Abstract Background In multiple studies, the potential relationship between daylight saving time (DST) and the occurrence of acute myocardial infarction (MI) has been investigated, with mixed results. Using the Dutch Percutaneous Coronary Intervention (PCI) registry facilitated by the Netherlands Heart Registration, we investigated whether the transitions to and from DST interact with the incidence rate of PCI for acute MI. Methods We assessed changes in hospital admissions for patients with ST-elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) undergoing PCI between 1 January 2015 and 31 December 2018. We compared the incidence rate of PCI procedures during the first 3 or 7 days after the transition with that during a control period (2 weeks before transition plus second week after transition). Incidence rate ratio (IRR) was calculated using Poisson regression. Potential gender differences were also investigated. Results A total of 80,970 PCI procedures for STEMI or NSTEMI were performed. No difference in incidence rate a week after the transition to DST in spring was observed for STEMI (IRR 0.95, 95% confidence interval (CI) 0.87–1.03) or NSTEMI (IRR 1.04, 95% CI 0.96–1.12). After the transition from DST in autumn, the IRR was also comparable with the control period (STEMI: 1.03, 95% CI 0.95–1.12, and NSTEMI: 0.98, 95% CI 0.91–1.06). Observing the first 3 days after each transition yielded similar results. Gender-specific results were comparable. Conclusion Based on data from a large, nationwide registry, there was no correlation between the transition to or from DST and a change in the incidence rate of PCI for acute MI.

AbstractBackgroundThe associations between incidence of acute myocardial infarction (AMI) and the ambient temperature were mixed in prior studies.MethodsData of 2033 consecutive admissions of AMI in a central tertiary hospital in North China from 1st Jan 2003 to 31st Dec 2011 were collected. The weather data in this period were from the local meteorological department. Based on the ambient temperature information, we defined several ambient temperature indices, including daily average temperature, extremely low temperature, and daily temperature range, then characterized the independent associations between them and the incidence of AMI.ResultsThe daily average temperature one day before was independently associated with AMI incidence rate: a rise of 5°C of the daily average temperature led to a 5% decrease in AMI admissions. Daily average temperature and temperature range two days before were independently associated with AMI incidence rate: a rise of 5°C of the daily average temperature led to a fall of 6% in AMI admissions, and a rise of 2°C of the daily temperature range led to a rise of 4% in AMI admission.ConclusionLow ambient temperature has substantial association with AMI, and can play an important role in warning and forecasting the incidence.

The Metabolic Syndrome

Background: The Metabolic Syndrome (METS) is a specific clustering of cardiovascular risk factors in the same person (abdominal obesity, atherogenic dyslipidemia, elevated Blood Pressure (BP), Insulin Resistance (IR), and a proinflammatory state. A recent review of insulin resistance syndrome revealed a rapid escalation of this syndrome among Indians and the prevalence of predominant component of METS varies from region to region. Hence the present study was undertaken to assess the incidence of Metabolic Syndrome and prognosis of metabolic syndrome among acute myocardial infarction patients.Methods: A longitudinal study was carried among Acute myocardial infarction patients, who were admitted to ICCU of Shri. B. M. Patil Hospital and Research Centre, Bijapur during November 2009 to March 2011. Sample size was calculated using the formula: n=4pq/L2. Sample size required was 92. Descriptive statistics and Inferential statistics were used to analyse the results.Results: The incidence rate of METS among AMI in our study was 48.7%.  The complications were more common in METS group compared to those without METS groups. Recovery was better among those without METS group. There was a statistically significant association between complications and status of METS. The past history of DM was more common in METS. Hyperglycemia among the components of METS has strongest association with the outcome of death in patients of AMI.Conclusions: The metabolic syndrome is a highly prevalent condition among the patients with acute myocardial infarction and has detrimental impact on outcome Metabolic syndrome is also associated with a higher risk of severe heart failure and death.

