Sleep is essential for maintaining good heart health, but the use of sleeping pills has been linked to an increased risk of cardiovascular events and poor outcomes in heart patients. Certain sleep medications, such as those containing melatonin, have been associated with ventricular arrhythmias, even in structurally normal hearts. Other drugs, like suvorexant, which is used to treat insomnia, may not directly increase heart rate, but their side effects, such as rapid transitions from wakefulness to sleep, can be dangerous. While these medications can help address sleep disorders, it is crucial to carefully consider their potential impact on heart health, especially in vulnerable patient groups.

Sleeping pills and heart failure patients
Sleep is an essential part of maintaining good heart health. However, certain sleep medications can have adverse effects on cardiovascular health, especially for those with pre-existing heart conditions.
Heart failure patients often experience sleeping problems, and it is common for them to be prescribed sleeping pills when they are discharged from the hospital. However, studies have shown that sleeping pills can dramatically increase the risk of cardiovascular events in these patients. Research presented at the Heart Failure Congress in 2014 found that sleeping pills increased the risk of cardiovascular events in heart failure patients by eightfold. This means that patients with heart failure who take sleeping pills are eight times more likely to be rehospitalized for heart failure or cardiovascular-related death than those who do not take sleeping pills.
Benzodiazepine hypnotics, a type of sleeping pill, may have cardiodepressant and respiratory depressant actions. These effects could exacerbate sleep disordered breathing in heart failure patients and lead to a worse prognosis. As such, patients with heart failure who take sleeping pills, especially those with sleep disordered breathing, should be carefully monitored.
It is important to note that the findings of the studies mentioned above need confirmation in larger, prospective studies before definitive conclusions can be made and guidelines changed. However, the current research highlights the potential risks associated with the use of sleeping pills in heart failure patients and underscores the importance of careful monitoring of these patients.
Melatonin and Cardiovascular Events
In addition to prescription sleeping pills, over-the-counter sleep medications containing melatonin have also been associated with potential cardiovascular risks. While melatonin is often expected to protect against arrhythmias due to its ability to alleviate sleep deprivation, there have been reports of melatonin inducing ventricular arrhythmias even in structurally normal hearts. Discontinuation of melatonin in these cases resolved the arrhythmias.
In conclusion, while sleeping pills can be beneficial for managing sleep disorders, they may also increase the risk of cardiovascular events, especially in individuals with heart failure. It is crucial for heart failure patients to consult with their healthcare providers before taking any sleep medications and to explore alternative solutions for insomnia, such as lifestyle changes and non-pharmacological treatments.

Benzodiazepine hypnotics and heart rate
Benzodiazepines are one of the most commonly prescribed hypnotics for patients with insomnia. They target the benzodiazepine sites of the γ-aminobutyric acid (GABA) type A (GABAA) receptors. While they are effective in treating insomnia, they have been associated with certain risks.
Several studies have investigated the impact of benzodiazepine hypnotics on heart rate. Sleep laboratory studies have shown that benzodiazepines administered orally as hypnotics can lead to an elevation in heart rate during sleep. This increase in heart rate can last for up to 4 hours. However, it is important to note that the cardiovascular effects of benzodiazepines administered intravenously as preoperative sedatives have been more extensively studied, and the focus on oral administration is relatively limited.
The findings suggest that the HR elevation may not be clinically significant for most patients. However, it does indicate that benzodiazepines administered at hypnotic-dose levels can have peripheral and central effects.
In addition to the impact on heart rate, benzodiazepines have been associated with adverse prognoses in heart failure patients with insomnia. Studies have shown that the use of benzodiazepines in this population is linked to a higher risk of rehospitalization for heart failure and an increased risk of cardiovascular events. The risk of cardiovascular events in heart failure patients taking sleeping pills was found to be eight times higher, specifically in HFpEF patients.
While these findings highlight potential concerns with the use of benzodiazepine hypnotics, it is important to note that larger and more comprehensive studies are needed to confirm these results. Additionally, the selection of hypnotics should be carefully considered, as certain alternatives, such as Z-drugs (zolpidem, zopiclone, and eszopiclone), may have different impacts on heart rate and prognosis in heart failure patients with insomnia.

