The cardiovascular response to sexual activity: do we know enough?

Physiological Synchrony During Partnered Sexual Activity

Physiological synchrony (PS) refers to the coordination of bodily responses in close relationships. It seems to be linked to relational well-being, satisfaction, closeness, and empathy. Recent research extends these findings to sexual relationships as well, with evidence suggesting that PS may predict attraction and sexual satisfaction. The current study focuses on PS during sexual activity within established couples. Results suggest that PS develops during sexual activity, in certain contexts, and tends to be greater in magnitude during sexual encounters than during non-sexual interactions. Results may shed light on the dyadic psychophysiological factors relevant to sexual experiences.

Improvement in Sexual Dysfunction in Patients With Hypertrophic Cardiomyopathy Undergoing Septal Myectomy: A Prospective Study

Background

Septal myectomy improves symptoms in the majority of patients with obstructive hypertrophic cardiomyopathy (HCM), but there are limited prospective data on functional outcomes after operation.

Objectives

The authors investigated quality of life measures and prevalence of sexual dysfunction before and after septal myectomy for obstructive HCM.

Methods

Between January 2018 and October 2019, 436 patients underwent transaortic septal myectomy at our clinic. All patients were screened for eligibility, and 197 (45.2%) were enrolled in this prospective survey study. Patients received a questionnaire pertaining to quality of life and sexual health before and within 4 to 6 months postoperatively, and 113 (57.4%) completed the follow-up survey.

Results

The mean age of the 54 (47.8%) women and 59 (52.2%) men was 54.7 ± 14.1 years. Quality of life, including both mental and physical components, improved significantly in both men (P < 0.001) and women (P < 0.001). Women reported mild sexual dysfunction at baseline, and following septal myectomy, they experienced significant (P < 0.05) improvement in most domains pertaining to sexual health. In men, the International Index of Erectile Function median score was 23 (IQR: 7.0-29.5), which is consistent with mild dysfunction at baseline, and there was significant improvement following surgery in young (age ≤55 years) men (P < 0.001).

Conclusions

Quality of life is significantly improved following septal myectomy in patients with obstructive HCM. Both women and men reported mild sexual dysfunction at baseline, and women and younger men (age ≤55 years) experienced significant improvements in sexual health.

What Are the Physical Demands of Sexual Intercourse? A Systematic Review of the Literature

The aim of this study was to systematically review the literature investigating the physical demands of sexual intercourse and to synthesize the evidence related to this research topic. Original studies published on PubMed, Scopus, and Web of Science up until April 2020 were examined. The Effective Public Health Practice Project scale was used to assess the methodological quality of each study. Eighteen studies analyzed physical demands during sexual intercourse through the physiological demands (n = 14) and kinematics (n = 4) of sexual intercourse. Sexual intercourse can elicit an energy expenditure of ~ 100 kcal (or ~ 6 metabolic equivalent units, METs) during the activity, mean heart rates between ~ 90 and ~ 130 beats per minute (bpm), and peak heart rates up to ~ 170 bpm. However, these physical demands may vary depending on health status, intercourse position, activity duration, intercourse phase, and sex differences. The movement pattern was cyclic in all positions and the greatest demands in lumbar spine flexion were found in the missionary positions for women. Missionary and side-lying positions elicited the greatest lumbar flexion movement in men. Regarding the movement of the hip joint during sexual intercourse, flexion, abduction, and external rotation mainly characterized the woman's movement while external rotation did so in the man. In conclusion, sexual intercourse may elicit moderate intensity physical demands, but these demands vary depending on contextual variables. In addition, not only studies combining physiological and kinematic analyses are necessary but also more high-quality studies need to be published in order to have a better understanding of the physical demands of sexual intercourse.

Sexual incentive motivation, sexual behavior, and general arousal: Do rats and humans tell the same story?

Sexual incentive stimuli activate sexual motivation and heighten the level of general arousal. The sexual motive may induce the individual to approach the incentive, and eventually to initiate sexual acts. Both approach and the ensuing copulatory interaction further enhance general arousal. We present data from rodents and humans in support of these assertions. We then suggest that orgasm is experienced when the combined level of excitation surpasses a threshold. In order to analyze the neurobiological bases of sexual motivation, we employ the concept of a central motive state. We then discuss the mechanisms involved in the long- and short-term control of that state as well as those mediating the momentaneous actions of sexual incentive stimuli. This leads to an analysis of the neurobiology behind the interindividual differences in responsivity of the sexual central motive state. Knowledge is still fragmentary, and many contradictory observations have been made. Nevertheless, we conclude that the basic mechanisms of sexual motivation and the role of general arousal are similar in rodents and humans.

