Antihypertensive Drugs: Vasodilators

Antihypertensive Drugs: Vasodilators

Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...

Acute Inflammation III: Local and Systemic Effects

Acute Inflammation III: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...

Autoregulation of Blood Flow

Autoregulation of Blood Flow

Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation.

Summary

This summary is machine-generated.

Cold-induced vasodilation (CIVD) involves repeated warming of fingers during cold exposure. This meta-analysis found CIVD onset averages 7.9 minutes, influenced by factors like immersion area, sex, age, and ambient temperature.

Background:

Cold-induced vasodilation (CIVD) is a physiological response to cold exposure, characterized by intermittent blood flow to extremities.
Despite extensive research, a comprehensive synthesis of CIVD factors and mechanisms is lacking.

Purpose of the Study:

To conduct a meta-analysis and narrative review to synthesize existing research on cold-induced vasodilation.
To identify factors influencing CIVD onset and magnitude and to explore underlying physiological mechanisms.

Main Methods:

Meta-analysis of 80 studies involving hand immersion in cold water (<20°C) for 30 minutes.
Narrative literature review of individual factors and proposed CIVD mechanisms.

Main Results:

The weighted average onset time for CIVD was 7.9 minutes, with mean finger temperature at 10.0°C.
CIVD onset was longer for whole-hand immersion, larger body surface area, and males; it was shorter with higher ambient temperatures, in cold-adapted populations, and with increasing age.
Onset time showed a weak negative correlation with finger temperature during immersion.

Conclusions:

CIVD onset is primarily triggered by local tissue temperature, while its magnitude depends on sympathetic activity.
Proposed mechanisms involve impaired noradrenaline transfer or nitric oxide release, requiring further investigation.
Future research should include more females and older adults due to their underrepresentation.
