Fifty-two cases of acute phase subarachnoid hemorrhage were studied by brain CT scanning to determine the presence and incidence of ischemic myocardial disorder, the relationship between ischemic change and severity, disease prognosis, and the relationship between acute phase circulatory dynamics and so-called neurogenic pulmonary edema. In all cases, ECGs were carried out and CPK-MB determined. Some of the patients underwent Tl myocardial scintigraphy, echocardiography, cardiac catheterization, as well as circulatory dynamic investigation (by Swan-Ganz catheter) and arterial blood gas analysis. In 31 of the 52 cases (59.6%), 3-day ECG series revealed ischemic changes. These findings were backed up by other cardiac function tests, thus suggesting that myocardial ischemia was present. Results in cases undergoing cardiac catheterization revealed that the myocardial ischemic changes were not due to organic constriction of the coronary artery. Included in those cases in which ECG markedly changed and CPK-MB rose substantially were many patients for whom the prognosis was poor. Evaluation of respiratory function and circulatory dynamics in cases of so-called neurogenic pulmonary edema seemed to indicate decline in cardiac function owing to myocardial ischemic change. This could account for onset of symptoms. These findings support the need for adequate circulatory management in cases of acute subarachnoid hemorrhage with pulmonary edema and/or changes on ECG. In such cases, concurrent catheterization and cerebral angiography (cerebro-cardiac catheterization: CCC) proved effective for evaluating cardiac function and determining whether heart disease was also present.

The "papillary muscle dysfunction" concept includes a disrupted sequence of one or more structures of the mitral valve complex and not merely a disturbance of a papillary muscle itself. We studied a group of seventeen patients, 14 men and 3 women (mean age 51 and 39 years, respectively). Acute myocardial infarction was the first evidence of heart disease. In all of them, Doppler and M mode echocardiography were performed and correlation clinical features were done. In addition a tricuspid regurgitation flow patterns was scanned on each patient. Mitral regurgitation was found in 29% of them by Doppler echocardiography and only 17% had a mitral systolic murmur suggestive of this entity. In those patients with mitral regurgitation-flow patterns, the infarct site was similar to those with anterior and inferior infarction and serum CPK-level was greater in these patients than the non-mitral regurgitation flow pattern group. The evidence of tricuspid regurgitation by pulsed-Doppler echocardiography was associated with mitral regurgitation in 80% of patients, mainly those with right ventricular extension of acute myocardial infarction, and with the greatest hemodynamic impairment. It seems likely in this study, that mitral regurgitation was due to valve ring dilation with an increase of left ventricular diameter and a decrease on ventricular systolic function.

The serum GOT, CPK, LDH of 18 patients with heart disease were determined at pre- and postoperative periods. At postoperative period all the three serum enzymes were increased apparently (P less than 0.001). Slight to moderate myocardial ultrastructural damages were observed postoperatively in 10 cases. The degree of myocardial injure was correlated with the rising levels of the serum enzymes. This suggested that the change of the three enzymes may be utilized as a reference index of degree of myocardial injure.

Toxic manifestations of digitalis are one of the most prevalent adverse drug reactions encountered in clinical practice. The estimated incidence is about 20% in hospitalized patients in the USA. The authors describe a rare case of myocardial "catecholamine necrosis" (anteroseptal myocardial infarction) during accidental digitalis intoxication. A male patient, 75 years old, suffering from cirrhosis and ascites, take on by mistake a tablet of digoxin 0.25 mg. four times at day for eleven days. He hadn't heart disease in the past. At the eleventh day the patient showed a deep tiredness and so he was submitted to a clinical examination and electrocardiogram. The ECG demonstrated an anteroseptal myocardial infarction in the second-third electrical stage. The patient was hospitalized. The successive examination revealed: very high plasma digitalis concentrations; an increase of the serum levels of CPK and LDH; a significant increase of plasmatic and urinary catecholamine levels which return to normal values after fifteen days; apical akinesia at the echocardiographic examination; no signs of residual myocardial ischemia to the echo-dypiridamole stress test; normal coronary artery to the coronary arteriography and absence of coronary artery spasm to the ergonovine test. Furthermore the abdominal echography and the abdominal computerized tomography didn't reveal surrenal disease but showed an important liver disease. The patient was free from other cardiac events in the follow-up. Generally, during the digitalis intoxication we observe various rhythm and conduction disturbances. Instead in this case no serious arrhythmias were registered and the main expression of the drug toxicity was an anteroseptal myocardial infarction with undamaged coronary artery. Also the usual extracardiac symptoms and signs of the digitalis intoxication were absent in this case. All these observations can be explained with the pathological increase of the cathecholamine levels, indirectly induced by digitalis; with the direct toxic effect of the drug at the myocardic level; with the contemporary absence of ionic disturbances; with the concomitant liver disease. The direct toxic effect of the digitalis produced an increase in calcium ions availability for the electromechanical coupling and an increase of the intramyocardial pressure; the increase of the adrenergic activity determined contemporary an increase in the oxygen consumption of the myocardial cells, a rise of vascular tone and coronary artery tone and a reduction of the duration of the diastole. All these factors provoked a "primary and secondary" ischemia which evolved toward a real "cathecholamine necrosis" and produced a myocardial infarction. This hypothesis explains the myocardial infarction in absence of injury at the coronary arteriography and without coronary spasm at the ergonovine test; moreover it explains the transient increase in cathecholamine plasma levels observed in the acute phases an normalized after fifteen days. The "cathecholamine necrosis" is an anatomical definition, nevertheless in our opinion it gives account of the rare clinical situation observed.

