Psilocybin mushrooms may cause tachycardia and arrhythmias
Psilocybin mushrooms, commonly known as "magic mushrooms", have been used since ancient times for their mind-altering and healing properties. While they are generally considered to have a low side-effect profile and low toxicity, with most side effects being benign and self-limiting, there have been rare cases of more severe clinical effects, including cardiac arrest.
The hallucinogenic effects of psilocybin mushrooms are believed to occur through stimulation of serotonin receptors, specifically 5-HT2A-serotonin receptors in the brain. Serotonin also plays a crucial role in regulating heart function, and it is thought that the activation of these receptors by psilocybin may lead to an increased force of contraction and beating rate, resulting in tachycardia and arrhythmias.
In addition, psilocybin mushrooms may also increase blood pressure, which, when combined with the increased heart rate, can further strain the cardiovascular system. This increase in blood pressure and heart rate may present a risk to individuals with existing cardiovascular illnesses or risk factors, such as heart failure or a family history of cardiac issues.
While the exact mechanism behind these cardiac effects is not yet fully understood, some studies suggest that the proarrhythmic effects of psilocybin may be due, in part, to their cyclic adenosine monophosphate (cAMP)-increasing effects on the heart. Furthermore, chronic use of psilocybin mushrooms may also increase the risk of valvular heart disease (VHD) and cardiac fibrosis due to their structural similarities with medications known to cause these conditions.

The mushrooms have been linked to cardiac arrest in some cases
Psilocybin mushrooms, also known as "magic mushrooms", have been used since ancient times for their mind-altering and medicinal properties. They contain the active compound psilocybin, which has hallucinogenic and antidepressant effects. While these mushrooms are generally considered to have a low toxicity profile, there have been rare cases of serious adverse events associated with their use, including cardiac arrest.
The mechanism behind the potential cardiovascular effects of psilocybin mushrooms involves their action on serotonin receptors in the heart, particularly the 5-HT4 subtype. This action can lead to increased contractility and heart rate, known as positive inotropic and chronotropic effects, respectively. These effects have been observed in both animal and human studies, indicating that psilocybin mushrooms can indeed influence heart function.
The case reports of cardiac arrest associated with psilocybin mushroom use are particularly concerning. In one reported incident, a 48-year-old male with a history of attention-deficit/hyperactivity disorder experienced a syncopal episode and was found to be in ventricular fibrillation. Another case involved a 17-year-old male who presented with chest pain and dyspnea, with initial workup showing widespread ST elevations and right bundle branch block on EKG. These cases underscore the potential seriousness of the cardiac side effects of psilocybin mushrooms.
It is important to note that the risk of cardiac complications may be higher in individuals with certain underlying conditions or risk factors. For example, in the aforementioned cases, the 48-year-old male had a history of ADHD, and his family history included multiple first-degree relatives with sudden cardiac death. Additionally, psilocybin mushrooms may pose a risk for individuals with cardiovascular illnesses such as heart failure, as the increase in heart rate and blood pressure associated with mushroom use could exacerbate existing cardiac issues.
While the exact incidence and mechanisms of psilocybin mushroom-induced cardiac arrest require further investigation, the existing evidence suggests that these mushrooms can have significant cardiovascular effects. Therefore, it is crucial for individuals considering their use, especially those with cardiovascular risk factors or conditions, to exercise caution and consult with healthcare professionals to weigh the potential benefits against the risks.

