Original Abstract of the Article

Major Research Findings

The studies 1 , 4 , 2 and 3 investigate the cardiovascular effects of various antidepressants, including amitriptyline, femoxetine, mianserin, and trazodone. 1 found that femoxetine and amitriptyline significantly affected systolic time intervals and electrocardiograms compared to placebo. Femoxetine reduced the QS2 index more than amitriptyline, while amitriptyline increased the PEP/LVET ratio and QRS duration. These findings suggest that femoxetine and, to a lesser extent, amitriptyline enhance contractility compared to placebo, and amitriptyline, but not femoxetine, delays intracardiac conduction. 4 reported that mianserin did not show significant adverse cardiovascular effects compared to amitriptyline. 3 indicated that trazodone had significantly fewer cardiovascular effects than amitriptyline, lacking the typical quinidine-like effect observed with amitriptyline. However, trazodone showed minor effects on heart rate and T wave changes. 2 examined the interaction of alcohol with amitriptyline and fluoxetine. The study revealed that amitriptyline had a stronger interaction with alcohol than fluoxetine, resulting in more pronounced subjective effects.

Benefits and Risks

Benefit Summary

These studies suggest that femoxetine and mianserin might have fewer significant adverse cardiovascular effects compared to amitriptyline. Trazodone also demonstrated significantly fewer cardiovascular effects compared to amitriptyline. These medications have the potential to enhance contractility and improve heart function.

Risk Summary

Amitriptyline can affect the cardiovascular system, including delayed intracardiac conduction and increased heart rate. Trazodone might have minor effects on heart rate and T wave changes. These drugs can interact with alcohol, potentially worsening adverse effects. These medications could be risky for individuals with heart conditions or other health problems, emphasizing the importance of use under medical supervision.

Comparison Between Studies

Commonalities

All these studies investigated the cardiovascular effects of various antidepressants. Each study employed double-blind, crossover or group comparison trials. All studies utilized therapeutic dosages of the medications.

Differences

The specific antidepressants used, the number of participants, and the duration of the trials varied across the studies. The research methodologies, including crossover trials, group comparison trials, and others, also differed between the studies.

Consistency and Contradictions of Results

These studies consistently suggest that femoxetine and mianserin have fewer significant adverse cardiovascular effects compared to amitriptyline. Trazodone also showed significantly fewer cardiovascular effects than amitriptyline. However, trazodone demonstrated minor effects on heart rate and T wave changes. Amitriptyline can affect the cardiovascular system, including delayed intracardiac conduction and increased heart rate. These research findings highlight the potential for different antidepressants to exert varying influences on the cardiovascular system.

Practical Implications and Precautions

These research findings suggest that antidepressants can have varying effects on the cardiovascular system. Individuals with heart conditions or other health problems should consult their physician before taking antidepressants. Those taking antidepressants should be mindful of potential cardiovascular side effects.

Limitations of Current Research

These studies involved a relatively small number of participants. Additionally, all studies were short-term trials. Long-term effects require further investigation.

Future Directions for Research

Research is necessary to investigate the long-term cardiovascular effects of these medications. Further investigation is needed to explore the varying influences of different antidepressants on the cardiovascular system. Studies are required to evaluate the effects of these medications on individuals with heart conditions or other health problems.

Conclusion

These studies suggest that various antidepressants can have different effects on the cardiovascular system. Individuals with heart conditions or other health problems should consult their doctor before taking antidepressants. Those taking antidepressants should be vigilant for potential cardiovascular side effects. Further research is needed to investigate the long-term cardiovascular effects of these medications.

Cardiovascular (ECG and systolic time intervals) and anticholinergic effects of repeated doses of femoxetine--a comparison with amitriptyline and placebo in healthy men.

Author: WarringtonS J, TurnerP, SkrumsagerB K

Fewer side effects
Increased heart rate

Femoxetine, a type of antidepressant, increased heart contractility and did not cause significant anticholinergic effects compared to amitriptyline, another antidepressant. Amitriptyline, on the other hand, caused a delay in intracardiac conduction and increased heart rate.

Interactions of alcohol with amitriptyline, fluoxetine and placebo in normal subjects.

Author: AllenD, LaderM

alcohol interaction

Amitriptyline, fluoxetine, and placebo were administered to healthy volunteers. Amitriptyline was poorly tolerated compared to fluoxetine. While both drugs showed limited effects on physiological and psychomotor function before alcohol, amitriptyline alone had a substantial effect on subjective measures, potentially masking additive or potentiating effects after alcohol.

A double-blind non-crossover placebo-controlled study between group comparison of trazodone and amitriptyline on cardiovascular function in major depressive disorder.

Author: van de MerweT J, SilverstoneT, AnkierS I, WarringtonS J, TurnerP

Safer than amitriptyline
Minor heart rate effect
T wave changes

Trazodone had fewer cardiovascular effects compared to amitriptyline, but long-term monitoring is needed to explain minor effects on heart rate and T wave changes.
