In order to investigate the effect of a supplementation of vitamin D in the prophylaxis of fractures of the bones of aged people, an annual intramuscular injection of ergocalciferol (150,000-300,000 IU) was given to two series of aged subjects: first to 199 (45 male) of 479 subjects (110 male) aged more than 85 years who were living in their own home, and second to 142 (29 male) of 320 (58 male) subjects aged 75-84 and living in a home for aged people. This prospective series was divided into treatment groups according to month of birth. These injections were given annually from September to December in the years 1985-1989, two to five times to each participant. The fracture rates, laboratory values, vitamin D levels, possible side effects, and mortality were followed until October 1990. A total of 56 fractures occurred in the 341 vitamin D recipients (16.4%) and 100 in 458 controls (21.8%) (P = 0.034). The fracture rate was about the same in both outpatient and municipal home series. Fractures of the upper limb were fewer in the vitamin D recipients, 10/341 = 2.9% (P = 0.025), than in the controls, 28/458 = 6.1%, during the follow-up. A similar result was obtained in fractures of ribs, 3/341 = 0.9% and 12/458 = 2.6%, respectively. Fractures of the lower limbs occurred almost as frequently, 31/341 = 9.1%, among the vitamin D recipients as among the controls, 49/458 = 10.7%. The fracture rate was higher in females (22.2%) than in males (9.5%). The fractures were fewer in the vitamin D recipients only in females.(ABSTRACT TRUNCATED AT 250 WORDS) [ABSTRACT FROM AUTHOR]

The relationship of thyroid autoantibodies and elevated TSH level to indices of cardiovascular diseases was studied in two population series monitored for 5 years and in a cross-sectional hospital series. In a cohort of 1105 males, initially 55-74 years of age, deaths due to cardiovascular causes occurred in 19% of subjects with thyroid autoantibodies and in 11% of controls matched for age (P<0-05). In another cohort of 1045 males and 1223 females, initially 40-64 years of age, no difference emerged in males, while 6 out of 20 females who died of cardiovascular causes had thyroid autoantibodies, compared with 18% in the whole series. In a series of 97 hospital patients with myocardial infarction, 7 patients had thyroid autoantibodies as opposed to 12 antibody-positive subjects among controls matched for age and sex. Elevated TSH level appeared to be no better an indicator of cardiovascular morbidity or mortality than thyroid autoantibodies. It is concluded that thyroid autoimmunity may act as a cardiovascular risk factor under certain circumstances, but it does not have any general significance and the mechanism of action remains unclear.

In a double-blind trial, 327 patients (57 men) over 65 (mean age 79.5) years received all possible combinations of calcium carbonate 3 g, vitamin D3 1000 iu, methandienone 2.5 mg and/or placebos daily for 9 months. The higher incidence of bone fractures in the placebo group was not significant. Serum calcium, phosphorus, creatinine, aspartate aminotransferase and alkaline phosphatase were followed: the greatest changes occurred with methandienone, which thus reduced osteoporotic activity and increased the muscular mass most effectively; calcium carbonate had the poorest effect. Surprisingly, coronary mortality was higher among those taking all three active substances. With two treatments the increase was not significant, but when both the groups receiving a combination of any two of the treatments were compared with those taking only one or neither of these two treatments, a significant increase in coronary deaths was seen, most significant (P less than 0.001) in those receiving vitamin D3 and methandienone.

Pulsed field ablation (PFA) is an emerging technology for the treatment of atrial fibrillation (AF), for which pre-clinical and early-stage clinical data are suggestive of some degree of preferentiality to myocardial tissue ablation without damage to adjacent structures. Here in the MANIFEST-17K study we assessed the safety of PFA by studying the post-approval use of this treatment modality. Of the 116 centers performing post-approval PFA with a pentaspline catheter, data were received from 106 centers (91.4% participation) regarding 17,642 patients undergoing PFA (mean age 64, 34.7% female, 57.8% paroxysmal AF and 35.2% persistent AF). No esophageal complications, pulmonary vein stenosis or persistent phrenic palsy was reported (transient palsy was reported in 0.06% of patients; 11 of 17,642). Major complications, reported for ~1% of patients (173 of 17,642), were pericardial tamponade (0.36%; 63 of 17,642) and vascular events (0.30%; 53 of 17,642). Stroke was rare (0.12%; 22 of 17,642) and death was even rarer (0.03%; 5 of 17,642). Unexpected complications of PFA were coronary arterial spasm in 0.14% of patients (25 of 17,642) and hemolysis-related acute renal failure necessitating hemodialysis in 0.03% of patients (5 of 17,642). Taken together, these data indicate that PFA demonstrates a favorable safety profile by avoiding much of the collateral damage seen with conventional thermal ablation. PFA has the potential to be transformative for the management of patients with AF., (© 2024. The Author(s).)