Acute Heart Failure (AHF) is a common rapid complication of Acute Myocardial Infarction (AMI). Myocardial dysfunction leads to pathologic remodeling of the heart, which causes AHF. Growth differentiation factor-15 (GDF-15) is expressed by cardiomyocytes and upregulated due to injury and cardiomyocyte damage. Thus, it can be used as a predictor of severe heart damage. This study aimed to determine the correlation between GDF-15 levels and the incidence rate of post-AMI AHF. This prospective cohort study was performed in patients with AMI treated in Dr. Moewardi Hospital from August to September 2019. The Kolmogorov-Smirnov normality test was used. Bivariate analysis was applied for Hazard Ratio (HR) with 95% CI. The GDF-15 cut-off used the ROC curve. The Cox Regression Proportional Hazard Model was used for multivariable analysis. The significance value was p <0.05. During the study, there were a total of 74 subjects. Bivariate analysis showed significant correlation between serum GDF-15 levels and hypertension history to the incidence of post-AMI AHF [HR=3.259; 95%CI (1.1558–6.819); p=0.002] and [HR=3.293; 95%CI (1.489-7.282); p=0.003]. Multivariate analysis showed that both variables had a similar strength of the correlation. The risk and the incidence rate of AHF were three times higher in AMI subjects with a history of hypertension and elevated GDF-15 levels. High serum GDF-15 levels and a history of hypertension can be predictors of post-AMI AHF.

Background We updated the information on trends of incident acute myocardial infarction in Norway, focusing on whether the observed trends during 2001–2009 continued throughout 2014. Methods All incident (first) acute myocardial infarctions in Norwegian residents age 25 years and older were identified in the Cardiovascular Disease in Norway 1994–2014 project. We analysed overall and age group-specific (25–64 years, 65–84 years and 85 + years) trends by gender using Poisson regression analyses and report the average annual changes in rates with their 95% confidence intervals. Results During 2001–2014, 221,684 incident acute myocardial infarctions (59.4% men) were identified. Hospitalised cases accounted for 79.9% of all incident acute myocardial infarctions. Overall, incident acute myocardial infarction rates declined on average 2.6% per year (incidence rate ratio 0.974, 95% confidence interval 0.972–0.977) in men and 2.8% per year (incidence rate ratio 0.972, 95% confidence interval 0.971–0.974) in women, contributed by declining rates of hospitalisations (1.8% and 1.9% per year in men and women, respectively) and deaths (6.0% and 5.8% per year in men and women, respectively). Declining rates were observed in all three age groups. The overall acute myocardial infarction incidence rates continued to decline from 2009 onwards, with a steeper decline compared to 2001–2009. During 2009–2014, gender-adjusted acute myocardial infarction incidence among adults age 25–44 years declined 5.3% per year, contributed mostly by declines in hospitalisation rates (5.1% per year). Conclusion Acute myocardial infarction incidence rates continued to decline after 2009 in Norway in both men and women. The decline started to involve individuals aged 25–44 years, marking a turning point in the previously reported stagnation of rates during 2001–2009.

Introduction. The aim of this study was to investigate the annual incidence of hospital morbidity and mortality rates of acute myocardial infarction (AMI) in the population of Nis who were treated at the Cardiology Clinic in Nis during the period 1974-2000. Material and Methods. A retrospective clinical-epidemiological study was carried out in the population of the city of Nis aged 30 years and over. The number of citizens of Nis, aged 30 years and over, was 71.500 in 1974, and 100.000 in 2000, while the male to female ratio was 48 %:52%. Results. During the period from 1974 to 2000, 4319 patients of both sexes with AMI received hospital treatment. The average annual incidence rate was 159.92 per 100.000 inhabitants aged 30 years and over. The average annual incidence of AMI showed a trend of progressive increase, and in 2000 it was 274.87 (2.7 times higher than in 1974 - 102.19). The average annual mortality for both sexes was 11.57% (9.82% for males and 15.89% for females). The female mortality rate was significantly higher (p< 0.001). Conclusion. Trends in annual incidence rate of AMI in the population of the city of Nis aged 30 years and over are characterized by progressive increase during the period from 1974 to 2000. The trend line: yt = 159.92+6.2432x shows that without primary prevention further increase in the incidence of AMI can be expected. .

The pathogenesis of the arteriosclerosis in the acute myocardial infarction is the matter of the extensive survey with the transmission electron microscopy in experimental and clinical materials. In the previous communication,the authors have clarified that the two types of the coronary vascular changes could exist. The first category is the case in which we had failed to observe no occlusive changes of the coronary vessels which eventually form the myocardial infarction. The next category is the case in which occlusive -thrombotic changes are observed in which the myocardial infarction will be taken placed as the final event. The authors incline to designate the former category as the non-occlusive-non thrombotic lesions. The most important findings in both cases are the “mechanical destruction of the vascular wall and imbibition of the serous component” which are most frequently observed at the proximal portion of the coronary main trunk.
