The Effect of Submaximal Exercise on Jugular Venous Pulse Assessed by a Wearable Cervical Plethysmography System. Diagnostics (Basel) 2022; 12:diagnostics12102407. [PMID: 36292096 PMCID: PMC9600745 DOI: 10.3390/diagnostics12102407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/26/2022] [Accepted: 09/29/2022] [Indexed: 11/18/2022] Open
Abstract
The jugular venous pulse (JVP) is a one of the crucial parameters of efficient cardiovascular function. Nowadays, limited data are available regarding the response of JVP to exercise because of its complex and/or invasive assessment procedure. The aim of the present work is to test the feasibility of a non-invasive JVP plethysmography system to monitor different submaximal exercise condition. Twenty (20) healthy subjects (13M/7F mean age 25 ± 3, BMI 21 ± 2) underwent cervical strain-gauge plethysmography, acquired synchronously with the electrocardiogram, while they were carrying out different activities: stand supine, upright, and during the execution of aerobic exercise (2 km walking test) and leg-press machine exercise (submaximal 6 RM test). Peaks a and x of the JVP waveform were investigated since they reflect the volume of cardiac filling. To this aim, the Δax parameter was introduced, representing the amplitude differences between a and x peaks. Significant differences in the values of a, x, and Δax were found between static and exercise conditions (p < 0.0001, p < 0.0001, p < 0.0001), respectively. Particularly, the Δax value for the leg press was approximately three times higher than the supine, and during walking was even nine times higher. The exercise monitoring by means of the novel JVP plethysmography system is feasible during submaximal exercise, and it provides additional parameters on cardiac filling and cerebral venous drainage to the widely used heartbeat rate value.

Jugular Venous Pressure Response to Inspiration for Risk Assessment of Heart Failure. Am J Cardiol 2022; 170:71-75. [PMID: 35277252 DOI: 10.1016/j.amjcard.2022.01.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 01/01/2022] [Accepted: 01/17/2022] [Indexed: 11/23/2022]
Abstract
Simplifying jugular venous pressure (JVP), visibility of the right internal jugular vein above the right clavicle in the sitting position, has been proposed in the management of heart failure (HF) because of its convenience. However, this method may be undervalued for the detection of mildly to moderately increased JVP. Increased JVP on inspiration, known as Kussmaul sign, may be a useful physical finding in this condition. This study consisted of 138 patients who were admitted for the management of HF. Using this simple method, JVP was assessed at rest in the sitting position before discharge; its response to inspiration was also examined if no high JVP was noted at rest. The primary outcome was a composite of cardiac death and hospitalization for worsening HF. Among all the patients, 16 patients (12%) had high JVP at rest and another 16 patients (12%) had high JVP not at rest but on inspiration. During a follow-up period of 249 ± 182 days, a primary outcome event occurred in 63 patients (46%). The incidence of adverse cardiac events was higher in patients with a high JVP at rest (69%; hazard ratio 3.31, 95% confidence interval 1.64 to 6.67, p = 0.0009) and in patients with a high JVP on inspiration (56%; hazard ratio 2.18, 95% confidence interval 1.02 to 4.63, p = 0.043) than in patients without a high JVP in both conditions (41%). In conclusion, a high JVP not only at rest but also on inspiration was associated with a poor prognosis. The response of JVP to inspiration using this simple technique of physical examination may be a new approach in the management of HF.