Background: Ventricular extrasystoles (VESs) are common and often harmless in a healthy heart, but they can significantly affect the quality of life. If changes in lifestyle and antiarrhythmic medication are not enough, invasive and often curative catheter ablation can be considered. Better understanding of the conformation of VESs with a 12-lead ECG, as well as their precise localization, have increased their treatment with catheter ablation. Our goal was to determine whether the anatomical site of VES had an effect on procedure success. We also analyzed the safety of the procedure and patient-related factors affecting the results., Materials and Methods: In this retrospective study, we analyzed the medical records of 63 consecutive patients with multiple idiopathic VESs treated by catheter ablation at Heart Hospital, Tampere University Hospital, during 2017 and 2018. Patients with structural heart disease were excluded. Ablation success was estimated with two endpoints, primary and follow-up success., Results: The majority of the patients received treatment on the right ventricular outflow tract (66.7%), others on the left ventricle (17.5%), or the aortic cusp (9.5%). The site of origin remained unknown in four procedures (6.3% of patients). Primary success was observed in 48 procedures (76.2%). During the follow-up period of three months, the procedure was successful in 70.3% of the cases. The anatomical site of VES had no significant effect on either primary or follow-up success. Those with a successful follow-up result had a lower body mass index (BMI = 26.4) than those who had an unsuccessful result (BMI = 28.7; p =0.069); this did not reach statistical significance, potentially due to the small study population size. Complications were observed in three patients (4.5%). All of them were related to the catheter insertion site., Conclusions: For a symptomatic patient, catheter ablation is an effective and often fully curative treatment. The success rate was similar regardless of the site of VESs. This suggests that catheter ablation should also be assessed early on for other cases besides classic right ventricular outflow tract VESs. A high BMI was the only factor associated with a poor procedure success rate. The procedure itself is safe, and adverse effects are rare. The radiation dose is also low partly due to the current magnetic navigation method., Competing Interests: All the authors declare that they have no conflicts of interest., (Copyright © 2023 Aliisa Lönnrot et al.)

Purpose: Catheter ablation for atrial fibrillation (AF) is a standard procedure for maintaining sinus rhythm. The aim of this study was to evaluate treatment success and its predictors and to provide quality control data on complications and redo operations in a centre with an initially a low but currently high annual volume., Methods: Data on patients (n = 1,253) treated with catheter ablation for AF in Tays Heart Hospital between January 2010 and May 2018 was evaluated (n = 1178 ablation-naïve patients and n = 1514 AF ablations). Comprehensive data on patient characteristics, treatment results, redo operations and complications were collected. Treatment success (maintenance of sinus rhythm at 1 year) was evaluated among patients residing within the hospital district (45% of the entire study population)., Results: Treatment success was observed in approximately 62.9% of the ablation-naïve patients. Preoperative predictors of treatment success were paroxysmal AF type, previous use of antiarrhythmic drugs, left atrium diameter and age. The experience at the centre did not associate with the 1-year outcome. A relapse during the first 3-month blanking period was associated with a nine-fold risk of failure at 1 year (unadjusted OR 9.1, 95% CI 5.5-15.1, p < 0.001). The major complication rate was 4.5% (68/1514) with no deaths. Ten percent of the patients needed a redo procedure within the first year., Conclusions: Patient-related factors are the most significant predictors of treatment success. A relapse during a 3-month blanking period is associated with a very high risk of failure at 1 year., (© 2021. The Author(s).)

Background: Acute left circumflex coronary artery (LCx) occlusion is not easily detected by the standard 12-lead electrocardiogram (ECG)., Methods: In 16 patients continuous ECG recording was performed during balloon occlusion. The treated lesions were divided into proximal and distal based on the location of the ischemic segments with respect to the left obtuse margin of the heart., Results: Mean ΔST (=ST amplitude during inflation - pre-inflation ST) ≥0.5mm in both leads I and aVL predicted a proximal occlusion site with sensitivity of 62.5% (95% confidence interval [CI] 24.9-91.5%), specificity 100% (95% CI 63.1-100%), positive predictive value 100% (95% CI 47.8-100%), and negative predictive value 72.7% (95% CI 39-94%). In lead III, mean ΔST was +0.3mm in the distal and -0.2mm in the proximal group, respectively (p=0.036)., Conclusions: ST elevation in leads I and aVL is associated with myocardial ischemia at or proximal to the left obtuse margin., (Copyright © 2016 Elsevier Inc.