Sexual Knowledge in Post-Myocardial Infarction Patients: A Cross-Sectional Study

Background

Adequate sexual knowledge is a key component of cardiac rehabilitation. Sexual knowledge in post-myocardial infarction (MI) patients is unknown. Thus, we conducted this study to investigate the sexual knowledge of post-myocardial infarction patients and their accessibility to sexual counseling.

Methodology

Between July and September 2018, a cross-sectional survey was carried out in 6six major hospitals in Karachi. The non-probability convenient sampling technique was used to include all patients meeting the inclusion criteria. To reduce biases, face-to-face interviews were conducted by investigators who were trained prior to the start of data collection. Knowledge was assessed using the Swedish version of the "Sex after MI Knowledge Test" questionnaire, where a higher score meant higher knowledge. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0 (IBM Corp., Armonk, NY) The t-test was applied to compare the knowledge score between males and females.

Results

There was a total of 278 MI patients with a mean age of 54 years, of which 60% were men. The "Sex After MI Knowledge Test" scores varied between 37 and 67 (mean score 51 ± 5). None of the participants obtained the maximum possible test score of 75. The most frequently occurring score was 49 (16%). Around half of the participants (48%) incorrectly believed that sex cannot be safely resumed within a few weeks after the heart attack. Limited knowledge was found in questions pertaining to alcohol, viagra, and late evening being the best time to have sex. Medical knowledge was provided to only 27% (n=76) of the participants, of whom 77% (n=58) received it from the hospital staff itself. A significant difference existed in scores obtained by males and females, with males having a higher score and the mean difference in scores being 1.7 (p=0.015).

Conclusion

Lack of sexual knowledge in MI patients due to the inadequacy of healthcare providers and the social stigma surrounding the topic causes marital strain leading to low quality of life.

Sexual activity-related emergency department admissions: eleven years of experience at a Swiss university hospital

PRINCIPALS

Most people enjoy sexual intercourse without complications, but a significant, if small, number need to seek emergency medical help for related health problems. The true incidence of these problems is not known. We therefore assessed all admissions to our emergency department (ED) in direct relation to sexual intercourse.

METHODS

All data were collected prospectively and entered into the ED's centralised electronic patient record database (Qualicare, Switzerland) and retrospectively analysed. The database was scanned for the standardised key words: 'sexual intercourse' (German 'Geschlechtsverkehr') or 'coitus' (German 'Koitus').

RESULTS

A total of 445 patients were available for further evaluation; 308 (69.0%) were male, 137 (31.0%) were female. The median age was 32 years (range 16-71) for male subjects and 30 years (range 16-70) for female subjects. Two men had cardiovascular emergencies. 46 (10.3%) of our patients suffered from trauma. Neurological emergencies occurred in 55 (12.4%) patients: the most frequent were headaches in 27 (49.0%), followed by subarachnoid haemorrhage (12, 22.0%) and transient global amnesia (11, 20.0%). 154 (97.0%) of the patients presenting with presumed infection actually had infections of the urogenital tract. The most common infection was urethritis (64, 41.0%), followed by cystitis (21, 13.0%) and epididymitis (19, 12.0%). A sexually transmitted disease (STD) was diagnosed in 43 (16.0%) of all patients presenting with a presumed infection. 118 (43.0%) of the patients with a possible infection requested testing for an STD because of unsafe sexual activity without underlying symptoms.

CONCLUSIONS

Sexual activity is mechanically dangerous, potentially infectious and stressful for the cardiovascular system. Because information on ED presentation related to sexual intercourse is scarce, more efforts should be undertaken to document all such complications to improve treatment and preventative strategies.

Incidence of sexual dysfunction in men after cardiac surgery in Afshar hospital, Yazd

BACKGROUND

Successful rehabilitation of cardiac surgery patients should include consideration of their sexual activity, but there is paucity of data regarding this matter.

OBJECTIVE

This study determined the incidence and type of sexual dysfunction in our patients.

