There is a definite correlation between cardiovascular diseases and depressive disorders. Nevertheless, many aspects of this association have yet to be fully elucidated. Pharmacotherapy is a key factor in the management of major depression, not least in patients with chronic diseases who are likely to fail to show proper compliance and response to non-pharmacological interventions.
Antidepressants are not deemed completely safe, cardiovascular problems and depression. Indeed, numerous side effects have been reported with the administration of antidepressants, among which cardiovascular adverse events are of paramount importance owing to their disabling and life-threatening nature.
A definite correlation exists between cardiovascular diseases CVD and depressive disorders, yet many aspects of this relationship have remained cardiovascular problems and depression. The diagnosis may be further complicated in such patients by their responses to their disease, which may include denial, cardiovascular problems and depression, avoidance, withdrawal, and antibiotics and gastritis. According to the World Health Organization WHO reports, ischemic heart disease is now the leading cause of death worldwide and bydepression will have the greatest burden among diseases in terms of years lost due to disability.
Pharmacotherapy plays a key role in the management of cardiovascular problems and depression depression, especially in patients with chronic diseases who do not usually show proper compliance and response to non-pharmacological interventions.
Many of these unfavorable reactions with antidepressants can be prevented by increasing the knowledge of physicians exporant and clomid patients about basic processes and clinical cautions in this regard. Given these challenges, we aimed to review some of the most important issues in antidepressant therapy with regard to cardiovascular considerations that should be kept in mind when prescribing such medications.
Although antidepressants are commonly used in clinical setting, numerous negative effects of antidepressants on the cardiovascular system have been reported to date, including bradycardia, tachycardia, hypertension, hypotension, orthostatic hypotension, electrocardiogram ECG changes, electrolyte abnormalities, reduced cardiac conduction and output, arrhythmias, and sudden cardiac death.
Because of its prevalence and life-threatening consequences, arrhythmia is then further discussed in a separate section. Antidepressant factor v leiden and warfarin are classified as first or second generation: Even though MAOIs are effective in improving depressive symptoms, various unfavorable side effects and drug interactions significantly limit their clinical application.
Since a period of time is needed to establish such neurotransmitter disturbances, cardiovascular adverse events are usually seen hours after MAOIs have reached their toxic levels. A hypertensive crisis can occur when tyramine-containing foods such as aged cheese are ingested along with MAOIs, which is due to epinephrine, norepinephrine, and dopamine release. However, cardiovascular problems and depression, hypotension has been reported as well.
At therapeutic levels, TCAs are able to block alpha-adrenergic receptors and reduce systemic vascular resistance. Therefore, they may cause hypotension or orthostatic hypotension, especially in case of dehydration or concurrent use of antihypertensive medications. Because of the serious unfavorable effects and potential cardiotoxic nature of TCAs, these agents should be prescribed cautiously not only in patients with CVD but also in individuals without prominent cardiovascular complaints.
Accordingly, close monitoring of patients receiving TCAs with particular attention to cardiovascular markers seems to be mandatory. Cardiovascular adverse events are usually mild and are unlikely to occur with SSRIs at therapeutic doses. Interestingly, it has been suggested that SSRIs may even have some benefits for the cardiovascular system through complex mechanisms. SSRIs users have been shown to experience lower rates of myocardial infarction compared with the other types of antidepressant, particularly TCAs.
SSRIs should not be assumed to be completely safe from cardiovascular point of view. Although these are usually first-line antidepressant agents, a growing number of reports are emerging on cardiovascular complications cardiovascular problems and depression to SSRIs use, the most important of which are arrhythmias and syncope.
In addition to serotonin, SNRIs also inhibit the reuptake of norepinephrine from the synaptic cleft, resulting in increased neurotransmission. Increased levels norepinephrine and serotonin can accelerate cardiac sympathetic activity, leading to a mild increase in heart rate and systemic blood pressure.
In general, these agents show minimal cardiovascular side effects. Arrhythmias are one of the most critical and important side effects of antidepressant agents. Different categories of antidepressants, particularly TCAs, provoke various types of arrhythmias through complex processes involving voltage-gated sodium, potassium, cardiovascular problems and depression, and calcium ion channels in cardiac myocytes and conduction system. The QT interval of the ECG is generally accepted as the predictive parameter for predisposition to arrhythmia.
In healthy individuals, the mean QTc length is approximately milliseconds ms. Some antidepressants can bind to cardiac inward-rectifier potassium ion channels and block the efflux of potassium from cardiac myocytes, leading to the prolongation of repolarization phase and QT interval. In addition to the ECG markers, HRV is known as a relatively more reliable predictor of arrhythmia occurrence, particularly in some specific patients erectile dysfunction and extreme tiredness as those with CAD, chronic heart failure, and diabetes mellitus 7879 Cardiac arrhythmias may develop in a person with a normal ECG, but HRV almost always shows some degrees of abnormality before arrhythmia occurrence.
Variability in the heart rate is regulated by autonomic innervations and a high degree of beat-to-beat variability is seen in a normal functioning heart. This HRV provides a protective mechanism against many assaults such as myocardial infarction and heart failure. Cardiovascular problems and depression antidepressant agents, TCAs markedly reduce HRV through their profound impact on adrenergic and cholinergic systems, cardiovascular problems and depression.
It has been proven that amelioration of depressive symptoms has beneficial advantages on the survival of patients who suffer from both HF and depression. Patients who respond to antidepressant therapy within the first year of treatment have shown to experience significantly diabetes and anal itcing rates of morbidity and mortality.
However, the results of a large-scale randomized placebo-controlled clinical trial showed that Sertraline administration was cardiovascular problems and depression but not efficient for improving depression in these patients. Evidence shows that the occurrence of acute coronary syndromes ACS doubles the risk of developing MDD in affected individuals. On the one hand, deficits cardiovascular problems and depression such neurotransmitters are attributed to the pathophysiology of depression.
On the other hand, several lines of evidence shows that these abnormalities are involved in the stiffening and narrowing of arteries as well as increased endothelial reactivity seen in the different types of CAD. These changes predisposes vessel plaques to be unstable and along with hemodynamic factors may eventually result is plaque rupture, thrombosis, and subsequent ACS. Choosing the best strategy to treat depression in patients with ACS is still a big challenge and we face a relative inconsistency in the literature in this regard.
Due to serious cardiovascular events reported with TCAs use, this class of antidepressants is totally contraindicated in patients with ACS. Several lines of evidence indicate that different cardiovascular considerations should be inspected in patients who need to take antidepressant medications. Since there is no robust clinical guideline yet, patients should be individually evaluated with respect to their potential risks and benefits from antidepressant therapy.
Periodical monitoring with the ECG is also required to detect probable QT prolongation or other substantial ECG cardiovascular problems and depression indicative of increased risk of serious arrhythmias.
Further basic and clinical studies are warranted to reach a relative consensus in selecting appropriate antidepressant regimen for each patient and subsequently avoid life-threatening cardiovascular adverse events due to depression treatment.
