Your Question

I survived an episode of acute thrombotic thrombocytopenic purpura. I have since developed heart problems and tremors. Can thrombotic thrombocytopenic purpura cause heart and other chronic health problems? 

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

Can thrombotic thrombocytopenic purpura cause heart and other chronic health problems?

Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that causes blood clots (thrombi) to form in small blood vessels throughout the body.[1] These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart. Resulting complications can include neurological problems (such as personality changes, headaches, confusion, and slurred speech), fever, abnormal kidney function, abdominal pain, and heart problems.[1] TTP can casue a variety of heart problems, including heart attack, arrhythmia, and congestive heart failure.[1][2][3]. Treatment of TTP with plasma exchange has greatly improved the chance of recovery from acute episodes of TTP.[3] 

Information regarding the long term health consequences of TTP is lacking, however the following recent articles explore this topic further and may be a helpful resource. These articles suggest that people with a history of TTP may be at an increased risk for long term neurological, kidney, blood vessel, and heart complications.

You can search for further relevant journal articles on TTP and chronic health problems through a service called PubMed. PubMed is a searchable database of medical literature. Click here to view a sample search.

Not all the articles in PubMed are available for free online. To obtain the full article, contact a medical/university library (or your local library for interlibrary loan), or order it online through the publisher's Web site. The National Library of Medicine has a Web page for locating libraries in your area that can provide direct access to journals (print or online). You can access this page at the following link.

Are there research studies or clinical trials enrolling people with thrombotic thrombocytopenic purpura?

There is a research consortium called, The Rare Thrombotic Diseases Consortium (RTDC), which is investigating TTP.  The Rare Thrombotic Diseases Consortium aims to improve the lives of people with antiphospholipid antibody syndromes, heparin-induced thrombocytopenia, paroxysmal nocturnal hemoglobinuria, catastrophic antiphospholipid antibody syndrome (thrombotic storm), and thrombotic thrombocytopenic purpura (TTP) through research.

The U.S. National Institutes of Health, through the National Library of Medicine, developed ClinicalTrials.gov to provide patients, family members, and members of the public with current information on clinical research studies. Currently, clinical trials are identified as enrolling individuals with thrombotic thrombocytopenic purpura. To find these trials, visit the link below and use 'thrombotic thrombocytopenic purpura' as your search term. After you click on a study, review its 'eligibility' criteria to determine its appropriateness. Use the study’s contact information to learn more. Check this site often for regular updates.