MATERIALS AND METHODS

Two hundred-seventy nine men with age under 70 years old who had coronary artery bypass graft (CABG), valvular, or other types of cardiac surgery from Dec. 2006 until Dec. 2007 were enrolled in this descriptive-analytical study. They were interviewed before and 12 weeks after the operation in regard to the impact of surgery on their sexuality. The statistical methods used included analysis of variance, Kappa test, and chi-square analysis.

RESULTS

The mean age of the patients was 55.7 ± 10.66 (25-69) years. The incidence of sexual dysfunction was 20.1% before, and76.4%, 12 weeks after the operation. P-valueas tested by Kappa test was 0.0001, which means that cardiac surgery had adverse effect on sexual activity of the patients. Types of sexual dysfunction were impotence, premature ejaculation, and decreased or loss of libido in 6.5%, 4.3% and 9.3%, respectively before operation, and 34.8%, 21.5% and 20.1%, respectively 12 weeks after the operation. Concurrence of more than one dysfunction was not reported.

CONCLUSION

Sexual dysfunction is common after cardiac surgery, and sexual counseling is still not being addressed adequately. The role and responsibility of the physician and the rehabilitation nurse becomes evident, together with the need for the patient's partner to participate in counseling.

Doppler evaluation of erectile dysfunction – Part 1

Erectile dysfunction (ED) is the consistent inability to achieve and maintain an erection sufficient for satisfactory sexual activity. Erectile dysfunction affects as many as 30 million men in America, with an increasing prevalence with age. Erectile dysfunction is secondary to organic, psychogenic and combined causes. The first part of this review article describes the guidelines for evaluation and treatment plans for men with ED. It also describes the normal sonographic anatomy of the penis, sonographic technique for evaluation of ED and the normal phases of erection.

Sexual activity and function in postmenopausal women with heart disease

OBJECTIVE

To examine the prevalence and correlates of sexual activity and function in postmenopausal women with heart disease.

METHODS

We included baseline self-reported measures of sexual activity and the sexual problem scale from the Medical Outcomes Study in the Heart and Estrogen/Progestin Replacement Study (HERS), a study of 2,763 postmenopausal women, average age 67 years, with coronary disease and intact uteri. We used multivariable linear and logistic regression to identify independent correlates of sexual activity and dysfunction.

RESULTS

Approximately 39% of the women in HERS were sexually active, and 65% of these reported at least 1 of 5 sexual problems (lack of interest, inability to relax, difficulty in arousal or in orgasm, and discomfort with sex). In multivariable analysis, factors independently associated with being sexually active included younger age, fewer years since menopause, being married, better self-reported health, higher parity, moderate alcohol use, not smoking, lack of chest discomfort, and not being depressed. Among the 1,091 women who were sexually active, lower sexual problem scores were associated with being unmarried, being better educated, having better self-reported health, and having higher body mass index.

CONCLUSION

Many women with heart disease continue to engage in sexual activity into their 70s, and two thirds of these report discomfort and other sexual function problems. Physicians should be aware that postmenopausal patients are sexually active and address the problems these women experience.

Investigations in erectile dysfunction

PURPOSE OF REVIEW

This is an update of recent developments in the investigation of erectile dysfunction in the period since March 2002.

RECENT FINDINGS

Three developments in the field of medical sexology redirected the approach towards the investigation of erectile dysfunction. First, the emergence of oral pharmacological therapy; second, the notion that sexual relationship issues have an important impact on the successful outcome of pharmacological therapy; and finally, the concept that erectile dysfunction is often a sequel or even a sentinel of cardiovascular disease. Consequently, the current evaluation of men with erectile dysfunction may be divided into two steps: a basic diagnostic evaluation for the majority of men, and specific diagnostic procedures for a small minority. The basic evaluation is aimed at the identification of the underlying pathological condition and erectile dysfunction-associated risk factors. Such screening may diagnose reversible causes of erectile dysfunction and also unmask medical and psychological conditions that manifest with erectile dysfunction. The basic evaluation consists of a comprehensive medical, sexual and psychosocial history and a physical examination. Patients who have failed first-line treatment or complicated cases qualify for specific diagnostic procedures, traditionally performed by urologists.

SUMMARY

Current research into the investigation of erectile dysfunction emphasizes the notion that erectile dysfunction is often a result of an interplay between medical and psychosexual conditions. Recognition of the underlying conditions and an estimation of their relative contribution to the patient's and his partner's sexual problem are key issues in the current evaluation of the man with erectile dysfunction.
