ABSTRACT

BACKGROUND: Diabetic patients with acute myocardial infarction (AMI) may have diminished pain or a higher frequency of asymptomatic infarctions. This appears to be a common clinical perception. METHODS: Data from two registries of AMI patients presenting in hospital (MITRA PLUS with 18786 patients; North German Registry, NGR, 1042 patients with detailed symptom interviews) were analyzed concerning symptoms of acute myocardial infarction in patients with diabetes mellitus (DM) and without diabetes (non-DM). RESULTS: DM patients were significantly older and more often female than non-DM. There were no differences in the frequency of pre-infarction angina between DM and non-DM (Mitra Plus). In NGR, severe angina during AMI occurred in 49.8% of DM and 46.3% of non-DM (n. s.). No chest pain was reported in 16.9% of DM and 15.0% of non-DM (n. s.). Extra-thoracic pain, dizziness, nausea, sweating, palpitations, radiation of angina and localization of radiating pain was not different between DM and non-DM patients. Severe dyspnea occurred in 29.5% of DM and 19.5% of non-DM patients (p = 0.003). CONCLUSIONS: Apart from a higher frequency of severe dyspnea in diabetics, there appears to be no difference in the clinical symptoms of AMI patients with and without diabetes mellitus. AMI with little or no angina was also frequently found in non-diabetics. In the hospital, diabetics with suspected AMI do not appear to need a special judgement of symptoms. This could accelerate access of diabetics to standard therapeutic procedures.

ABSTRACT

While a circadian rhythm in the onset of acute myocardial infarction (AMI) is well established, little is known about the variability of prehospital delay and decision processes. Seven hundred and thirty-nine consecutive AMI patients (median age 65.3 years; 30.2% women) with a median decision time of 60 min and a total prehospital delay of 180 min were studied. In 30.9% of patients onset of AMI symptoms was at night (10.00 p.m.-06.00 a.m.). At night patient decision time was significantly longer than during daytime (120 vs 45 min, difference 75 min; p < 0.001), total prehospital delay was prolonged accordingly (240 vs 170 min, difference 70 min; p < 0.001). The relative risk (RR; 95% confidence interval, CI) for a late decision (> 1 h) to seek medical care at night was significantly increased in females (RR 1.96; CI 1.07-3.61, p = 0.028), non-smokers (RR 2.49; CI 1.42-4.39, p = 0.001) and patients with radiation of anginal pain (RR 2.34; CI 1.32-4.15; p = 0.003). Of all patients with a late decision to seek medical care at night, 95.6% belonged to one of these groups. These variables were not significant for early or late decisions during daytime. Decision processes of AMI patients may be different during daytime and at night. In conclusion, in AMI patients, decision time to seek medical help is prolonged at night. Simple clinical variables (female sex, non-smokers, radiation of anginal pain) identify patients at high risk for a late decision at night. This information should be included into public and individualized education campaigns.

ABSTRACT

BACKGROUND: Early reperfusion treatment in acute myocardial infarction (AMI) preserves ventricular function and saves lives. After onset of AMI symptoms, patients often delay for hours until the decision to seek medical help. AIM: Of the MI-heart (Myocardial Infarction--HElp seeking And ReacTions) study was to identify factors determining patient decision delay. METHODS: 739 consecutive patients with confirmed AMI (median age 65.3 years, 30.2% females) were studied after transfer from the intensive care unit. A standardized interview covered AMI symptoms, attitudes toward symptoms, coping strategies, and clinical and sociodemographic variables. RESULTS: Of patients, 93.3% knew an AMI could be deadly. 43.9% of the patients who suspected an AMI, and knew it could be deadly, decided late (> 1 hour) to seek medical help. In univariate analyses, attitudes toward symptoms and coping strategies had the highest impact on a late decision. Stepwise logistic regression identified the following independent contributors to a late decision to seek medical help (relative risk, 95% confidence interval): wanting to wait and see (3.53; 2.32-5.39), not taking symptoms seriously (2.47; 1.64-3.72), not wanting to bother anybody (2.14; 1.29-3.57), symptoms improving at first (2.33; 1.52-3.56), asking others for advice (0.46; 0.30-0.71), taking pain medication (2.01; 1.01-4.03), age > 65 years (1.69; 1.17-2.44), very strong intensity of angina (0.60; 0.42-0.87). CONCLUSIONS: Emotional attitudes to AMI symptoms and inadequate coping strategies are the major determinants of patient decision delay. They should be considered as a key factor in patient and public education. Modification of these emotional factors might best be achieved by an individualized approach.

