RESUMEN

The incidence of parathyroid hyperfunction is high and its clinical manifestations are diverse. Some patients develop chest tightness and palpitations as the main discomfort, which may be caused by the hypocalcemia and hypercalcemia related to negative calcium balance and parathyroid hyperfunction. We report a case of 53 years old male with parathyroid hyperfunction who was diagnosed with osteoporosis before and received conventional regular supplementation of vitamin D and calcium supplements. However, his condition worsened and he developed chest tightness and palpitation. After 1 month of sufficient supplementation of calcium, the symptoms of chest tightness and palpitation disappeared completely. Then we continued to provide the patients enough vitamin D and calcium supplementation actively. After 1 year of follow-up, the patient's condition was stable. His discomfort of chest tightness and palpitation never recurred, and all the bone metabolism indicators returned to normal.

RESUMEN

Phaeochromocytoma is indeed a rare and frequently misunderstood neuroendocrine tumor originating from chromaffin cells in the adrenal medulla. Its clinical presentation often includes paroxysmal hypertension, palpitations, headache, and diaphoresis, which can easily be mistaken for common medical conditions. Timely diagnosis and precise localization are paramount for ensuring the best possible outcomes for patients. In this case report, we describe an unusual presentation of phaeochromocytoma in a 36-year-old man who presented with acute myocarditis. This atypical manifestation underscores the diagnostic challenges associated with phaeochromocytoma, as its symptoms can mimic various other cardiac and non-cardiac conditions. Vigilant clinical evaluation and a multidisciplinary approach are essential for promptly recognizing and managing such cases, thus optimizing patient care and prognosis.

RESUMEN

Key Clinical Message: Middle-aged male athletes, with or without underlying coronary artery disease, exhibiting exercise induced blood pressure (BP) variability and diabetes can have an increased risk of developing atrial fibrillation (AF). Assessment in athletes should include long-term arrhythmia monitoring. In addition, it is important to exert patients beyond their calculated target heart rate (HR) during an exercise stress test to detect exercise-induced AF. We suggest this strategy be specifically used for athletes with complaints of intermittent palpitation and chest pain. Referral to an electrophysiologist for a possible ablation procedure should be considered for the management of AF in athletes in whom the use of beta-blockers may limit exercise tolerance. Bleeding risk with the use of oral anticoagulation needs to be adequately evaluated in athletes with AF who engage in high-intensity exercise or activities. Abstract: The report highlights the case of a 54-year-old Caucasian male (height 5.11', BMI 29.8) who presented with complaints of chest pain, mild coronary artery disease, palpitation, dizziness, and labile BP with high-intensity biking exercise. Diagnostic tests (exercise stress test, cardiac catheterization, Holter monitor, and Bardy patch) using standard procedure were unsuccessful at detecting the problem. In a repeat exercise stress test, the patient was exerted beyond the calculated HRmax (up to 117%) when the patient's heart rhythm flipped from sinus rhythm to AF. The patient was referred to a cardiac electrophysiologist and an ablation procedure was performed to prevent exercise-induced AF with high-intensity exercise. Young adults, with or without early coronary artery disease, performing high-intensity endurance exercises may be at risk of developing exercise-induced AF. This phenomenon is prevalent and well documented in the skiing population and patients with variance in BP during exercise. Endurance athletes tend to have a lower resting HR. As such, the use of standard rate-control medications in patients with exercise-induced AF may not be appropriate. Referral to a cardiac electrophysiologist and ablation procedures should be considered in this population for management and symptom control. If tolerated, especially in young adults with complaints of palpitation and chest pain, patients should be exerted beyond their calculated HRmax during an exercise stress test to diagnose an underlying condition of exercise-induced AF.

RESUMEN

Hypertensive heart disease presents increasing morbidity and mortality worldwide, however, the data about its epidemics and its specific symptoms in hypertension patients is scarce. To assess the frequency and correlated symptoms of hypertensive heart disease, 800 hypertension patients were randomly recruited for this study per the guidelines of the American College of Cardiology. The diagnosis of heart disease and its typical symptoms (palpitation and angina) were analyzed for the frequency of hypertensive heart disease in hypertension cohort. Cross-tabulation analysis was used to study the correlation between psychiatric indexes (annoy, amnesia, irritableness, depression, anxiety, and fear) and palpitation, the correlation between physical disorders (backache, lumbar debility, and numbness of limbs) and palpitation, and the correlation between symptoms (dizziness, daze, headache, and tinnitus) and palpitation presented in hypertensive patients. It was found that around half of patients suffered hypertensive heart disease, which correlated to certain physical and mental symptoms. Significant correlation exists between palpitation and annoy / amnesia. Significant correlation exists between palpitation and backache / lumbar debility / numbness of limbs; and significant correlation exists between palpitation and dizziness / daze / headache / tinnitus. These results provide clinical insights into the modifiable antecedent clinical conditions which are risk factors for hypertensive heart disease in elderly and will help improve early management of this disease.

