombosis following coronary angioplasty: incidence and risk factors.

Background: Subacute stent thrombosis was a significant complication in the early years of coronary stenting, often leading to myocardial infarction, need for urgent surgery or even death. The introduction of intracoronary ultrasound enabled the identification and proper treatment of the main causes of stent thrombosis, reducing the rate of this complication to 1%.

Aim: To identify risk factors of subacute stent thrombosis.

[Ear lobe crease as a factor of potential risk for coronary artery disease?--World news review and own research].

The aim of this study was to define the value of ear-lobe crease as the marker of potential risk of coronary artery disease on the basis of world's reports and own research. The test group consisted of 92 patients who were classified to coronary-artery bypass graft using coronarography. Patients were divided into 3 groups (A-without ELC, B-ELC on one ear, C-ELC bilateral).

[The level of erythropoietin in serum of patients with anemia during infective endocarditis].

The infective endocarditis is a septic syndrome caused by an infection in endocardium or in heart valves. The majority of patients with infective endocarditis develop normocytic anemia. The metabolic studies in septic shock syndromes documented an intensive proteolysis of muscles, visceral organs and blood proteins, and probably of erythropoietin as a glycoprotein as well.

[Survival of women and men after myocardial infarction does not differ. Results of several years' observation].

The contention that female gender is an independent factor that affects survival after acute myocardial infarction (AMI) is still controversial. The aim of this retrospective study was to assess whether or not early and late mortality after AMI is greater in women than in men. Data of 464 consecutive patients (130 women and 334 men) who had a documented acute myocardial infarction in our Department of Cardiology between 1990 and 1993 were eligible for the study.

[Evaluation of arterial blood pressure and heart rate during exercise tests in patients with essential hypertension in different stages of hypertension].

This article analyses the changes of arterial blood pressure and heart rate (HR) in 120 patients with essential hypertension during two successive exercise tests. Before and during the tests, the patients did not take any hypertensive drugs. The obtained measuring results at exercise tests and restitution were the basis for the calculating regression equations.

Results of long-term medical treatment of patients with arterial hypertension complicated by aortic dissection.

Unlabelled: The purpose of the study was to analyse results of ambulatory treatment of patients with arterial hypertension complicated by aortic dissection. Twenty patients (19 men, one woman), aged between 39 and 72 years, underwent full physical examination. In all cases the diagnosis of aortic dissection was confirmed by at least two different imaging methods (ultrasonography, digital subtractional angiography, computer tomography or nuclear magnetic resonance).

Hypertrophy or hyperplasia in cardiac muscle. Post-mortem human morphometric study.

In 103 hearts with various forms of cardiac muscle hypertrophy the following parameters were estimated: diameter, length, volume, density and number of myocytes, and density of myocyte nuclei. The values of all histometric parameters correlated well with left ventricular (LV) weight up to 350 g. In heavier hearts these parameters remained approximately of the same magnitude.

[Circadian changes in levels of magnesium in serum of healthy individuals].

Circadian changes in blood serum magnesium levels in healthy individuals. We examined circadian changes of the serum magnesium in 20 healthy subjects. Blood samples were taken every second hour during the 24 hours.

[Confirmed and borderline hypertension found in 44% of men (aged 40-59 years) working at the H. Cegielski plant in Poznań].

Blood pressure was measured in 3317 men, aged 40-59, working in H. Cegielski Metal Works in Poznań. The average systolic pressure for the whole population was 130.

[Hypertrophy or hyperplasia of myocytes in heart hypertrophy?].

One of the most controversial problem in cardiac muscle pathology is the existence of myocyte hyperplasia. The term hypertrophy indicates an increase in size of the individual muscle cells without changing their total number, whereas in hyperplasia there occurs proliferation of the myocyte. This fundamental question of the character of cardiac growth remains unresolved in spite of the wide attention it has received.

[Selected hemodynamic parameters in overweight patients with mild and moderate hypertension treated with low caloric diet].

Basic haemodynamic parameters - blood volume (BV), cardiac output (CO), stroke volume (SV), and total peripheral resistance (TPR) were studied in two groups of overweight patients with mild and moderate hypertension. Each group consisted of 15 subjects. The patients of the first group were kept on low caloric diet (1000-1100 cal per day).

[Comparison of the diagnostic value of echocardiographic, ecg and enzymatic investigations in acute myocardial infarction].

Two dimensional echocardiography (ECHO 2D) was performed in 133 patients 1-2, 3-5, 7-10, 21-28 days and 3, 6, 9, 12, 18 and 24 months after myocardial infarction. Standard ecg examination was carried out at the admission time, every 15 minutes during the first 2 hours, 3, 6, 12, 24 and 48 hours later, and afterwards in the same time as ECHO 2D. At the admission time and 4, 8, 12, 16, 20, 24, 36, 48, 60, and 72 hours later creatine kinase activity was determined.

[Value of exertional echocardiography and performance of transesophageal left atrial pacing done 3-4 weeks after acute myocardial infarction].

Two-dimensional echocardiography during exercise (ECHO W) and left atrial pacing (ECHO S) was done in 30 patients 3-4 weeks after acute myocardial infarction. Sensitivity of these methods to detect fresh myocardial ischemia was compared. Their prognostic value during 2 years after myocardial infarction was determined too.

[Dynamics of disorders of ventricular contraction studied by two-dimensional echocardiography 2 years after myocardial infarction].

Two-dimensional echocardiography (ECHO 2D) was performed in 133 patients 1-2, 3-5, 7-10, 21-28 days and 3, 6, 9, 12, 18 and 24 months after myocardial infarction. During 2-years observation after myocardial infarction a gradually diminishing occurrence of left ventricular (LV) systolic wall motion abnormalities, is seen mostly--akinesia. Dyskinesia is the most persistent form of asynergy appearing with similar frequency during the whole study period.

Relations between ECHO parameters, clinical course and prognosis.

[The effect of intravenous streptokinase on selected echocardiographic and clinical parameters of patients followed up for 2 years after myocardial infarction].

54 patients (pts) aged 70 years or younger with acute transmural myocardial infarction and onset of chest pain less than 12 hours were assigned in a blind manner to streptokinase group (SK), 54--to control group, 34 pts received intravenous infusion of 1,500,000 IU of SK/hour, 14 pts--2,000,000 IU/hour, and 6 pts--3,000,000 IU/2.5 hours. Intravenous streptokinase reduced left ventricular (LV) asynergy during hospital phase, decreased LV thrombus formation, and limited myocardial necrosis size 2 years after myocardial infarction.

[Coronary lumen diameter and cardiac mass in various forms of cardiac hypertrophy].

Morphometric evaluation of the epicardial arteries is described in detail in 103 patients with various forms of cardiac hypertrophy. Coronary lumen diameter increases with aging regardless of the cardiac mass. Such an increase is observed in some particular types of cardiac hypertrophy and presumably is caused by the changes of intramuscular vessels and diminished perfusion.

The values of all histometric parameters correlated well with the LV weight up to 350 g. In heavier hearts these parameters were approximately at the same magnitude.

One of most controversial problems in cardiac muscle pathology is the existence of myocyte hyperplasia. The term hypertrophy indicates an increase in size of the individual muscle cells without changing their total number, whereas in hyperplasia proliferation of the myocyte occurs.

Age of the patients ranged from 35 to 82, mean 60 years.
