Cardiac manifestations of COVID-19.

COVID-19 is a novel viral infection caused by severe acute respiratory syndrome (SARS) beta-coronavirus. Epidemiological status changes dynamically as the pandemy is far from ending. Several complications of presented virus may be similar to those observed in other viral infections.

Annual prognostic factors in chronic heart failure in patients over 80 years old.

Background: In the elderly the most common cause of hospitalisation and the leading cause of death is heart failure (HF).

Aim: The purpose was to determine prognostic factors in chronic HF (CHF) in octogenarians and nonagenarians.

Methods: The analysis included 197 consecutive patients over 80 years old (mean age 83.

Factors affecting the quality of anticoagulation with warfarin: experience of one cardiac centre.

Introduction: The risk of complications in anticoagulation therapy can be reduced by maximising the percentage of time spent by the patient in the optimal therapeutic range (TTR). However, little is known about the predictors of anticoagulation control. The aim of this paper was to assess the quality of anticoagulant therapy in patients on warfarin and to identify the factors affecting its deterioration.

New oral anticoagulants - a practical guide.

Oral direct inhibitors of thrombin and activated factor Xa are approved as new anticoagulant drugs. In contrast to vitamin K antagonists (VKA) and heparins, the new agents have single targets in the coagulation cascade and more predictable pharmacokinetics, but they lack validated and available antidotes. Unlike VKA, they do not require routine monitoring of coagulation.

The impact of chronic kidney disease on the annual prognosis in patients 80+ years old suffering from chronic heart failure.

Introduction: It is well known that the function of kidneys is impaired with age.

Aim: The purpose of the study was to evaluate whether chronic kidney disease (CKD) is a predictor for 1-year follow-up mortality among hospitalized chronic heart failure (CHF) patients aged 80+.

Material And Methods: The study included 141 consecutive patients aged 80-92 (mean: 82.

Atrial fibrillation and prognosis in patients 80+ years old with chronic heart failure.

Introduction: It is well known that the prevalence of atrial fibrillation (AF) increases with age. The purpose was to evaluate the impact of AF at the 1-year outcome of patients aged 80? who suffered from chronic heart failure (CHF).

Materials And Methods: The study included 220 consecutive patients at age 80–92 (mean 82.