They can increase blood pressure and heart rate
Psilocybin mushrooms, also known as "magic mushrooms", have been used since ancient times for their mind-altering and healing properties. In recent years, there has been a resurgence in the use of psilocybin, particularly among terminally ill cancer patients and people suffering from depression. While psilocybin has been studied for its potential therapeutic benefits, including its antidepressant properties and relatively benign side effects, it is important to understand its effects on the heart.
Psilocybin mushrooms can indeed increase blood pressure and heart rate. Several studies have reported transient increases in systolic blood pressure and heart rate among individuals who have consumed psilocybin. These cardiovascular effects may be due to the activation of serotonin receptors, particularly the 5-HT4 receptor. The stimulation of these receptors can lead to increased force of contraction and an elevated heart beating rate. This positive inotropic effect has been observed in isolated human atrial preparations treated with psilocybin and its metabolite, psilocin.
The increase in blood pressure and heart rate may pose a risk to individuals with pre-existing cardiovascular conditions. For example, individuals with heart failure or other forms of cardiovascular disease may be at a higher risk of adverse events due to the cardiovascular effects of psilocybin mushrooms. Additionally, there have been rare reports of more serious complications associated with psilocybin use, including cardiac arrest and acute kidney injury.
While psilocybin mushrooms have a relatively low toxicity profile compared to other hallucinogenic substances, it is crucial to consider the potential risks, especially for individuals with cardiovascular concerns. The interaction between psilocybin and the cardiovascular system is complex and requires further research to fully understand its short-term and long-term effects. As with any substance, it is important to use psilocybin mushrooms with caution and under the guidance of medical professionals, especially for individuals with underlying health conditions.

The mushrooms may increase the risk of valvular heart disease
Psilocybin mushrooms, commonly known as "magic mushrooms", have been used since ancient times for their mind-altering and healing properties. While these mushrooms have gained popularity for their therapeutic potential, particularly in treating depression and improving quality of life, concerns have been raised about their impact on cardiovascular health.
One of the primary concerns regarding the consumption of psilocybin mushrooms is their potential effect on the human heart. Studies have shown that psilocybin can increase blood pressure and heart rate, which may present a risk to individuals with pre-existing cardiovascular conditions. This increase in blood pressure and heart rate is attributed to the stimulation of serotonin receptors, particularly the 5-HT2A and 5-HT4 subtypes. The activation of these receptors can lead to an increased force of contraction and beating rate, possibly resulting in arrhythmias.
While psilocybin mushrooms are generally considered to have a low side-effect profile and low toxicity, recent literature has associated their use with more serious adverse events. Case reports have linked psilocybin consumption to acute kidney injury and, notably, cardiac arrest. Additionally, there have been reports suggesting psilocybin as a potential trigger for Takotsubo Cardiomyopathy (TTC). These cases highlight the potential risks associated with psilocybin mushroom consumption, particularly for individuals with underlying cardiovascular vulnerabilities.
Furthermore, the chronic use of psilocybin mushrooms, especially in the form of microdosing, has raised concerns about the risk of valvular heart disease (VHD). Structural similarities have been observed between psilocybin and LSD, and certain medications known to increase the risk of cardiac fibrosis and valvulopathy, such as methysergide, pergolide, and fenfluramine. While clinical trials with psilocybin in the form of microdosing have not provided conclusive evidence, the potential risks of valvular heart disease due to prolonged use cannot be overlooked.

They are being studied for their antidepressant properties
Psilocybin, a compound found in magic mushrooms, has been studied for its potential as an alternative to traditional antidepressant therapies. It has been used since ancient times for its mind-healing properties and is known to induce a temporary increase in heart rate and blood pressure.
The use of psychedelics like LSD, ecstasy, and psilocybin-containing mushrooms has increased significantly in recent decades, especially among adolescents and young adults. Psilocybin acts on the 5-HT4 serotonin receptor, leading to higher force generation and an elevated heart beating rate. In healthy volunteers, hallucinogenic doses of psilocybin increased blood pressure.
Recent studies have compared the antidepressant effects of psilocybin with those of escitalopram, a traditional antidepressant. Results showed similar efficacy in treating depression, with psilocybin exhibiting a milder side effect profile. However, it is important to note that psilocybin use has been associated with more serious adverse events in some case reports, including acute kidney injury and cardiac arrest.
While psilocybin has shown promise in the treatment of depression, its safety in cardiovascular disease conditions is not yet fully understood. Some studies suggest that psilocybin-containing mushroom extracts may have beneficial effects on the heart, reducing the size of cardiomyoblasts, increasing mitochondrial activity, and reducing TNF-α and oxygen-free radical levels. However, other studies have reported that psilocybin might increase the force of contraction and beating rate, leading to arrhythmias.
Overall, while psilocybin mushrooms are being studied for their potential antidepressant properties, further rigorous placebo-controlled clinical trials are needed to fully understand their effects on the heart and establish their safety, especially for individuals with cardiovascular illnesses.