We compared the efficacy of the antihypertensive drug diltiazem in a slow release formulation administered once daily with its twice daily administration as monotherapy in 34 patients with mild to moderate essential hypertension. All subjects received placebo for three weeks before the randomised, double blind, crossover study, and their supine diastolic blood pressure (BP) ranged from 95 mmHg to 115 mmHg. After the patients had received the placebo for three weeks diltiazem was titrated in the open label treatment to either 120 mg or 180 mg twice daily until the target BP level was achieved. After the open three weeks' of treatment with diltiazem twice daily patients were allocated randomly for either once daily or twice daily administration. After a six week, double blind period, the treatment was changed according to the crossover design. With a dose of 120 mg or 180 mg twice daily patients' supine and standing BP readings were significantly lower than when they took the drug once daily. In the subgroup (n = 19) with the maximum dose of diltiazem given twice daily and once daily BP levels were lower in those subjects on twice daily treatment than in those treated once a day with the same total daily dose, the differences being significant. Administration of diltiazem once a day in a slow release formulation was not as effective as a twice daily dose when the dose titration was greatest or when compared with the same dosage (240 mg x 1/day or 120 mg x 2/day).

Fluoride has been used for the treatment of osteoporosis since 1961, because it increases trabecular bone mass in the spine and may be effective in the treatment of spinal osteoporosis. Fluoride treatment is still controversial because of its side effects, the high rate of non-responders, possible osteomalacic effect on bone, deleterious effects on cortical bone, and especially because of its uncertain effect on fracture rate. At present, fluoride therapy is highly questionable in the prophylaxis and treatment of osteoporosis.

Since dietary calcium had been reported to reduce plasma lipids, the effects of calcium carbonate (CaCO3, 2 g/day) and the calcium salt of p-chlorphenozyisobutyrate (Ca-CPIB, 2 g/day), both singly and in combination, were studied in outpatients with primary hyperlipidaemia. Three groups of five patients were followed in a double-blind cross-over study, in which placebo and the drugs were given alternately during four-week periods. The main results were: 1) CaCO3 alone did not produce any significant changes in plasma lipids. 2) Ca-CPIB reduced LDL-cholesterol in patients with type IIa and IIb by an average of 29 and 21%, respectively. It also lowered VLDL-triglyceride by 50% in type IIb and by 48% in four out of five patients with type IV. 3) The combination of CaCO3 and Ca-CPIB reduced LDL-cholesterol by 31 and 25% in types IIa and IIb, respectively. It also lowered VLDL-triglyceride by 48-52% in types IIa and by 46% in four out of five patients with type IIb. 4) Three out of five patients with type IV had a rise of LDL-cholesterol while on Ca-CPIB alone; two of the patients had the rise while on the combination. 5) After treatment with Ca-CPIB, either singly or in combination, there was a statistically significant lowering of ESR and of plasma inorganic phosphate and alkaline phosphatase. No clinical side effects were noted.

The antihypertensive efficacy and frequency of adverse reactions following administration of diltiazem in a new slow-release formulation were compared with placebo in 34 patients with mild to moderate essential hypertension in a randomized, double-blind, crossover study. After 6 weeks of treatment with diltiazem (240 or 360 mg/day), average supine blood pressure (BP) decreased from 165 +/- 21/101 +/- 5 mm Hg at baseline to 152 +/- 16/93 +/- 4 mm Hg compared with 160 +/- 19/100 +/- 7 mm Hg with placebo (p less than 0.01/p less than 0.001). Standing BP decreased from 162 +/- 20/107 +/- 6 mm Hg at baseline to 150 +/- 14/101 +/- 5 mm Hg compared to 159 +/- 18/107 +/- 8 mm Hg with placebo (p less than 0.01/p less than 0.001). The supine heart rate after diltiazem was 65 +/- 7 beats/min and after placebo 69 +/- 9 beats/min (p less than 0.01). There were no hematologic side effects. Only minor differences between diltiazem and placebo were observed in some of the biochemical laboratory values. Four patients were withdrawn due to side effects during treatment with diltiazem and 2 with placebo. Diltiazem in a slow-release formulation given twice a day lowered blood pressure significantly as monotherapy in patients with mild to moderate hypertension and was well tolerated.

One hundred patients (mean age 34 years, range from 12 to 70 years) were treated at Tampere University Hospital during the thirteen year period, 1972-1984. Our hospital takes responsibility for the treatment of patients with Crohn's disease found in an unselected population of 400,000 inhabitants. In 73% of cases Crohn's disease was diagnosed before the age of forty. The mean interval between the first clinical signs and the diagnosis was 3.3 years. In 57% of the patients the diagnosis was reached within one year. In nine patients the primary diagnosis was colitis ulcerosa. Most patient were anemic and were in the state of inflammation and/or catabolism suggested by low blood hemoglobin concentration and high ESR and CRP values on admission. Three percent of the patients had macroscopic Crohn's disease in all parts of the gastrointestinal tract, whereas 22% had it only in the small intestine and 18% only in the colon. Fifty of the hundred patients had lesions in the terminal ileum and 20% in the anus. The specific finding for the present series was a high frequency of rectal lesions, in 29% of the patients. Histologically the condition was more often (P less than 0.001) revealed by the laparatomy specimen than the endoscopic biopsy, which gave a positive histology more often (P less than 0.001) in the lower than in the upper gastrointestinal tract. No gastrointestinal malignancies were found.
