Risk calculators and risk factors for Congestive heart failure and thrombosis

Overview[edit | edit source]

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.

Historical Perspective[edit | edit source]

Throughout history many renowned researchers and health care professionals have contributed to the understanding, definition, and recognition of thrombosis in Heart Failure patients.[1] [2] [3]

Year Event
1628 William Harvey describes the circulation.
1785 William Withering publishes an account of medical use of digitalis.
1920 Organomercurial diuretics are first used.
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. In 1987, the landmark CONSENSUS-I study showed the unequivocal survival benefits of enalapril in patients with severe heart failure.
2000- Role of Aspirin in heart failure patients is studied.

Pathophysiology[edit | edit source]

Stagnation of blood flow, disorder in vascular wall, and blood coagulation system are known factors that participate in the thrombosis formation, and its evident that Heart failure is often accompanied by hypercoaguble state[4] [5] [6].

 
 
 
 
Thrombus formation
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Abnormal blood flow (Blood Stasis)
 
Abnormal blood constituents
 
Abnormal blood vessel wall
 


In Heart failure, several factors come into play,

  • Firstly
    • Akinetic ventricular segments
    • Dilated ventricular chambers,
    • Dilated atria

with stagnant flow may increase thrombus formation[7].

  • Secondly endothelial dysfunction which occur in heart failure, may impair the antithrombotic function of the endothelium[8].

The prothrombotic stage[9] is further enhanced by

Epidemiology[edit | edit source]

Heart failure is the most frequent cause of hospitalization in patient aged 65 and above.[10] Heart failure is one of the most important public health problems, affecting an approximate half million patients in United States, with more than 550,000 new cases each year, and many more worldwide[11][4].

The incidence is expected to increase further in the next two decade as more number of people are surviving after myocardial infarction[12].

Natural History, Complications & Prognosis[edit | edit source]

Death is the ultimate complication that can happen in heart failure patients having thrombosis. In the ATLAS (Assessment of Treatment with Lisinopril and Survival) trial[13], there were many Heart failure patients who underwent autopsy, providing an unique opportunity and answering many questions about the cause of death.

Various trials have been conducted to suggest surrogate markers of heart failure.

Cause of death in autopsied Heart failure patients: ATLAS Trial[edit | edit source]

[13]

Condition Percentage (%)
No specific pathology (presumed arrhythmic death) 50.6
Myocardial infarction 42.1
Other Cardiovascular cause 4.8
Non-cardiac 2.4

Cause of death in Heart failure: SOLVD Trial[edit | edit source]

[14]

Condition Percentage (%)
Pump failure 49
Sudden death 23
Myocardial infarction 12
Non-cardiac 13
Fatal stroke or Pulmonary embolism 3*

Other Trials[edit | edit source]

  • The Warfarin and Antiplatelet Therapy in Chronic Heart Failure (WATCH[22]) 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[23]) 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[24]) Trial,which enrolled patients with left ventricular dysfunction after MI, the VTE annual rate (fatal and nofatal stroke) was 1.5%.

Current Guidelines[edit | edit source]

European Society of Cardiology[11][edit | edit source]

  • 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[25][edit | edit source]

  • 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.
  • 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.
