    • BACKGROUND The comparative efficacy of various anticoagulation strategies has not been clearly established in patients with acute myocardial infarction who are undergoing percutaneous coronary intervention (PCI) according to current practice, which includes the use of radial-artery access for PCI and administration of potent P2Y 12 inhibitors without the planned use of glycoprotein IIb/IIIa inhibitors. METHODS In this multicenter, randomized, registry-based, open-label clinical trial, we enrolled patients with either ST-segment elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) who were undergoing PCI and receiving treatment with a potent P2Y(12) inhibitor (ticagrelor, prasugrel, or cangrelor) without the planned use of glycoprotein IIb/IIIa inhibitors. The patients were randomly assigned to receive bivalirudin or heparin during PCI, which was performed predominantly with the use of radial-artery access. The primary end point was a composite of death from any cause, myocardial infarction, or major bleeding during 180 days of follow-up. RESULTS A total of 6006 patients (3005 with STEMI and 3001 with NSTEMI) were enrolled in the trial. At 180 days, a primary end-point event had occurred in 12.3% of the patients (369 of 3004) in the bivalirudin group and in 12.8% (383 of 3002) in the heparin group (hazard ratio, 0.96; 95% confidence interval [CI], 0.83 to 1.10; P = 0.54). The results were consistent between patients with STEMI and those with NSTEMI and across other major subgroups. Myocardial infarction occurred in 2.0% of the patients in the bivalirudin group and in 2.4% in the heparin group (hazard ratio, 0.84; 95% CI, 0.60 to 1.19; P = 0.33), major bleeding in 8.6% and 8.6%, respectively (hazard ratio, 1.00; 95% CI, 0.84 to 1.19; P = 0.98), definite stent thrombosis in 0.4% and 0.7%, respectively (hazard ratio, 0.54; 95% CI, 0.27 to 1.10; P = 0.09), and death in 2.9% and 2.8%, respectively (hazard ratio, 1.05; 95% CI, 0.78 to 1.41; P = 0.76). CONCLUSIONS Among patients undergoing PCI for myocardial infarction, the rate of the composite of death from any cause, myocardial infarction, or major bleeding was not lower among those who received bivalirudin than among those who received heparin monotherapy.

  • Bivalirudin versus heparin monotherapy in non-ST-segment elevation myocardial infarction
  • 2019
  • Ingår i: ; 8:6, s. 492-501
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The optimal anti-coagulation strategy for patients with non-ST-elevation myocardial infarction treated with percutaneous coronary intervention is unclear in contemporary clinical practice of radial access and potent P2Y12-inhibitors. The aim of this study was to investigate whether bivalirudin was superior to heparin monotherapy in patients with non-ST-elevation myocardial infarction without routine glycoprotein IIb/IIIa inhibitor use.METHODS: In a large pre-specified subgroup of the multicentre, prospective, randomised, registry-based, open-label clinical VALIDATE-SWEDEHEART trial we randomised patients with non-ST-elevation myocardial infarction undergoing percutaneous coronary intervention, treated with ticagrelor or prasugrel, to bivalirudin or heparin monotherapy with no planned use of glycoprotein IIb/IIIa inhibitors during percutaneous coronary intervention. The primary endpoint was the rate of a composite of all-cause death, myocardial infarction or major bleeding within 180 days.RESULTS: A total of 3001 patients with non-ST-elevation myocardial infarction, were enrolled. The primary endpoint occurred in 12.1% (182 of 1503) and 12.5% (187 of 1498) of patients in the bivalirudin and heparin groups, respectively (hazard ratio of bivalirudin compared to heparin treatment 0.96, 95% confidence interval 0.78-1.18, p=0.69). The results were consistent in all major subgroups. All-cause death occurred in 2.0% versus 1.7% (hazard ratio 1.15, 0.68-1.94, p=0.61), myocardial infarction in 2.3% versus 2.5% (hazard ratio 0.91, 0.58-1.45, p=0.70), major bleeding in 8.9% versus 9.1% (hazard ratio 0.97, 0.77-1.24, p=0.82) and definite stent thrombosis in 0.3% versus 0.2% (hazard ratio 1.33, 0.30-5.93, p=0.82).CONCLUSION: Bivalirudin as compared to heparin during percutaneous coronary intervention for non-ST-elevation myocardial infarction did not reduce the composite of all-cause death, myocardial infarction or major bleeding in non-ST-elevation myocardial infarction patients receiving current recommended treatments with modern P2Y12-inhibitors and predominantly radial access.

