Intracoronary acetylcholine testing has been established for the assessment of epicardial coronary spasm more than 30 years ago. Recently, the focus has shifted towards the microcirculation and it has been shown that microvascular spasm can be detected using ACH-testing. This article describes the ACH-test and its implementation in daily routine.

This protocol presents the acetylcholine rechallenge after nitroglycerine as an add-on procedure to spasm provocation testing. The purpose of this technique is to unmask co-existing microvascular spasm in patients with epicardial spasm and to assess the protective efficacy of nitroglycerine on a per-patient level to guide medical therapy.

Coronary vasomotion disorders represent frequent functional causes of angina in patients with unobstructed coronaries. The underlying mechanism of angina (endotype) in these patients can be determined by a comprehensive invasive diagnostic procedure based on acetylcholine provocation testing followed by Doppler-derived assessment of the coronary flow reserve and microvascular resistance.
FAQs
The receptor class engaged helps shape the downstream immune response. Acetylcholine signaling through muscarinic or nicotinic receptors can modify intracellular signaling, which in turn affects cytokine production, immune-cell activation, and inflammation. This receptor-dependent organization provides a framework for explaining why neural input can produce different effects in immune tissues.
Muscarinic and nicotinic receptors are relevant because they connect the same signaling molecule to potentially different cellular responses. The available information distinguishes these receptor families but does not assign one universal inflammatory outcome to each. Instead, their engagement is examined through changes in cytokine release, cell activation, and overall inflammatory behavior.
Stimulation of the α7 nicotinic receptor is associated with reduced release of several pro-inflammatory cytokines. That relationship makes α7 a useful focus for studying how cholinergic signals may restrain excessive immune activation. In infection and inflammation research, it helps connect receptor activity with measurable changes in host inflammatory responses.
Studies of this pathway can compare receptor stimulation with immune readouts such as cytokine production, cell activation, and inflammatory responses. These measurements allow investigators to relate cholinergic signaling to functional immune outcomes rather than to neural activity alone. In immunology, that comparison helps clarify how host defense and tissue inflammation are regulated.
It offers a way to examine how neural signals influence inflammatory activity during host defense. Because acetylcholine-related signaling can affect cytokine production and immune-cell activation, researchers can use this framework to study inflammation associated with infection and sepsis. The goal is to understand immune regulation, not simply to catalog receptor presence.
In autoimmune disease research, the pathway provides a context for examining excessive or misdirected immune activation. Its therapeutic relevance comes from the possibility of modulating cholinergic signaling to influence inflammatory responses. Findings involving receptor activity, cytokine release, and cell activation may therefore support investigation of approaches designed to reduce harmful immune activation.
