Trends, outcomes, and management of acute myocardial infarction in patients with chronic viral hepatitis.

OBJECTIVES: There is a paucity of data on the management and outcomes of chronic viral hepatitis (CVH) patients [including chronic hepatitis B (CHB) and chronic hepatitis C (CHC)] presenting with acute myocardial infarction (AMI). METHODS: We utilized the National Inpatient Sample database (2001-2019) and studied the management and outcomes of CVH patients with AMI and stratified them by subtypes of CVH. The adjusted odds ratio (aOR) of adverse outcomes in CVH groups were compared to no-CVH groups using multivariable logistic regression. RESULTS: Of 18,794,686 AMI admissions, 84,147 (0.45%) had a CVH diagnosis. CVH patients had increased odds of adverse outcomes including in-hospital mortality (aOR 1.40, 95%CI 1.31-1.49, p < 0.05), respiratory failure (1.11, 95%CI 1.04-1.17, p < 0.001), vascular complications (1.09, 95%CI 1.04-1.15, p < 0.001), acute kidney injury (1.36, 95%CI 1.30-1.42, p < 0.001), gastrointestinal bleeding (1.57, 95%CI 1.50-1.68, p < 0.001), cardiogenic shock (1.44, 95%CI 1.04-1.30, p < 0.001), sepsis (1.24, 95%CI 1.17-1.31, p < 0.001), and were less likely to undergo invasive management. On subgroup analysis, CHB had higher odds of adverse outcomes than the CHC group (p < 0.05). CONCLUSION: CVH patients presenting with AMI are associated with worse clinical outcomes. CHB subgroup had worse outcomes compared to the CHC subgroup.

Low high-density lipoprotein cholesterol is associated with impaired endothelial function in Asian Indians.

This study was designed to assess the relationship between plasma lipid levels and endothelial function in Asian Indians without cardiovascular risk factors living in the United States. While traditional risk factors do not account for the increased incidence of coronary heart disease (CHD) in Asian Indians, low high-density lipoprotein (HDL) cholesterol, elevated triglycerides, elevated lipoprotein (a), and insulin resistance are consistently found in Asian Indians with CHD. Endothelial function was measured in 86 healthy Asian Indians (mean age 33 years) free of cardiac risk factors with LDL levels<160 mg/dL. Subjects were divided into two groups on the basis of HDL levels (low HDL<40 mg/dL and normal HDL-40 mg/dL). Endothelial function during reactive hyperemia was significantly impaired in Asian Indians in the low HDL group. After covariate adjustment, NTG-induced brachial vasodilation was not different between patients in the two HDL groups. These data indicate that low HDL is associated with endothelial dysfunction in this population.

Fingernail clubbing and chromonychia associated with the use of angiotensin II receptor blockers.

Fingernail clubbing and discoloration frequently indicate serious pulmonary, cardiovascular, and gastrointestinal pathologies. A 76-year-old Caucasian man developed clubbing of the fingernails and discoloration of both the fingernails and toenails after 27 days of treatment with the angiotensin II receptor blocker (ARB) losartan 50 mg/day. Even though this therapy was switched to valsartan, the nail changes persisted for another 6 months. The patient's therapy then was changed to captopril, and the changes gradually subsided over 17 months. An extensive literature search revealed no reports of this effect in association with ARBs. However, one manufacturer had received spontaneous reports. Despite careful consideration of other possible causes of the patient's symptoms, the temporal association with the start and discontinuation of ARB therapy suggests a possible drug-related adverse event.

Acute eosinophilic myocarditis mimicking myocardial infarction.

Eosinophilic myocarditis is characterized by progressive myocardial damage that results in heart failure and death. Herein, we present the case of a 54-year-old man who presented with symptoms of acute myocardial infarction. Normal coronary angiographic results and the presence of elevated levels of peripheral-blood eosinophilia prompted an endomyocardial biopsy that revealed acute eosinophilic myocarditis. The early initiation of steroid therapy resulted in the patient's substantial clinical improvement and survival. Early diagnosis of eosinophilic myocarditis and its treatment with steroid agents in some patients can lead to a favorable outcome. We discuss the challenge of diagnosing and identifying the characteristics of this variant of necrotizing eosinophilic myocarditis before the condition proves fatal.

Physician gender and patient care.

Since 1960, there has been a remarkable increase in the number of women graduating from United States medical schools. Concurrent with this increase, a large body of research has emerged on whether patient gender has an impact on disease diagnosis and therapy. From that research, a related question has emerged: Do patients receive different treatment based on the gender of their physician? In this article, we review the current literature regarding the effects of the gender of the primary care physician on patient care. Our purpose is to understand the potential implications of the changing demographics in the primary care specialties, and to propose a framework for further investigation.

ACE inhibitor-induced bronchial reactivity in patients with respiratory dysfunction.

BACKGROUND: Angiotensin-converting enzyme (ACE) inhibitors are often associated with an increased incidence of cough and bronchial responsiveness that may cause further deterioration of patients with impaired pulmonary function. OBJECTIVE: To review the available literature on the incidence of cough and bronchial responsiveness associated with ACE-inhibitor therapy in patients with asthma, chronic obstructive pulmonary disease (COPD), and congestive heart failure (CHF). DATA SOURCES: Literature was accessed through MEDLINE (1985-September 2001). Key search terms included cough, bronchospasm, asthma, congestive heart failure, chronic obstructive pulmonary disease, ACE inhibitors, and angiotensin II receptor blockers. DATA SYNTHESIS: The literature reports several cases of increased bronchial responsiveness associated with ACE inhibitors. Larger, controlled studies evaluating the increased risk in patients with pulmonary dysfunction are limited. Data from these trials are summarized in this article. CONCLUSIONS: The literature shows that patients with primary airway disease such as asthma and COPD are not at an increased risk of developing cough or bronchoconstriction as a result of ACE-inhibitor therapy. Despite the ability of ACE inhibitors to improve exercise tolerance, perfusion, and gas transfer, patients with CHF may be at higher risk of developing cough than the general population. Whether this cough is attributed to ACE inhibition or increased left-ventricular dysfunction remains uncertain. If increased bronchial responsiveness does occur, angiotensin II receptor antagonists are another reasonable option.