  • Disturbed glucose metabolism is associated with left ventricular dysfunction using tissue Doppler imaging in patients with myocardial infarction
  • 2007
  • Ingår i: Clinical Physiology and Functional Imaging. - 1475-0961 .- 1475-097X. ; 27:1, s. 60-66
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To investigate the association between glucose abnormalities and left ventricular (LV) function assessed by tissue Doppler imaging (TDI) in patients with previous history of myocardial infarction and without known diabetes mellitus. Patients and methods: In a cross-sectional study, 123 patients, aged 31-80 years, with a history of previous myocardial infarction and without known diabetes mellitus were examined with TDI echocardiography. A standard oral glucose test (OGTT) with 75 g of glucose was performed. Results: Two-hour plasma glucose were significantly and negatively associated with TDI parameters such as LV ejection time; early diastolic filling velocity (E'-v); ratio of the early to late diastolic filling velocity (E'/A') and positively associated with regional myocardial performance index (MPI) (P < 0.05). Left ventricular ejection time and MPI were significantly higher; E'/A' and E'-v were significantly lower in patients with disturbed glucose metabolism compared with patients with normal glucose tolerance (P < 0.01). These differences remain significant also when the patients with DM were excluded. Conclusions: The present study demonstrates that disturbed glucose metabolism is associated with more pronounced LV dysfunction using TDI in patients with myocardial infarction. These abnormalities in LV function were more common not only in subjects with diabetes, but also in patients with prediabetic condition, impaired glucose intolerance.

  • Intima-Media Thickness of Common Carotid and Brachial Arteries and Prothrombin Fragment 1+2 Are Associated with Left Ventricular Diastolic Dysfunction in Patients with Myocardial Infarction
  • 2010
  • Ingår i: Echocardiography. - 0742-2822 .- 1540-8175. ; 27:6, s. 651-658
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To investigate the association between intima-media thickness of brachial and common carotid arteries and factors of the coagulation- and fibrinolysis-system with left ventricular diastolic dysfunction in patients with a previous myocardial infarction. Patients and methods: One hundred and twenty three patients, men (76%) and women (24%) aged between 32and 81 years with a history of previous acute myocardial infarction were included. B-mode ultrasound of common carotid and brachial arteries and echocardiography with tissue Doppler imaging (TDI) were evaluated. Factors of the coagulation- and fibrinolysis-system were also measured. Results: In patients with previous myocardial infarction, late diastolic filling time was significantly and positively associated with log Prothrombin fragment 1 + 2 (P < 0.001) and with calculated intima-media area (cIMa) of the both common carotid and brachial arteries (P < 0.05). Mitral early-to-late flow velocity ratio (E/A) was significantly and negatively associated with log Prothrombin fragment 1 + 2 (P < 0.001), total cholesterol and cIMa of the both common carotid and brachial arteries (P < 0.05). Moreover both late diastolic filling time and mitral E/A correlated significantly with age and systolic blood pressure. In stepwise multiple regression analysis, log Prothrombin fragment 1 + 2 remained the only variable with independent significant correlation to late diastolic filling time and mitral E/A. Conclusions: In a population sample of patients with myocardial infarction, late diastolic filling time and mitral E/A were associated with cIMa of common carotid and brachial arteries, systolic blood pressure, and prothrombin fragment 1 + 2, suggesting a relationship between diastolic dysfunction, thrombin generation and atherosclerosis.

  • Increased Inflammatory Activity in Patients 3 Months after Myocardial Infarction with Nonobstructive Coronary Arteries
  • 2019
  • Ingår i: Clinical Chemistry. - : AMER ASSOC CLINICAL CHEMISTRY. - 0009-9147 .- 1530-8561. ; 65:8, s. 1023-1030
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Around 5%-10% of patients with myocardial infarction (MI) present with nonobstructive coronary arteries (MINOCA). We aimed to assess pathophysiological mechanisms in MINOCA by extensively evaluating cardiovascular biomarkers in the stable phase after an event, comparing MINOCA patients with cardiovascular healthy controls and MI patients with obstructive coronary artery disease (MI-CAD).METHODS: Ninety-one biomarkers were measured with a proximity extension assay 3 months after MI in 97 MINOCA patients, 97 age-and sex-matched MI-CAD patients, and 98 controls. Lasso analyses (penalized logistic regression models) and adjusted multiple linear regression models were used for statistical analyses.RESULTS: In the Lasso analysis (MINOCA vs MI-CAD), 8 biomarkers provided discriminatory value: P-selectin glycoprotein ligand 1, C-X-C motif chemokine 1, TNF-related activation-induced cytokine, and pappalysin-1 (PAPPA) with increasing probabilities of MINOCA, and tissue-type plasminogen activator, B-type natriuretic peptide, myeloperoxidase, and interleukin-1 receptor antagonist protein with increasing probabilities of MI-CAD. Comparing MINOCA vs controls, 7 biomarkers provided discriminatory value: N-terminal pro-B-type natriuretic peptide, renin, NF-kappa-B essential modulator, PAPPA, interleukin-6, and soluble urokinase plasminogen activator surface receptor with increasing probabilities of MINOCA, and agouti-related protein with increasing probabilities of controls. Adjusted multiple linear regression analyses showed that group affiliation was associated with the concentrations of 7 of the 8 biomarkers in the comparison MINOCA vs MI-CAD and 5 of the 7 biomarkers in MINOCA vs controls.CONCLUSIONS: Three months after the MI, the biomarker concentrations indicated greater inflammatory activity in MINOCA patients than in both MI-CAD patients and healthy controls, and a varying degree of myocardial dysfunction among the 3 cohorts.

