Background:
Over the past decades, the decline in mortality from stroke has been more pronounced in high-income countries than in low- and middle-income countries. We evaluated changes in temporal stroke mortality trends in Mexico according to sex and type of stroke.
Methods:
We assessed stroke mortality from Mexico's National Health Information System for the period from 1980 to 2012. We analyzed age-adjusted mortality rates by sex, type of stroke, and age group. The annual percentage change and the average annual percentage change (AAPC) in the slopes of the age-adjusted mortality trends were determined using joinpoint regression models.
Results:
The age-adjusted mortality rates due to stroke decreased between 1980 and 2012, from 44.55 to 33.47 per 100,000 inhabitants, and the AAPC (95% confidence interval [CI]) was -.9 (-1.0 to -.7). The AAPC for females was -1.1 (-1.5 to -.7) and that for males was -.7 (-.9 to -.6). People older than 65 years showed the highest mortality throughout the period. Between 1980 and 2012, the AAPC (95% CI) for ischemic stroke was -3.8 (-4.8 to -2.8) and was -.5 (-.8 to -.2) for hemorrhagic stroke. For the same period, the AAPC for intracerebral hemorrhage (ICH) was -.7 (-1.6 to .2) and that for subarachnoid hemorrhage (SAH) was 1.6 (.4-2.8).
Conclusions:
The age-adjusted mortality rates of all strokes combined, ischemic stroke, hemorrhagic stroke, and ICH, decreased between 1980 and 2012 in Mexico. However, the increase in SAH mortality makes it necessary to explore the risk factors and clinical management of this type of stroke.

Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