RESUMEN

Many patients with palpitation consult outpatient cardiology departments. They may present with cardiac tuning abnormality (arrhythmia), which manifests as morbid palpitations. Appropriate diagnosis and treatment of palpitation are crucial to prevent adverse cardiac events. However, palpitations, in addition to anxiety and dyspnea, are often not considered as significant factor for morbidity in Western medicine. Conversely, Kampo (traditional Japanese medicine) can be used to treat the constitution of the patients, including those with or without disease diagnosed by Western medicine. However, there are no reports on the efficacy of Kampo in many examples. In this study, we diagnosed and provided appropriate Western medicine treatment for 101 outpatients with palpitation who consulted our department. We give priority to it if we evaluate the treatment of the disease of Western medicine was required (group W : n = 19). When an appropriate diagnosis could not be made by Western medicine, or when no therapeutic effect was noted with Western medicine, we administered Kampo medicine alone (group K : n = 62) or combination therapy (Kampo and Western medicine ; group KW : n = 20). The treatment efficacy was evaluated in each of the three groups. We observed high efficacy in all 3 groups (group W = 100%, group K = 96%, and group KW = 100%). Therefore, for patient with palpitation, combined treatment with both Kampo and Western medicine could improve their symptoms.

RESUMEN

BACKGROUND: It is reported that the adverse impact of nonpharmaceutical interventions (NPIs) on the mental health of children and adolescents may lead to psychologically related disorders during the coronavirus disease 2019 (COVID-19) period. Subject symptoms such as chest pain, chest tightness, and palpitation may be related to increased stress and anxiety in children and adolescents. The present research aimed to determine the number of pediatric consults and etiology of subject symptoms during the COVID-19 pandemic period and compared it with the same timelines in 2019 and 2021 to discuss the impact of different periods on the organic disease onset of children with subject symptoms, especially in cardiac involvement. METHODS: Children who visited Qingdao Women and Children's Hospital, Qingdao University between January 23 to April 30, 2019 (pre-COVID-19 period), January 23 to April 30, 2020 (COVID-19 period), and January 23 to April 30, 2021 (post-COVID-19 period) presenting chest pain, chest tightness, and palpitation were recruited. Information to determine gender, age, medical history, department for the initial visit, clinical manifestations, time from the latest onset to the visit, and diagnosis were recorded. RESULT: A total of 891 patients were enrolled in the present study (514 males; median age: 7.72). One hundred twenty-three patients presented during the pre-COVID-19 period while 130 during the COVID-19 period, nevertheless, the number substantially increased during the post-COVID-19 period (n = 638). Cardiac etiology accounted for 1.68% (n = 15) of the patient population, including arrhythmias (n = 10, 1.12%), myocarditis (n = 4, 0.44%), and atrial septal defect (n = 1, 0.11%). There was no significant difference among groups in the distribution of organic etiology. The median time from the latest onset to the visit during the pre-COVID-19 period was 7 days compared to 10 days during the COVID-19 period and 3 days during the post-COVID period. CONCLUSION: During the post-COVID-19 period, the median time from the latest onset to the visit was significantly shorter than that in the pre-COVID-19 period or COVID-19 period. The pediatric consult of children with subject symptoms presented increased substantially during the post-COVID-19 period, while there was no significant difference in the number of patients involving the cardiac disease. Clinicians ought to be more careful to screen heart diseases to prevent missed diagnosis and misdiagnosis during special periods.