  • Combination of contrast-enhanced wall motion analysis and myocardial deformation imaging during dobutamine stress echocardiography
  • 2015
  • Ingår i: European Heart Journal Cardiovascular Imaging. - 2047-2404 .- 2047-2412. ; 16:1, s. 88-95
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The combination of deformation analysis with conventional wall motion scoring (WMS) has been shown to increase the diagnostic sensitivity of dobutamine stress echocardiography (DSE). The feasibility and diagnostic power of WMS is largely improved by contrast agents; however, they are not used in combination with deformation analysis, as contrast agents are generally considered to render strain measurement unfeasible. Aims To assess the feasibility of tissue velocity (TVI)- and 2D speckle tracking (ST)-based strain analysis during contrast-enhanced DSE; and to show whether there is an incremental value in combining deformation analysis with contrast-enhanced WMS. Methods DS echocardiograms containing native, tissue Doppler, and contrast-enhanced loops of 60 patients were analysed retrospectively. The feasibility of WMS, TVI-, and ST-strain measurement was determined in 40 patients according to pre-defined criteria. The diagnostic ability of a combined protocol integrating data from contrast-WMS and TVI-strain measurement was then compared with contrast-WMS alone in all 60 patients, using coronary angiograms as a gold standard. Results Both TVI- and ST-based strain analysis were feasible during contrast-DSE (feasibility at peak stress: 87 and 75%). At the patient level, the diagnostic accuracy of the combined method did not prove superior to contrast-WMS (82 vs. 78%); a trend towards improved sensitivity and specificity for detecting coronary artery disease in the right coronary artery circulation (sensitivity: 85 vs. 77%, P = NS; specificity: 96 vs. 94%) was, however, observed. Conclusion Both TVI- and ST-based myocardial deformation analysis are feasible during contrast-enhanced DSE, however, our results fail to demonstrate a clear diagnostic benefit of additional strain analysis over expert WMS alone.

  • Personality Traits in Patients with Myocardial Infarction with Nonobstructive Coronary Arteries.
  • 2019
  • Ingår i: The American journal of medicine. - 1555-7162 .- 0002-9343. ; 132:3, s. 374-381
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of this study was to describe type A behavior pattern and trait anger in patients with myocardial infarction with nonobstructive coronary arteries (MINOCA) and compare them with patients with coronary heart disease and healthy controls. Type A behavior pattern and anger have been linked to coronary heart disease in previous studies. This is the first study to assess type A behavior pattern and trait anger in MINOCA patients.One hundred MINOCA patients, consecutively recruited during 2007-2011 at 5 coronary care units in Stockholm, were matched for sex and age to 100 coronary heart disease patients and 100 healthy controls. All participants completed the Bortner Rating Scale to quantify type A behavior pattern and the Spielberger Trait Anger Scale to quantify anger 3 months after the acute event.MINOCA patients' Bortner Rating Scale score was 70.9 ± 10.8 (mean ± SD) and Spielberger Trait Anger Scale score was 14 (12-17) (median; interquartile range). Coronary heart disease patients' Bortner Rating Scale score was 70.5 ± 10.2 and Spielberger Trait Anger Scale score was 14 (12-17). Healthy controls' Bortner Rating Scale score was 71.9 ± 9.1 and Spielberger Trait Anger Scale score was 13 (11-16).We found no significant differences in Bortner Rating Scale score and Spielberger Trait Anger Scale score among MINOCA, coronary heart disease patients, and healthy controls, regardless of whether total scores, subscales, or cutoffs were used to classify type A behavior pattern and trait anger. However, we cannot exclude the existence of an occasional episode of anger or mental stress in relation to the coronary event. This is the first study to assess type A behavior pattern and trait anger in patients with MINOCA, and future studies need to confirm the current findings before any firm conclusions can be made.

