Conditions Associated at Death with Specific Types of Completed Stroke in Patients with and without Hypertension: A Case-Control Study

Abstract

Potential risk factors for various types of stroke were studied using a case-control study design. All 1978 US death certificates for which the registered underlying cause of death was subarachnoid hemorrhage (SAH), cerebral hemorrhage (CH), or cerebral infarction (CI) were identified. The frequency with which other conditions appeared on the death certificates of cases with and without hypertension was compared with controls. These data provide new information, such as the occurrence of peripheral vascular disease in association with SAH, the risk of CH in epileptic and cirrhotic patients, and the association of benign neoplasms of the nervous system, motor neuron disease, and ''paralysis agitans'' with CI.

“…Fillers are also used to reduce cost or to impart certain characteristics such as modulus, abrasion resistance, tear resistance, and tensile strength. [1][2][3] Another consequence of incorporating a filler into a polymer is the considerable change in the dynamic properties one can achieve in the final composites. 4 Carbon black is unquestionably the universal reinforcing filler, even though silicas are also often used.…”