Melatonin and structurally normal hearts
Melatonin is a pineal hormone that regulates the body's circadian rhythms and sleep-wake cycles. It is widely used as a prescription or over-the-counter drug to treat sleep disorders. Melatonin is also not controlled by the Food and Drug Administration (FDA), so there may be concerns about the dosage of melatonin in dietary supplements.
Several studies have found that melatonin can induce ventricular arrhythmias in structurally normal hearts. One study found that melatonin use was associated with symptomatic premature ventricular contractions (PVCs) in two patients with structurally normal hearts. Another study found that a 37-year-old male patient with hypertension experienced right ventricular conduction delay after taking 43, 10 mg melatonin pills and binge drinking. The patient's ECG showed a "saddleback" appearance, which returned to normal after a few hours.
However, other studies have argued that melatonin has a protective effect against arrhythmias. One study found that melatonin increased the repetitive extrasystole threshold of the vulnerable period of the ventricular myocardium, arguing for a protective effect against arrhythmias. Another study found that melatonin has antiarrhythmic and antioxidant benefits, which could make it a "fountain of youth" for the heart.
While the evidence is mixed, the potential association between melatonin use and ventricular arrhythmias in structurally normal hearts highlights the importance of identifying precipitating factors for idiopathic ventricular arrhythmias (IVAs).

Suvorexant and heart rate
Orexins are neuropeptides that play a role in regulating the sleep-wake cycle by maintaining wakefulness. They also contribute to the central regulation of cardiovascular function and have been shown to increase blood pressure and heart rate in animal models. Suvorexant is a highly selective, reversible dual orexin receptor antagonist that blocks the binding of orexin A and orexin B to orexin receptor types 1 and 2, respectively. By blocking the activity of orexins, suvorexant reduces arousal and wakefulness, promoting sleep.
Suvorexant is a sedative medication used to treat insomnia, specifically for those who have difficulty falling and/or staying asleep. It is available under the brand name Belsomra, with a recommended starting dose of 10 mg taken orally no more than once per night and within 30 minutes of going to bed. Suvorexant is considered safe for adult patients, but its safety and efficacy for pediatric patients have not been established.
While suvorexant can be effective in treating insomnia, it does come with certain side effects. Common side effects include drowsiness, headache, dizziness, abnormal dreams, upper respiratory tract infections, cough, diarrhea, and dry mouth. Additionally, post-marketing side effects have been reported, including palpitations, fast heart rate, psychomotor hyperactivity, and anxiety. It is important to consult a doctor before taking suvorexant, as it can interact with other medications and may not be suitable for everyone.
The SUPER-1 study investigated the effects of suvorexant on nighttime blood pressure in patients with insomnia and hypertension. The study found a slight decrease in nighttime systolic blood pressure from baseline to week 2 in both the suvorexant and placebo groups, with a slightly greater decrease in the suvorexant group. However, the difference between the groups was not statistically significant.
In summary, suvorexant is a sedative medication that can effectively treat insomnia by blocking orexin receptors and reducing arousal and wakefulness. While it may improve sleep, suvorexant can also cause side effects, including an increased heart rate and other cardiovascular effects. It is important to carefully consider the potential benefits and risks before taking suvorexant and to consult a healthcare professional for personalized advice and monitoring.

Poor sleep and heart health
Sleep is an essential component of good heart health. Sleep disorders and poor sleep quality can negatively affect cardiovascular health in several ways. Firstly, sleep deprivation can lead to higher-than-average blood pressure levels, which is a major risk factor for heart disease. Research has also found a link between lack of sleep and elevated nighttime blood pressure, which is an even stronger predictor of heart problems than high blood pressure during the day. Sleep deprivation can also cause metabolic changes, upsetting the balance of appetite-regulating hormones and leading to weight gain, which is another risk factor for heart disease.
Poor sleep is associated with prediabetes and glucose intolerance, as it worsens glucose metabolism. Excess blood glucose damages blood vessels, negatively impacting cardiovascular health. People with diabetes are twice as likely to die from heart disease or stroke than those without the condition. Poor sleep can also cause inflammation, which contributes to atherosclerosis, a condition where plaque builds up in the arteries, narrowing them and reducing blood and oxygen flow to the heart.
Sleep disorders such as insomnia, apnea, narcolepsy, and restless leg syndrome have been linked to a higher risk of cardiovascular disease. Sleep apnea, in particular, is a common and underdiagnosed condition where breathing is interrupted during sleep, which can activate cardiac arrhythmias and elevate blood pressure. Even a one-hour shift in sleep, such as during daylight savings time, can negatively affect heart health, with studies showing an increased risk of heart attacks during these times.
While sleeping pills have been shown to increase the risk of cardiovascular events in heart failure patients, melatonin has been proposed to have a protective effect against arrhythmias. However, there are concerns about the lack of control over the melatonin content in dietary supplements, and some studies have found that melatonin can induce ventricular arrhythmias even in structurally normal hearts. Overall, getting enough quality sleep is crucial for maintaining good heart health, and exercise, meditation, and other behavioral changes can help reduce the risk of both sleep deprivation and heart problems.