RESUMEN

Postural orthostatic tachycardia syndrome (POTS) is a form of dysautonomia that's characterised by an abnormal heart rate response to a positional change. A 50-year-old female presented with lightheadedness, palpitation, and neck pain for 3 years. Lightheadedness and palpitation occurred when shifting from a prolonged seated or lying position. Standing radiographs showed spinal misalignment with cervical kyphosis and thoracic scoliosis. Continuous static stress on these minor variants could aggravate biomechanical and autonomic disorder like POTS. After ruling out cardiovascular, neurological, or vestibular pathophysiology, a multicomponent treatment approach was adopted including the use of thermal ultrasound therapy, cervical and thoracic spinal manipulation, and intermittent motorized cervicothoracic traction to manage her neck pain complaints. Following 3 months of regular treatment, the patient reported a full resolution of neck pain, dizziness, and POTS. At 12-month follow-up, all radiographic metrics showed improvement, including improvement of cervical alignment and thoracic curvature. POTS is a prevalent, under-diagnosed dysautonomia. This study might arouse the alertness of clinicians that symptoms related to POTS may be erroneously attributed to other neuro-cardiovascular disorders.

RESUMEN

Narcolepsy is a clinical syndrome of hypothalamic disorder characterized by several sleep-wake disorders. The most common features include daytime sleepiness associated with hallucinations (hypnagogic and hypnopompic hallucinations) at the transition time of sleep-wake time, cataplexy or sudden loss of muscle tone, and sleep paralysis. We present a case of a patient affected with both narcolepsy and postural orthostatic tachycardia syndrome (POTS). POTS is a rare disorder characterized by orthostatic intolerance and abnormal autonomic response while sustaining an upright posture. In this case report, we highlight the impact of POTS on the choice of pharmacotherapy for narcolepsy.

RESUMEN

Complicated vomiting and hypercalcemia are clinically rare in patients with hyperthyroidism. We describe a case of a woman whose main symptoms were palpitations, sweating, and vomiting. She was diagnosed with Graves' disease by an analysis of thyroid function, thyroid-related antibodies, and color Doppler ultrasound. Biochemical tests showed that her serum calcium levels were greatly elevated. Her symptoms were relieved following the administration of antithyroid drugs, propranolol for heart rate control, fluid replacement, diuresis and calcium reduction, antiemesis, and liver protection. This case suggests that the thyroid function should be screened when hypercalcemia is seen in the clinic.

RESUMEN

Coronary artery dilatation has been observed with coronavirus disease 2019 (COVID-19)-associated multisystem inflammatory syndrome in children (MIS-C), which is more common in those with Kawasaki-like disease. MIS-C is a clinical syndrome in children and adolescents; its signs and symptoms, as well as cardiac manifestations, are similar to Kawasaki diseases, such as coronary artery dilation, coronary aneurysms, and ventricular dysfunction. The occurrence of coronary artery dilatation in asymptomatic pediatric patients following COVID-19 infection has not been well documented in the literature. Thus, in this article, we present four cases of coronary artery dilation in children with a past history of COVID-19 infection who had very few or no symptoms and were referred to us for vague chest pain and palpitation. As a result, a high index of suspicion is required, and any patient complaining of chest pain and palpitation with a history of COVID-19 exposure should not be ignored and be given proper coronary artery evaluation. This article also raises the question of whether every child infected with COVID-19 should have an echocardiogram.

RESUMEN

BACKGROUND AND AIM: Mitral valve prolapse (MVP) is a common disease in women, causing chest pain and palpitation due to structural and functional valve abnormality, and is sometimes associated with gastro-oesophageal reflux disease (GERD). This is a challenging clinical problem in clinical practice and requires targeted diagnostic assessment to identify the underlying causes of the symptoms, because treatment needs to be tailored, according to the causes themselves, to resolve the symptoms. AIM: To assess the prevalence of GERD in a population of postmenopausal women affected by MVP and determine if there is any correlation between the two conditions. METHODS: The MVP diagnosis was performed using echocardiograpy examination, according to American Society Echocardiography criteria. Two hundred and eighty-nine consecutive MVP women, symptomatic for chest pain and palpitation, were included; 250 consecutive women without MVP, symptomatic for chest pain and palpitation, were the control group (CG). The GERD diagnosis was made according to 2013 American College Gastroenterology criteria; women affected by thyroid disorders, all heart disease, including mitral disease with moderate or severe mitral regurgitation, and gastrointestinal diseases assessed using gastroscopy were excluded. RESULTS: Among 289 women with MVP, 31 (11%) women were affected by GERD, and among 250 in the CG, 11 (4.4%) women were affected by GERD: Chi-squared 8.1; odds ratio 2.7; P < 0.0044. Twenty-six (9%) women affected by GERD, with MVP, presented with mild mitral regurgitation, and 7 (2.8%) women in the CG presented with mild mitral regurgitation as well: Chi-squared 8.95; odds ratio 3.4; 95% CI, P < 0.0028. DISCUSSION AND CONCLUSIONS: GERD is relatively common in women with MVP. Moreover, women with MVP are approximately three times more likely to be affected by GERD; the two conditions are correlated in a statistically high significant way. GERD assessment needs to be included into routine follow-up strategies in women with MVP to optimise medical therapy, improvinge symptom relief for better quality of life.

