Hiatal hernia (HH) is a common disease in the general population. It is often asymptomatic, but if it does present clinical manifestations, these are usually gastrointestinal. Gastroesophageal reflux is the main symptom that accompanies it. Depending on the severity of the hernia, it is classified into several subtypes from I–IV. Especially, IV type (giant HH) can lead to various cardiopulmonary symptoms with several degrees of severity. It is necessary to keep this possibility in mind among the various differential diagnoses that may occur in this clinical setting. The current paper aims to review the literature on classic and novel information on the HH – cardiovascular system relationship. Epidemiological data, physiological aspects of the heart compressed by HH, cardiovascular symptoms, electrocardiographic changes, echocardiographic alterations and clinical implications are discussed. Normally, the stomach and the heart are not in direct contact because they are in different cavities, the thorax and the abdomen, respectively. When part of the stomach moves toward the chest through the diaphragm, we say there is a hiatal hernia (HH). Most of the time the HH symptoms are mild and clearly digestive. In severe cases, surgical repair of the HH is required. Even in these circumstances, digestive symptoms continue to be the most frequent. However, some patients present cardiovascular symptoms and few or no digestive symptoms. This easily creates diagnostic confusion, which leads to incorrect treatments and unnecessary expenses. In extreme cases, as seen in giant HH, the degree of cardiovascular involvement is very serious. There are documented cases that have suffered cardiac arrest, arrhythmias of different types and symptoms like classic acute myocardial infarction. It is required that clinical doctors and surgeons are aware that this complication exists. Only with this in mind can a timely diagnosis be achieved. Some emergency measures have been saving, gastric decompression with a tube being the most important. The main mechanism that explains the serious cardiovascular consequences of giant HH is cardiac compression. The dissemination of this knowledge can help save lives. [ABSTRACT FROM AUTHOR]

The evaluation in real-life settings of services for the follow-up and control of hypertensive patients is a complex intervention, which still needs analysis of the roles, tasks, and resources involved in the basic items: patient, healthcare professional, and the interaction between the two. To evaluate the impact of patient-general practitioner (GP) short-messages-based interaction, isolated from other items, on the degree of hypertension control in the follow-up of medium-to-low-risk patients in primary care, a randomized controlled trial has been performed: 38 GPs enrolled 285 hypertensive patients who recorded the results of self-blood-pressure (BP) monitoring, heart rate, and body weight, and completed an optional questionnaire in an identical manner over a six-month period. The telemedicine group (TmG) sent the data to a telemedicine-based system that enabled patient-GP interaction; the control group (CG) recorded the data on paper and could only deliver it to their GP personally in the routine visits. In the TmG, the results were better, but not significantly so, for: 1) degree of hypertension control, in terms of the percentage of uncontrolled hypertensives at the final visit (TmG versus CG: 31.7% versus 35.6%; p = 0.47); 2) reduction in hypertension during follow-up, comparing measurements (performed by a professional) at the initial and final visits of systolic BP (15.5 versus 11.9; p = 0.13) and diastolic BP (9.6 versus 4.4; p = 0.40); and 3) adherence to the protocol within compliance levels of interest in a real-life follow-up service: >50% (84.8% versus 73.3%) and >25% (92.4.8% versus 75.4%) (p = 0.053). Other factors such as average values of self-measured systolic BP, diastolic BP and heart rate, acceptability of the protocol, and median number of consultations and hospital admissions were similar in both groups. Outcomes show that, taken alone, the patient-GP short-messages-based interaction has very little impact on the degree of hypertension control in patients with this profile. In complex interventions, to discriminate the impact of each of its components in isolation will enable us to design an efficient follow-up service, little demanding in terms of healthcare professional dedication, and optimized in other basic aspects.

The authors have designed and developed a telemedicine-based service for the follow-up and monitoring of patients on oral anticoagulant therapy (OAT) that consists of two phases; the first involving self-testing and the second involving guided self-management. To evaluate the first phase of the protocol, a project was conducted with 108 patients, with a mean age of 72.7 years and a mean treatment time at the start of the study of 55.2 months, divided into two groups: telemedicine and control (conventional procedure). The degree of anticoagulation control was similar in the two groups: individual in-range international normalized ratios (59.2% vs 61.1%; p = 0.55) and individual time within target range (65.7% vs 66.4%; p = 0.85) showed no significant differences. The incidence of adverse events—death (5.5% vs 5.5%; p = 1.0), major hemorrhagic complications (0% vs 1.8%; p = 1.0), minor hemorrhagic complications (7.4% vs 3.7%; p = 0.67), and thromboembolism (1.8% vs 3.7%; p = 1.0)—was also similar, with no significant differences. Acceptability of the change, measured in terms of quality of life (SF-12 and Sawicki questionnaires) and anxiety (state-trait anxiety inventory questionnaire) at the beginning and end of the study period was higher in the telemedicine group, with statistically significant improvements in mental component summary (3.6 vs -6.2; p = 0.02), dissatisfaction (-0.8 vs 0.2; p = 0.001), stress (-0.3 vs 0.05; p = 0.03), limitations (-0.2 vs 0.3; p = 0.005), social problems (-0.1 vs 0.3; p = 0.03), and state anxiety (-2.5 vs 2.3; p = 0.04). Parameters related to costs, such as the mean number per patient of office visits due to OAT (1.7 vs 13.8; p < 0.001) and other office visits (10.1 vs 11.5; p = 0.028), were also more favorable in the telemedicine group, as were additional parameters that enabled an exhaustive evaluation of the service. The positive results obtained indicate that the second phase of the trial can be initiated. [ABSTRACT FROM AUTHOR]
