Overview
Heart failure is one of the most important public health problems, afflicting an approximate half million patients in United States, with more than 550,000 new cases each year, and many more worldwide[1][2]. CHF results when heart is not able to meet the demands of circulation causing insufficient blood flow. These patients are at higher risk of arterial and venous thrombosis.
Cause of death in Heart failure
Condition | Percentage (%) |
---|---|
Pump failure | 49 |
Sudden death | 23 |
Myocardial infarction | 12 |
Non-cardiac | 13 |
Fatal stroke or Pulmonary embolism | 3 |
Historical Perspective
Throughout history many renowned researchers and health care professionals have contributed to the understanding, definition, and recognition of thrombosis in Heart Failure patients.[3] [4] [5]
Year | Event |
1950s | Prognosis appeared better in Anticoagulated patient. |
1960s - 1970s | Retrospective analysis and Autopsy findings showed thromboembolism as an etiology. |
1980s - 1990s | Better understanding of hypercoaugubilty in Heart failure patients. |
2000- | Role of Aspirin in heart failure patients is studied. |
Pathophysiology
Stagnation of blood flow, disorder in vascular wall, and blood coagulation system are known factors that participate in the thrombosis formation.

Treatment
Rationale for Antithrombotic therapy in Heart failure
- Prevention of Stroke[6],
- Prevention of Systemic or Pulmonary embolism,
- Prevention of coronary thrombosis,
- Retarding progression of Heart failure.
- Increase survival.
Supportive Trial Data
- The Warfarin and Antiplatelet Therapy in Chronic Heart Failure (WATCH[7]) trial was the first modern RCT to study warfarin in patients with heart failure. The trial showed a reduction of nonfatal stroke events with warfarin over aspirin or clopidogrel.
- In the ARixtra for ThromboEMbolISm prevention in a medical indications study (ARTEMIS[8]) trial in acutely ill medical patients, fondaparinux significantly reduced the risk of total venous thromboembolism, without increasing bleeding risk compared with placebo.
- In the Survival and Ventricular Enlargement (SAVE[9]) Trial,which enrolled patients with left ventricular dysfunction after MI, the VTE annual rate (fatal and nofatal stroke) was 1.5%.
Current Guidelines
European Society of Cardiology[1]
- Anticoagulants have shown to be more effective than antiplatelet agents in reducing the risk of stroke; thus they are preferred agents in
- patients with more than one risk factors, like
- In patients with Heart failure and Atrial fibrillation lacking any other additional risk factors., to prevent primary VTE event.
- With respect to Antiplatelet agents,
- They are found to be less efficacious than anticougulants, in preventing a VTE event in patients with Atrial fibrillation, .
- Hospitalization for heart failure was significantly greater in aspirin-treated patients than in warfarin-treated patients.
ACC/AHA[10]
- Anticoagulants should be considered in
- Patients with heart failure having prior history of VTE.
- Patients having paroxysmal or persistant Atrial fibrillation.
- Patients with other co-morbidity, which increases the risk for VTE.
- Patients with familial dilated cardiomyopathy and a history of VTE in first-degree relatives.
- With respect to Antiplatelet agents, it should be used in:
- Myocardial infarction.
- Heart failure patients with known history of coronary artery disease.
- However, ACC/AHA has stated that
- Role of aspirin in heart failure is still not established.
- Aspirin may attenuate the hemodynamic and survival benefits of ACE inhibitors.