  • Radial versus femoral access in patients with acute coronary syndrome undergoing invasive management : A prespecified subgroup analysis from VALIDATE-SWEDEHEART
  • 2019
  • Ingår i: ; 8:6, s. 510-519
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: In the Bivalirudin versus Heparin in ST-Segment and Non-ST-Segment Elevation Myocardial Infarction in Patients on Modern Antiplatelet Therapy in the Swedish Web System for Enhancement and Development of Evidence-based Care in Heart Disease Evaluated according to Recommended Therapies Registry Trial (VALIDATE-SWEDEHEART), bivalirudin was not superior to unfractionated heparin in patients with acute coronary syndrome undergoing invasive management. We assessed whether the access site had an impact on the primary endpoint of death, myocardial infarction or major bleeding at 180 days and whether it interacted with bivalirudin/unfractionated heparin.Methods and results: A total of 6006 patients with acute coronary syndrome planned for percutaneous coronary intervention were randomised to either bivalirudin or unfractionated heparin. Arterial access was left to the operator discretion. Overall, 90.5% of patients underwent transradial access and 9.5% transfemoral access. Baseline risk was higher in transfemoral access. The unadjusted hazard ratio for the primary outcome was lower with transradial access (hazard ratio 0.53, 95% confidence interval 0.43-0.67, p<0.001) and remained lower after multivariable adjustment (hazard ratio 0.56, 95% confidence interval 0.52-0.84, p<0.001). Transradial access was associated with lower risk of death (hazard ratio 0.41, 95% confidence interval 0.28-0.60, p<0.001) and major bleeding (hazard ratio 0.57, 95% confidence interval 0.44-0.75, p<0.001). There was no interaction between treatment with bivalirudin and access site for the primary endpoint (p=0.976) or major bleeding (p=0.801).Conclusions: Transradial access was associated with lower risk of death, myocardial infarction or major bleeding at 180 days. Bivalirudin was not associated with less bleeding, irrespective of access site.

  • Impaired glucose tolerance in ischemic heart disease
  • 2005
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Background: Diabetes mellitus (DM) and impaired glucose tolerance test (IGT) are well known risk factors for cardiovascular disease (CVD). Individuals with IGT, a prediabetic state, are asymptomatic during many years and they often remain undiagnosed until they have developed overt diabetes or cardiovascular complications. Patients and methods: A total 123 patients, aged 31-80 years with a previous acute myocardial infarction (MI) but without a known DM were examined. A standard oral glucose test (OGTT) was performed. Calculated intimamedia (clMa) of the brachial and common carotid arteries, flow-mediated dilation (FMD) of the brachial artery, left ventricular dimensions and systolic function were examined. Left ventricular diastolic function was evaluated by tissue velocity echocardiography. Microalbuminuria (MA) was defined as excretion of 20-200 mug albumin/min. Results: The prevalence of DM and IGT in patients discharged from the CCU after MI without known DM diagnosis was high (38%). A fasting plasma glucose (PG) alone failed to identify more than 80% of the patients with abnormal glucose metabolism in this study. A multiple stepwise regression analysis revealed an independent and significant association between 2h PG and CRP (P <0.05). In the whole group calculated intimamedia area was associated with 2h PG after the glucose load (P <0.05). Both cIMa of the common carotid artery and the cIMa of the brachial artery were independently and significantly associated with left ventricular septum thickness. Microalbuminuria (MA) was present in 11% of patients. Patients with MA had significantly higher levels of 2h PG, lower displacement of the atrioventricular (AV) plane by M-mode echocardiography, thicker LV septum wall and a higher prevalence of impaired glucose tolerance compared with those with normoalbuminuria (p<0.05). Urinary albumin excretion (UAE) was significantly and positively associated with cIMa in both brachial and common carotid arteries, age and interventricular septum thickness. 2-h PG was significantly and negatively associated with diastolic TDI parameters such as early diastolic filling velocity (E-v), ratio of the early to late diastolic filling velocity (E'/A') and positively associated with Tei index (p<0.05). Left ventricular ejection time and Teiindex were significantly higher, E'/A' and E-v were significantly lower in patients with disturbed glucose metabolism compared with patients with normal glucose tolerance (p<0.01). These differences also remained significant when patients with DM were excluded from analysis. Conclusions: The prevalence of abnormal glucose tolerance was high in patients discharged after MI without known DM. Glucose intolerance was associated with inflammation, surrogate variables for atherosclerosis, microalbuminuria and LV diastolic dysfunction. In this population FMD was probably not a reliable marker, since FMD is a functional parameter of the arterial system, particularly well suited for the study of the earlier stages of atherosclerosis in children and young adults without stiff arteries.