RESUMEN

BACKGROUND: The goal of this study was to evaluate any association between physical symptoms and abnormal clinical history in adolescence undergoing screening echocardiography performed by Anthony Bates Foundation. METHOD: The Anthony Bates Foundation has been performing screening echocardiography across the United States for the prevention of sudden death since 2001. We performed uni- and multivariate analysis to evaluate any association between physical symptoms with gender, smoking, obesity, heart rate, and hypertension. RESULTS: We found a strong association between symptoms and the female gender (33% vs. 17.5% of males, P < 0.001). Furthermore, obesity (46.5% vs. 22.5%, P < 0.001), smoking (46.2% vs. 22.5%, P = 0.04), heart rate > 90 (34.8 vs. 22.8%, P = 0.001), and diastolic blood pressure > 90 (34.9% vs. 23.4%, P = 0.03) were all associated with symptoms. Increased systolic pressure was not associated with physical symptoms (24.3% vs. 21.9%, P = 0.4). Using multivariate analysis, female gender, diastolic blood pressure and obesity remained independently associated with physical symptoms. (Female gender: OR: 2.2, CI: 1.7-2.9, P < 0.001, obesity: OR: 2.5, CI 1.2-5.05, P = 0.009, and high diastolic blood pressure: OR: 2.08, CI 1.1-3.7, P = 0.01). CONCLUSION: Physical symptoms are associated with smoking, female gender, obesity, tachycardia, and high diastolic blood pressure but not systolic pressure in adolescence undergoing routine screening echocardiography.

RESUMEN

In this study, we report our experience with the use of external loop recorders (ELRs), in terms of diagnostic efficiency according to symptoms and symptom-rhythm correlation in pediatric patients. We evaluated ELRs applied to 178 patients between April 2017 and November 2020 at our center. The mean age of 172 patients included in the study was 13.6 ± 3.8 years, and 69.8% were female. ELR indications were palpitations in 98 (56.9%) cases, chest pain and palpitations in 43 (25%) cases, presyncope/syncope in 28 (16.2%) cases, and pacemaker/ implantable cardioverter-defibrillator (ICD) problems in 3 (0.2%) cases. ELR recording times were 14.2 ± 9.7 days on average, ranging from 2 to 67 days. While the symptom-rhythm correlation was 29.1% in total, when the indications were evaluated one by one, this correlation was found to be 30.2% in palpitations, 34.7% in chest pain and palpitations, and 10.7% in presyncope/syncope. The total diagnostic efficiency was 68.1%. In the follow-up of ELR cases, a total of 139 (80.8%) patients received clinical follow-up without medication, 15 (8.8%) patients received medical treatment, and 18 (10.4%) patients underwent EPS. The cardiac ELR system is useful in detecting underlying arrhythmias. Demonstrating sinus tachycardia at the time of the symptom may be seen as negative finding, but while experiencing symptoms, it is diagnostically valuable and may help avoid further investigation with costly and invasive diagnostic procedures. For diagnostic efficiency and cost effectiveness, the optimal recording time is 2 weeks, but it should be extended to 4 weeks in cases such as of presyncope/syncope that cannot be explained with a 2-week ELR use.

RESUMEN

Palpitations are one of the most common reasons for medical consultation. They tend to worry patients and can affect their quality of life. They are often a symptom associated with cardiac rhythm disorders, although there are other etiologies. For diagnosis, it is essential to be able to reliably correlate the symptoms with an electrocardiographic record allowing the identification or ruling out of a possible rhythm disorder. However, reaching a diagnosis is not always simple, given that they tend to be transitory symptoms and the patient is frequently asymptomatic at the time of assessment. In recent years, electrocardiographic monitoring systems have incorporated many technical improvements that solve several of the 24-h Holter monitor limitations. The objective of this review is to provide an update on the different monitoring methods currently available, remarking their indications and limitations, to help healthcare professionals to appropriately select and use them in the work-up of patients with palpitations.