ABSTRACT

Hyperthyroidism is usually associated with tachycardia, hypothyroidism with bradycardia. After observing clinically inapparent hyperthyroidism in patients requiring pacemaker implantation, we studied the occurrence of hyperthyroidism in patients receiving a first permanent pacemaker. Of 237 patients (age 71.4 +/- 8.9 years; 54.9% females), 16 (6.75%) had subclinical (TSH < 0.1 mE/l and fT3 < or = 9.0 pmol/l) and 4 (1.69%) overt hyperthyroidism (TSH < 0.1 mE/l and fT3 > 9.0 pmol/l). Prevalence of hyperthyroidism was similar to that in the general population. Compared to euthyroid patients, in the patients with subclinical or overt hyperthyroidism there were significantly more females (n = 16) than males (n = 4; p = 0.018). Hyperthyroid patients were older (75.0 +/- 9.6 vs. 70.7 +/- 8.9 years; p = 0.015). At follow-up, all patients had a relevant proportion of pacemacer-induced beats. Clinical signs of hyperthyroidism or cardiac symptoms were not different between groups. In conclusion, bradycardia does not exclude the presence of hyperthyroidism. Temporary pacing is recommended in thyreotoxicosis with bradycardia. In contrast, primary implantation of a permanent pacemaker appears to be adequate in patients with bradycardia, cardiovascular disease and an additional diagnosis of hyperthyroidism.

ABSTRACT

In the years after 1989 major political and socioeconomic changes have taken place in East Germany. In parallel, emergency medical services (EMS) were restructured according to western standards. In Stralsund the EMS was restructured from a single to a two tier system with implementation of a second ambulance base in 1990. The number of household telephone extensions more than doubled. To analyze the effects of these changes, patients receiving advanced life support (ALS) for out-of-hospital cardiac arrest of cardiac origin (OHCA) between 1984 and 1988, and from 1991 to 1997 were studied. Adjusted per 100,000 inhabitants, the number of OHCA patients receiving ALS increased from 11 per year before 1989 to 52 per year after 1990 (P < 0.01). Survival without relevant neurologic defects was achieved in 3.7% (2/53) of patients before 1989 and in 8.1% (22/273) after 1990. Response time of the ALS unit shortened from 11.0 +/- 1.4 to 9.0 +/- 0.4 min (n.s.), while response time of any EMS shortened from 11.0 +/- 1.4 to 6.1 +/- 0.3 min (P < 0.005). Adjusted for observation period and population served, there was a 10-fold increase in the number of resuscitations attempted at home and an 8-fold increase in the absolute number of OHCA survivors without relevant neurological defects. In parallel to socioeconomic changes, the restructuring of the EMS in Stralsund and the rapid expansion of the telephone network led to a significant increase in the number of patients successfully resuscitated from OHCA. If the present results can be transferred to other former socialist countries of East and Middle Europe, they may have important implications for the EMS in these regions.

ABSTRACT

Patients with paroxysmal supraventricular tachycardia (SVT) may have a polyuria after termination of tachycardia. There is increasing evidence that the renal peptide urodilatin (ANP (95-126))--and not plasma ANP (ANP (99-126))--is the member of the natriuretic peptide family mediating natriuresis and diuresis in man. In patients with SVT we, therefore, analyzed the relationship between diuresis, natriuresis, plasma ANP, urinary urodilatin excretion and renal excretion of cyclic GMP, the second messenger in the ANP system. During and after clinical presentation with spontaneously occurring SVT, two patients with AV-nodal and one patient with atrioventricular reentry tachycardia (heart rate 160 to 200 bpm) were studied. Urinary urodilatin excretion was correlated to diuresis (r = 0.73) and natriuresis (r = 0.93); similarly urinary cyclic GMP excretion was related to diuresis (r = 0.80) and natriuresis (r = 0.87; p < 0.001, respectively). In contrast, there was no significant correlation between plasma ANP concentrations and diuresis (r = 0.28, n.s.) or natriuresis (r = 0.11, n.s.). As an explorative analysis, stepwise multiple linear regression identified urinary urodilatin as the most important contributor to diuresis and natriuresis after SVT. These data on polyuria after spontaneous SVT further support the view that in man urodilatin is the member of the natriuretic peptide family participating in kidney physiology.

ABSTRACT

Primary chylopericardium is a rare disease with a highly variable clinical course. We report on a 24-year old female with chylopericardium detected during a pulmonary infection. Despite successful treatment of the infectious disease, the chylopericardium persisted and led to cardiac tamponade. From this case, as well as from the literature, it is intriguing to postulate an inflammatory injury of preexisting anomalous lymphatic vessels leading to onset or aggravation of primary chylopericardium. The clinical hallmark of chylopericardium is a milky white, but odorless pericardial fluid at pericardiocentesis. For cases where conservative treatment and pericardiocentesis fail, we newly introduced the method of pericardio-peritoneal shunting by a pericardial window. With postoperative reaccumulation of pericardial fluid, total parenteral nutrition followed by medium chain triglyceride diet was successfully reinitiated. This combined surgical and conservative approach was performed for the first time and may have helped to avoid the more aggressive treatment of thoracic duct ligation and resection. During 2 years of follow-up the patient was asymptomatic and had no recurrence of pericardial effusion.
