Orthostatic Stress Test

Dalam praktek klinis kedokteran gigi, seringkali pasien datang dengan tekanan darah yang tinggi meskipun ia tidak memiliki riwayat hipertensi sebelumnya. Pada kondisi ini, tingginya tekanan darah seringkali dipengaruhi oleh tingkat kecemasan pasien yang nantinya akan mempengaruhi sistem saraf otonom. Akupunktur merupakan suatu metode pengobatan dengan penusukan jarum tanpa memasukkan bahan kimia ke dalam tubuh pasien. Penelitian ini bertujuan untuk mengkaji pengaruh penusukan tunggal titik akupunktur telinga Ciao Kan terhadap tekanan darah dan frekuensi denyut jantung. Hipotesis yang diajukan adalah penusukan tunggal titik akupunktur telinga Ciao Kan menyebabkan terjadinya penurunan tekanan darah dan frekuensi denyut jantung. Penelitian ini merupakan penelitian eksperimental dengan mempergunakan rancangan penelitian pre-post test design. Subjek penelitian adalah laki-laki berusia 25–35 tahun dengan tekanan sistolik lebih atau sama dengan 130 mmHg yang memenuhi kriteria inklusi dan eksklusi. Subjek menjalani orthostatic stress test, penusukan titik akupunktur telinga Ciao Kan, pengukuran tekanan darah dan frekuensi denyut jantung. Metode statistik yang dipergunakan adalah uji t, uji korelasi Pearson, dan uji ANOVA satu jalur. Uji t dilakukan pada data yang telah ditransformasi. Tekanan sistolik turun signifikan pada subyek penelitian selama perlakuan (p<0,05) namun kemudian naik kembali. Frekuensi denyut jantung juga mengalami penurunan signifikan (p<0,05) selama perlakuan dan naik kembali. Uji korelasi Pearson dilakukan untuk melihat korelasi antara tekanan arteri rata-rata dengan frekuensi denyut jantung. Hasil uji korelasi menunjukkan adanya korelasi positif antara tekanan arteri rata-rata dan frekuensi denyut jantung (r =0,373). Uji ANOVA satu jalur menunjukkan tidak adanya perbedaan nilai tekanan sistolik, tekanan diastolik, tekanan arteri rata-rata, dan frekuensi denyut jantung antar kelompok dengan respon terhadap orthostatic stress test normal, hipertonus, maupun hipotonus (p >0,05). Dengan demikian dapat dikatakan bahwa penusukan tunggal titik akupunktur telinga Ciao Kan menyebabkan terjadinya penurunan tekanan darah dan frekuensi denyut jantung. The Effect of Single Acupuncture on Ciao Kan Ear Acupoint on Blood Pressure and Heart Rate In dental clinical practice. Patient sometime come with high blood pressure even though they have no history of hypertension. In this condition, high blood pressure could be influenced by anxiety that will have an effect on autonomic nerve system. Acupuncture is a healing method with needle puncture without giving chemical substance to patient’s body. This research aimed at evaluating the effect of a single acupuncture on Ciao Kan ear acupoint on blood pressure and heart rate. Hypothesis of this research was single acupuncture on Ciao Kan ear acupoint could decrease blood pressure and heart rate. This was a pre-post test design experiment. Subjects were men, 25 – 35 years old with systolic blood pressure equal or more than 130 mmHg who met the inclusion and exclusion criteria. Subject did orthostatic stress test, acupuncture on Ciao Kan ear acupoint, blood pressure measurement, and heart rate measurement. T test was done on the transformed data. Systolic blood pressure decreased significantly (p < 0.05) during acupuncture and then increased afterward. Heart rates also decreased significantly (p < 0.05) during acupuncture and then increased afterward. Pearson correlation test was done to see the correlation between mean arterial pressure and heart rate. The results showed a positive correlation between mean arterial pressure and heart rate (r = 0.373). One way ANOVA showed no systolic, diastolic, mean arterial pressure, and heart rate differences between groups in response to orthostatic stress test normal, hyper tone, or hypo tone (p > 0.05). It could be said that single acupuncture on Ciao Kan ear acupoint could decrease blood pressure and heart rate.

Endurance running is an exercise practiced by athletes in many sports. Being benefi cial to health, it is also under-taken by a great number of non-athletic individuals. Rigorous endurance training frequently induces symmetric (i. e. both ventricular chamber dilation and wall thickening) myocardial hypertrophy, which is a physiological adapta-tion. Although distance running is a sport associated with haemodynamic volume rather than pressure overload, in addition to enlarged cardiac output, systolic arterial blood pressure also considerably increases during running. The extent of the cardiac hypertrophy was shown to be correlated with peak blood pressure measured during laboratory exercise. However, the predominant type of myocardial hypertrophy (the ratio between the myocardial wall thickness and chamber size) in endurance runners remains contradictory, and the majority of the responsible factors are still to be determined. The aim of this study was to determine possible correlations between post-run systolic blood pressure and myocardial hypertrophy in endurance runners.Standard transthoracic two-dimensional M-mode echocardiography was performed in white adult male distance runners (n = 49) of national level within four weeks of treadmill testing, which was a non-continuous incremental exercise test employed for the determination of the heart rate as well as post-exertional systolic blood pressure re-sponse. Runners’ training volume (evaluated as the average number of hours per week spent training averaged over the past four weeks) correlated (p < 0.05) positively with the left ventricular (LV) wall thickness but not with the cavity size or LV mass (p > 0.05). Training volume also positively correlated with systolic blood pressure response to exercise (p < 0.05), but negatively with submaximal exercise heart rate (p < 0.01). Post-run systolic blood pressure correlated positively with LV wall thickness and LV concentricity (namely, the ratio between the myocardial wall thick-ness and chamber size) (p < 0.05), but no signifi cant correlation of any of the LV size parameters with resting heart rate, blood pressure, or systolic blood pressure in 2 to 4 min during the recovery period was revealed. Submaximal and maximal heart rate correlated signifi cantly and negatively with LV wall thickness, LV mass, and systolic blood pressure measured immediately after running (p < 0.05).Training volume and post-run systolic blood pressure have been found to correlate positively with LV wall thickness and concentricity in white adult male distance runners. Negative correlation of exercise heart rate has been found with the post-exercise systolic blood pressure, LV wall thickness, and LV mass.Keywords: myocardial hypertrophy, pressure overload, echocardiography, athlete’s heart.