The beneficial effects of a stable prostacyclin analogue (PGI2-A), OP 41483 against myocardial ischemic injury were experimentally and clinically evaluated. In 31P-NMR study, the preischemic treatment with PGI2-A prevented myocardial ATP depletion of rat hearts which were subjected to 20 min global ischemia. In patients with congenital heart disease, the PGI2-A of 300 ng/ml was added to the glucose-insulin-potassium cardioplegia (PGI2-group), and this group was compared to control group without PGI2-A in terms of postoperative maximal leakage of CPK-MB (maxCPK-MB). In patients under 1 yr or patients over 1 yr with aortic cross clamp time exceeded 120 min, the maxCPK-MB was significantly (p < 0.05) reduced as compared to the control. This stable PGI2 analogue has shown significant myocardial protective effects experimentally and also in clinical setting.

Heart failure is not a common manifestation of hypothyroidism if there is no underlying heart disease. We report a case of familial primary hypothyroidism in a young male, that clinically onset with dyspnea, hemoptysis and serum CPK elevation, and in which further explorations revealed a dilated cardiomyopathy due to hypothyroidism. Because of its bad prognosis, we underline the need to identify those cases of dilated cardiomyopathy that can be treated with the appropriate therapy.

Bretschneider cardioplegic solution is used widely in Europe. The aim of this study is to investigate the efficacy of Bretschneider cardioplegic solution for open heart surgery of congenital heart disease in comparison with blood cardioplegia. From June 1995 to July 1997, we treated 32 congenital heart disease patients using Bretschneider cardioplegic solution and 20 patients using blood cardioplegia. Hospital mortality, water balance during operation, percentage of arrhythmia, and intubation time were not significant in both group. Also CPK and CPK-MB were not significant in both group. Bretschneider cardioplegic solution had preserved the heart as same as blood cardioplegia. This is a very convenient method so that we can use only one time infusion.

Studies on the lipid peroxidation and antioxidant changes and their significance during myocardial injury have provided a new insight into the pathogenesis of heart disease. The heart failure subsequent to myocardial infarction may be associated with an antioxidant deficit as well as increased myocardial oxidative stress. The present study was designed to evaluate the effect of the combination of ferulic acid and ascorbic acid on antioxidant defense system and lipid peroxidation against isoproterenol (ISO)-induced myocardial infarction in rats. Induction of rats with isoproterenol (150 mg/kg body weight daily, i.p.) for 2 days resulted in a marked elevation in lipid peroxidation, serum marker enzymes (LDH, CPK, GOT, and GPT), and a significant decrease in activities of endogenous antioxidants (SOD, GPx, GST, CAT, and GSH). Pre-co-treatment with the combination of ferulic acid (20 mg/kg body weight/day) and ascorbic acid (80 mg/kg body weight/day) orally for 6 days, significantly attenuated these changes when compared to the individual treatment groups. Histopathological observations were also in correlation with the biochemical parameters. Thus, ferulic acid and ascorbic acid significantly counteracted the pronounced oxidative stress effect of ISO by the inhibition of lipid peroxidation, restoration of antioxidant status, and myocardial marker enzymes levels. In conclusion, these findings indicate the synergistic protective effect of ferulic acid and ascorbic acid on lipid peroxidation and antioxidant defense system during ISO-induced myocardial infarction and associated oxidative stress in rats.

The article presents the results of studies of 104 patients with cardiomyopathy hospitalized in the cardiorheumatological departments of the Republican Specialized Scientific and Practical Medical Center of Pediatrics in Tashkent and the Republican Children's Multidisciplinary Medical Center of the Republic of Karakalpakstan. An analysis of the results of the study showed that in children with cardiomyopathy there is an increase in the level of tissue (LDH, CPK) and cardiospecific (CPK-MB) enzymes, regardless of the region of residence and the form of the disease, which indicate myocardial dysfunction. Therefore, these enzymes can be regarded as highly specific biochemical markers of myocardial damage, and an increase in their activity can be used as criteria for the diagnosis of heart disease. Of the biochemical parameters, a reliable prognostic criterion for the development and outcome of cardiomyopathy is a progressive increase in the level of endothelin with increasing duration of the disease.

Patients on chronic dialysis have an increased risk for SARS CoV-2 virus disease and its complications because of multiple comorbidities and alterations in the immune response caused by renal disease. In this retrospective observational study we describe the clinical features and the evolution of SARS CoV-2-related disease in 19 patients of our Pesaro and Fano facilities, where incidence and mortality of the epidemic were among the highest in Italy. A total of 176 patients were undergoing chronic treatment, 153 hemodialysis and 23 peritoneal dialysis. The incidence of infection was 10,8%, with 84% needing hospitalization and mortality amounting to 53%. The most frequent onset symptom was fever (84,2%) and the most used therapy was an association of low molecular weight heparin and hydroxychloroquine (57,9%). Comparing the deceased and survivor populations we noticed significant differences in age and presence of cardiopathy for what concerns anamnestic data and in fatigue and dyspnea in terms of clinical presentation. LDH and CPK resulted highest among deceased patients, while the use of enoxaparin was more frequent in survivors. By observing contagions over time, we also noticed that most of the cases, and the ones with worse clinical condition and outcome, all occurred in the early stage of the epidemic and in particular within the first 20 days from the implementation and codification of the measures to prevent its spread, the only modifiable factor that had an unmistakable effect on the evolution of events.
