TL;DR: Heart failure is a syndrome characterized by high mortality, frequent hospitalization, reduced quality of life, and a complex therapeutic regimen that makes HF an ideal candidate for practice guidelines.

TL;DR: There was no association between any single medication class and an increased likelihood of a positive test for Covid-19 or in the risk of severe Covd-19 among patients who tested positive in association with five common classes of antihypertensive medications.
Abstract: Background There is concern about the potential of an increased risk related to medications that act on the renin–angiotensin–aldosterone system in patients exposed to coronavirus disease ...

TL;DR: EPO significantly enhances exercise capacity in patients with chronic heart failure and one mechanism of improvement in &OV0312;o2 is increased oxygen delivery from increased hemoglobin concentration.
Abstract: Background— Patients with chronic heart failure (CHF) are frequently anemic. An increase in hemoglobin could enhance exercise performance by increasing oxygen delivery. We investigated the effect of erythropoietin (EPO) on exercise performance in anemic patients with CHF. Methods and Results— Twenty-six anemic patients aged 57±11 years were randomized to receive EPO (15 000 to 30 000 IU per week) or placebo for 3 months. Parameters measured at baseline and end therapy included blood parameters (hemoglobin, hematocrit, plasma volume), exercise parameters (peak oxygen consumption [Vo2], exercise duration, 6-minute walk), muscle aerobic metabolism (half-time of Vo2 and near infrared recovery), and forearm vasodilatory function. EPO was well tolerated by all patients. Twelve patients in the EPO group felt improvement versus 1 in the placebo group (P<0.05). There were significant increases in hemoglobin (11.0±0.5 to 14.3±1.0 g/dL, P<0.05), peak Vo2 (11.0±1.8 to 12.7±2.8 mL · min−1 · kg−1, P<0.05) and exerci...

TL;DR: In this paper, the prevalence of anemia and its effect on outcome was examined in 196 patients with chronic heart failure (CHF) and the authors found that 60% of the patients were anemic.
Abstract: Background— Anemia frequently occurs in chronic heart failure (CHF) patients and is associated with a poor prognosis. A low hematocrit may result from an increased plasma volume (hemodilution) or from reduced red blood cell volume (true anemia). The prevalence and clinical outcome of CHF patients with hemodilution is unknown. Methods and Results— The prevalence of anemia and its effect on outcome was examined in 196 patients with CHF. The prevalence of hemodilution was assessed in a subset of 37 ambulatory anemic patients with I131-tagged albumin to measure red blood cell and plasma volume. Clinical outcome was monitored. Sixty-one percent of the CHF patients were anemic. The prevalence of anemia increased from 33% in patients with New York Heart Association class II heart failure to 68% in class IV CHF patients. Survival was reduced in anemic patients compared with patients with a normal hematocrit (P<0.05). In the subset of 37 anemic patients, 17 patients (46%) had hemodilution and 20 patients (54%) had...

TL;DR: In this paper, the local vascular response to intraarterial infusions of graded concentrations of acetylcholine and nitroglycerin was studied in the superficial femoral artery of 19 patients with congestive heart failure (New York Heart Association classes I to IV) and 6 age-matched normal control subjects.

TL;DR: These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care.
Abstract: XI. STRATEGIES FOR IMPROVING DIABETES CARE D iabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. Diabetes care is complex and requires that many issues, beyond glycemic control, be addressed. A large body of evidence exists that supports a range of interventions to improve diabetes outcomes. These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care. While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided. These standards are not intended to preclude more extensive evaluation and management of the patient by other specialists as needed. For more detailed information, refer to Bode (Ed.): Medical Management of Type 1 Diabetes (1), Burant (Ed): Medical Management of Type 2 Diabetes (2), and Klingensmith (Ed): Intensive Diabetes Management (3). The recommendations included are diagnostic and therapeutic actions that are known or believed to favorably affect health outcomes of patients with diabetes. A grading system (Table 1), developed by the American Diabetes Association (ADA) and modeled after existing methods, was utilized to clarify and codify the evidence that forms the basis for the recommendations. The level of evidence that supports each recommendation is listed after each recommendation using the letters A, B, C, or E.
