Poor blood circulation is a serious health concern. Conditions that compromise the flow of blood throughout the body can be life-threatening. Arties that become thick and lose their flexibility results in arteriosclerosis. This impedes the flow of blood within the body and can lead to peripheral arterial disease (PAD). If this condition becomes severe enough, tissue death can occur which could require amputation of an extremity. Individuals with PAD are also at a higher risk for heart attacks and strokes. Coronary artery disease (CAD) is a condition that results from narrowing of the coronary arteries that slows critical blood flow to the heart. One out of five deaths in the U.S. is caused by CAD.
Blood clots can block the flow of blood to the heart or brain. These blood clots can result in death due to a stroke or heart attack. Weakened blood vessels that burst are known as aneurysms. Aneurysms result in internal bleeding that can be fatal. Anti-coagulants such as dabigatran have been prescribed to fight acute coronary syndrome.
There have been several recent innovations in medical technology that are offering promising new diagnostic tools and treatment options for these diseases related to poor blood circulation. The Heart & Vascular Center of Arizona just announced that it will be offering a gene expression test that can predict the likelihood of patients developing CAD. This test which involves a blood draw will allow physicians to offer individualized patient care while giving them a complete picture of their patient’s disease.
The FDA recently approved a new device for the treatment of PAD. This device is called the Wildcat Guidewire Support Catheter. The Wildcat Catheter opens up arteries that are difficult to treat or even completely blocked. The catheter is primarily, at this point, used to treat arteries in the thighs but may eventually be used to treat smaller arteries below the knee or in the heart.
The Siemens Definition Flash CT offers a new innovation in imaging technology that delivers clear pictures of the heart in just 250 milliseconds. This lightning speed means that patients are exposed to the lowest dose of radiation. The speed of the imaging technology also eliminates the need to slow patents’ heartbeats with beta-blockers to obtain adequate high-quality images.
Another innovation in imaging technology has been cleared by the FDA. The imaging service is called 3D Recon. It converts two-dimensional clinical images to three-dimensional images. Bone and anatomy are removed so that surgeons can better visualize the interior of a patient’s vein before surgery. 3D Recon also enables surgeons to better assess stent grafts following implantation.
