Associations of Pentraxin 3 with cardiovascular disease: The Multi-Ethnic Study of Atherosclerosis.
By: Jenny NS, Blumenthal RS, Kronmal RA, Rotter JI, Siscovick DS, Psaty BM.
In a study of apparently healthy adults, Pentraxin 3 was associated with CVD risk factors, subclinical CVD, CAC and incident coronary heart disease events independent of C-reactive protein (CRP) and CVD risk factors. These results support the hypothesis that PTX3 reflects different aspects of inflammation than CRP and may provide additional insight into the development and progression of atherosclerosis.

Vascular disease patient information page: Peripheral artery disease.
By: Ratchford EV, Evans NS.

Peripheral artery disease is common, and the symptoms typically include leg discomfort with exercise. Patients with PAD can also have other symptoms such as non-healing wounds on the feet. A simple ABI test with a blood pressure cuff can diagnose PAD. Treatment for PAD includes smoking cessation, medications aimed at preventing heart attack and stroke, and exercise to alleviate the discomfort. Patients with more severe PAD, such as those with wounds that are not healing or those with symptoms that do not respond to medication and exercise, may need to undergo a procedure to restore blood flow to the leg (angioplasty or bypass surgery).

Vascular disease patient information page: Venous Thromboembolism (deep vein thrombosis and pulmonary embolism).
By: Evans NS, Ratchford EV.

Venous thromboembolism is common, occurring in about one to two per 1000 people each year. DVT is typically diagnosed using ultrasound. PE is usually diagnosed using a CT scan. Anticoagulant medications are the mainstay of treatment; most patients take anticoagulants for a minimum of 3 months. Several important measures can help prevent venous thromboembolism.