RESUMEN

Background: Vaccination against SARS-CoV-2 is important for reducing hospitalization and mortalities. Both Pfizer-BioNTech (BNT162b2) and the Oxford-AstraZeneca (ChAdOx1 nCoV-19) vaccines are used in Saudi Arabia and in many parts of the world. Post-vaccinal side effects were recorded, so we aimed to screen different complaints after vaccination among vaccinees in Saudi Arabia. Methods: An online questionnaire was designed to screen the local, systemic, and allergic post vaccination reactions for vaccinees who received either one or two doses of the BNT162b2 vaccine or one dose of the ChAdOx1 vaccine. The number and percentage were recorded for each response and analyzed using cross-tab and Chi square tests. The degree of the severity of post vaccination reactions were analyzed using Roc curve. The cofactors that may affect the severity of post-vaccinal reactions including previous COVID-19 infection, age, sex, body mass index, and comorbidities were investigated. Results: During our study, 4,170 individuals reported their responses: 2,601 received one dose of BNT162b2, of whom 456 completed the second dose, and 1,569 received a single dose of ChAdOx1. The side effects were reported in 85.6% of BNT162b2 vaccinees and 96.05% of ChAdOx1 vaccinees who voluntarily responded to a survey about post-vaccination side effects. The side effects were more severe in BNT162b2 than ChAdOx1. ChAdOx1 vaccinees reported mild, moderate, severe and critical side effects in 30.13, 28.62, 29.73, and 1.53%, respectively. In contrast, mild side effects were recorded among the majority of BNT162b2 vaccinees (63.92%) while moderate, severe, and critical side effects were 27.67, 7.68, and 0.72%, respectively. Both local and systemic side effects were recorded more frequently in ChAdOx1 in comparison to BNT162b2 vaccinees. Palpitation was among the new systemic side effects reported in the current study in high frequency. Abnormal menstrual cycle (delaying/increase hemorrhages or pain) was also reported in 0.98% (18/1846) of Pfizer-BioNTech and 0.68% (7/1028) of ChAdOx1 vaccinees, while deep vein thrombosis was only reported in a single case vaccinated with BNT162b2 vaccine. Conclusion: Both vaccines induced post-vaccinal side effects; however, ChAdOx1 induces a higher frequency of post-vaccinal systemic side effects than BNT162b2.

RESUMEN

Hereditary paraganglioma-pheochromocytoma (PGL/PCC) syndrome is an uncommon genetic condition featured by an inherited predisposition to generate PGLs. Surgical resection of all tumors is the standard treatment for excess adrenaline production and tendency for metastasis. Nowadays, there are few case reports that have mentioned the surgical technique for hereditary PGL/PCC syndromes, especially robot-assisted surgery. Herein we present a rare case of hereditary PGL/PCC syndromes treated by partial cystectomy and right adrenalectomy at the same time with modified dual docking robotic surgical technique. Our dual docking robotic technique is a feasible option for patients with hereditary PGL/PCC syndromes of synchronous tumors in bladder and adrenal gland. It could not only prevent from second surgery but be safely performed without compromising disease control.

RESUMEN

Short RP interval atrioventricular re-entrant tachycardias do not typically present as an incessant form. We present 2 cases of incessant atrioventricular re-entrant tachycardias leading to tachycardia-induced cardiomyopathy with severe heart failure presentation in middle-aged adults. Both underwent accessory pathway ablation and recovered normal left ventricle function before hospital discharge. (Level of Difficulty: Intermediate.).

RESUMEN

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was declared a pandemic by the World Health Organization in March 2020. Initially, infected patients presented with fever, nonproductive cough, dyspnea, myalgia, shortness of breath, and radiographic evidence of pneumonia. However, others presented with atypical cardiac manifestation. As this disease is new, the full picture of the disease presentation is not fully understood. Since December 2019, many morbidities related to coronavirus disease-2019 (COVID-19) were documented, including vascular complications like venous thromboembolism (VTE), pulmonary embolism (PE), and deep vein thrombosis (DVT) in acutely ill COVID-19 patients. Hereby, we are writing a case of a patient with COVID-19 infection suffering from new-onset atrial fibrillation (AF). It was complicated by multiple arterial embolisms involving different organs despite the use of an intermediate dose of low-molecular-weight heparin (LMWH), and the patient was eventually discharged home on a direct-acting oral anticoagulant (DOAC).
