T46: Poisoning by agents primarily affecting the cardiovascular system

The group of conditions classified under "Poisoning by agents primarily affecting the cardiovascular system" refers to medical situations where substances known to affect the heart and blood vessels are ingested, inhaled, injected, or otherwise introduced into the body. These substances could range from certain medications, recreational drugs, or specific toxins. They function by disrupting the cardiovascular system leading to various symptoms such as chest pain, irregular heart rate, shortness of breath, fainting episodes, or even cardiac arrest. These are emergent, life-threatening conditions that can progress rapidly if left untreated. Disease progression and severity depend on various factors such as the type and quantity of the agent, the person's underlying health condition, and the time elapsed since exposure to the agent. Immediate diagnosis and intervention are crucial in managing these conditions effectively.