Abstract Background: Both cerebral vascular disorders and cognitive decline increase in incidence with age. The role of cerebral vascular disease and hemodynamic changes in the development of cognitive deficits is controversial. The objective of this study was to assess cardiovascular response during cardiac stress testing in neurologically asymptomatic individuals who developed cognitive impairment several years after the cardiac stress testing.Methods: This is a retrospective cohort study of patients who underwent cardiac stress testing between January 2001 and December 2010. Patients were followed up until May 2015 and we selected those who developed cognitive dysfunction including dementia, mild cognitive impairment and subjective cognitive decline, after the stress test. Heart rate and blood pressure both at rest and at peak exercise and the mean R-R interval at rest were recorded. For each patient who developed cognitive impairment, we selected one matched control who did not show cognitive decline by the end of the follow-up period.Results: From this cohort of 7224 patients, 371 developed cognitive impairment; of these, 186 (124 men) met the inclusion criteria and 186 of the other patients were selected as matched controls. During follow-up, cognitive impairment appeared 6.2 ± 4.7 years after the cardiac stress test. These patients who subsequently developed cognitive impairment had significantly lower at-rest systolic, diastolic and mean blood pressure than controls (p<0.05). Further, compared with controls, their maximum heart rate was significantly higher at peak exercise and both systolic and diastolic blood pressures increased significantly more during exercise. Conclusion: The results from this study suggest that differences in cardiovascular response to stress are present in the preclinical phase of cognitive decline, serving as a potential risk factor for cognitive impairment. These findings challenge the potential use of blood pressure and heart rate variability at rest and during cardiac stress assessment as a risk factor for cognitive impairment.

1. The β-adrenoreceptor-blocking effects of pindolol were compared with those of propranolol and a placebo in a double-blind cross-over trial involving nine hypertensive African patients. 2. Heart rate, systolic blood pressure and diastolic blood pressure were measured at rest and immediately after exercise before and at intervals up to 6 h after oral administration of the drugs. In addition, plasma pindolol and propranolol concentrations were determined at the same intervals. 3. Pindolol diminished systolic blood pressure at rest and after exercise and antagonized exercise-induced tachycardia, but had no effect on resting heart rate. Propranolol diminished systolic blood pressure predominantly after exercise and reduced both resting and exercise heart rate. Both drugs had no effect on diastolic pressure. 4. The mean plasma concentration reached a peak at 2 h for each drug and this coincided with the interval at which maximal β-adrenoreceptor-blocking effect was observed.

We tested whether the Arg389Gly and Ser49Gly polymorphisms of the β1-adrenergic receptor gene ADRB1 and the T393C polymorphism of the G protein α-subunit gene GNAS1 modulate heart rate (HR) and blood pressure responses during an exercise stress test. The study population comprised 890 participants (563 men and 327 women, mean age 58.1 ± 12.6 yr) of the Finnish Cardiovascular Study. Their HR, systolic (SAP), and diastolic arterial pressures (DAP) at rest, during exercise, and 4 min after the test were measured and analyzed by repeated-measurement ANOVA (RANOVA). Genotypes were detected by TaqMan 5′ nuclease assay. In all subjects, and in men and women separately, the T393C of GNAS1 was the only polymorphism with genotype × time interaction in HR over the three study phases ( P = 0.04, RANOVA). None of the polymorphisms presented genotype × time interaction in SAP or DAP responses ( P > 0.10, RANOVA). In all subjects at rest, the Ser49Gly polymorphism of ADRB1 tended ( P = 0.06, ANOVA) to differentiate HR. Arg389Gly polymorphism of ADRB1 affected maximal SAP during exercise ( P = 0.04, ANOVA) and the change in SAP from rest to maximal ( P = 0.03, ANOVA). Arg389 homozygotes, particularly men, were less likely to have ventricular extrasystoles during the exercise (odds ratio = 0.68, 95% confidence interval = 0.51–0.91, P = 0.009, and odds ratio = 0.60, 95% confidence interval = 0.42–0.86, P = 0.006, respectively) than did Gly389 carriers. In conclusion, polymorphisms examined appear to have modulatory effects on hemodynamics in a clinical exercise test setting. However, the effects in absolute numbers were minor and clinically possibly insignificant.
