Dual antiplatelet therapy in patients with cirrhosis and acute myocardial infarction - A 13-year nationwide cohort study.

ABSTRACT:

Background

Patients with cirrhosis and acute myocardial infarction (AMI) present dilemma whether dual antiplatelet therapy (DAPT) should be used.

Methods

Electronic medical records between 2001-2013 were retrieved from Taiwan National Health Insurance Research Database. Patients were excluded for missing information, age <20 years old, history of AMI, liver transplant, autoimmune disease, coagulopathy, taking DAPT 3 months before index date, follow-up <3 months, anticoagulation user, without DAPT, and events of myocardial infarction (MI), ischemic stroke, major bleeding, and heart failure within 3-month of enrollment. Primary outcomes were 1-year all-cause mortality, recurrent MI, major bleeding, and gastrointestinal bleeding.

Results

A total of 150,887 patients with AMI retrieved. After exclusion criteria and propensity score-matching, 914 cirrhotic and 3,656 non-cirrhotic patients with AMI on DAPT were studied. During 1-year follow-up, there was significantly increased mortality in cirrhotic patients compared to non-cirrhotic patients (HR = 1.49, 95% CI = 1.28-1.74). There was significantly decreased recurrent MI in cirrhotic patients compared to non-cirrhotic patients (subdistribution HR [SHR] = 0.71, 95% CI = 0.54-0.92). However, non-significantly increased major bleeding (SHR = 1.23, 95% CI = 0.87-1.73) and significantly increased gastrointestinal bleeding (SHR = 1.49, 95% CI = 1.31-1.70).

Conclusions

In cirrhotic patients with AMI, DAPT offers benefit with decreased recurrent MI at the expense of increased gastrointestinal bleeding.

Project description:Background It is not clear whether β1-selective or nonselective β-blockers should be used in patients with cirrhosis and acute myocardial infarction. Methods and Results Medical records were retrieved from Taiwan NHIRD (National Health Insurance Research Database) during 2001-2013. Patients were excluded for age <20, previous acute myocardial infarction, contraindication to β-blockers, chronic obstructive pulmonary disease, asthma, or atrioventricular conduction disease. Patients who died during index admission, had a follow-up <6 months, had a medication ratio of either β1-selective or nonselective β-blocker <80%, or who switched between β-blockers were also excluded. Patients on β1-selective blockers and nonselective β-blockers were propensity score matched and compared for outcome. Primary outcomes were 1- and 2-year cardiovascular events, liver adverse outcomes, and all-cause mortality. A total of 203 595 patients with acute myocardial infarction were enrolled, of whom 6355 had cirrhosis. After screening for exclusion criteria, 1769 patients (655 patients on β-blockers and 1114 patients not on β-blockers) were eligible for analysis. Among patients on β-blockers, propensity score matching was performed, and 218 patients on β1-selective blockers and 218 patients on nonselective β-blockers were studied. During a 2-year follow-up, patients on β1-selective blockers had significantly fewer major cardiac and cerebrovascular events (hazard ratio=0.62; 95% confidence interval=0.42-0.91; P=0.014), a trend toward lower all-cause mortality (hazard ratio=0.66; 95% confidence interval=0.38-1.14; P=0.135), and nonworsening liver outcome (hazard ratio=0.66; 95% confidence interval=0.38-1.14; P=0.354). Conclusions In patients with cirrhosis and acute myocardial infarction, selecting a β-blocker is a clinical dilemma. Our study showed that the use of β1-selective blockers is associated with lower risks of major cardiac and cerebrovascular events.

Project description:Liver cirrhotic predisposes patients to coagulopathy and bleeding. Little is known about outcomes of acute myocardial infarction (AMI) in cirrhotic patients.Data from Taiwan National Health Insurance Research Database during 2001 to 2013 were retrieved for patients admitted with cirrhosis and AMI. We excluded patients with missing information, <20 years old, previous AMI, previous coronary intervention, and liver transplant. Patients were separated into cirrhotic and non-cirrhotic. Primary outcomes included all-cause mortality, recurrent myocardial infarction (MI), major cardiac and cerebrovascular events (MACCE: recurrent MI, revascularization, ischemic stroke, and heart failure), and liver outcomes (hepatic encephalopathy, ascites tapping, spontaneous peritonitis, and esophageal varices bleeding).A total of 3217 cirrhotic patients and 6434 non-cirrhotic patients were analyzed, with a mean follow up of 2.8 ± 3.3 years. In cirrhotic patients with AMI, subsequent coronary and cerebrovascular events were lower in comparison to non-cirrhotic patients, with higher all-cause mortality observed from adverse liver related outcomes and bleeding. There were significantly lower cumulative incidence of both recurrent MI and MACCE in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (hazard ratio [HR] 0.82, confidence interval [CI] 0.71-0.94, P = .006 and HR 0.86, 95% CI 0.79-0.92, P < .001, respectively). There was significantly higher cumulative incidence of liver related outcome in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (HR 2.27, 95% CI 2.06-2.51, P < .001). And there was significantly higher all-cause mortality in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (HR 1.30, 95% CI 1.23-1.38, P < .001).In cirrhotic cohort with AMI, a decreased in coronary and cerebrovascular events were observed. However, these patients also had higher all-cause mortality due to adverse liver outcomes and bleeding.

Project description:The benefits and risks of prolonged dual antiplatelet therapy may be different for patients with acute myocardial infarction (MI) compared with more stable presentations.This study sought to assess the benefits and risks of 30 versus 12 months of dual antiplatelet therapy among patients undergoing coronary stent implantation with and without MI.The Dual Antiplatelet Therapy Study, a randomized double-blind, placebo-controlled trial, compared 30 versus 12 months of dual antiplatelet therapy after coronary stenting. The effect of continued thienopyridine on ischemic and bleeding events among patients initially presenting with versus without MI was assessed. The coprimary endpoints were definite or probable stent thrombosis and major adverse cardiovascular and cerebrovascular events (MACCE). The primary safety endpoint was GUSTO (Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Arteries) moderate or severe bleeding.Of 11,648 randomized patients (9,961 treated with drug-eluting stents, 1,687 with bare-metal stents), 30.7% presented with MI. Between 12 and 30 months, continued thienopyridine reduced stent thrombosis compared with placebo in patients with and without MI at presentation (MI group, 0.5% vs. 1.9%, p < 0.001; no MI group, 0.4% vs. 1.1%, p < 0.001; interaction p = 0.69). The reduction in MACCE for continued thienopyridine was greater for patients with MI (3.9% vs. 6.8%; p < 0.001) compared with those with no MI (4.4% vs. 5.3%; p = 0.08; interaction p = 0.03). In both groups, continued thienopyridine reduced MI (2.2% vs. 5.2%, p < 0.001 for MI; 2.1% vs. 3.5%, p < 0.001 for no MI; interaction p = 0.15) but increased bleeding (1.9% vs. 0.8%, p = 0.005 for MI; 2.6% vs. 1.7%, p = 0.007 for no MI; interaction p = 0.21).Compared with 12 months of therapy, 30 months of dual antiplatelet therapy reduced the risk of stent thrombosis and MI in patients with and without MI, and increased bleeding.
