Abstract
Aim The present study was aimed at investigating the prevalence, incidence, progression, and prognosis of degenerative valvular heart disease (DVHD) in permanent residents aged ≥65 years from Guangzhou, China. Methods This was a prospective study based on community population. Over a 3-year span, we conducted repeated questionnaires, blood tests, and echocardiographic and electrocardiogram examinations (2018) of a random sample of initially 3538 subjects. Results The prevalence of DVHD increased with age, average values being 30.6%, 49.2%, and 62.9% in 65-74, 75-84, and ≥85 years of age, respectively. The incidence rate was 1.7%/year. Aortic stenosis was the result of DVHD, and the mean transvalvular pressure gradient increased by 5.6 mmHg/year. The increase of mild aortic stenosis was lower than that of more severe disease, showing a nonlinear development of gradient, but with great individual variations. Mortality was significantly increased in the DVHD group (HR = 2.49). Risk factors for higher mortality included age (χ2 = 1.9, P < 0.05), renal insufficiency (χ2 = 12.5, P < 0.01), atrial fibrillation (χ2 = 12.2, P < 0.01), mitral regurgitation (χ2 = 1.8, P < 0.05), and tricuspid regurgitation (χ2 = 6.7, P < 0.05) in a DVHD population. Conclusions DVHD was highly prevalent among residents in southern China. With the progression of the disease, the mean transvalvular pressure gradient accelerated. DVHD was an independent predictor of death, and the mortality was higher in those with older age, renal insufficiency, atrial fibrillation, mitral regurgitation, and tricuspid regurgitation.

Abstract
INTRODUCTION Aortic stenosis is a common condition among older adults that can be associated with dangerous outcomes, due to both the disease itself and its influence on other conditions. OBJECTIVE This review provides an evidence-based summary of the current emergency department (ED) evaluation and management of aortic stenosis. DISCUSSION Aortic stenosis refers to significant narrowing of the aortic valve and can be caused by calcific disease, congenital causes, or rheumatic valvular disease. Symptoms of advanced disease include angina, dyspnea, and syncope. Patients with these symptoms have a much higher mortality rate than asymptomatic patients. Initial evaluation should include an electrocardiogram, complete blood count, basic metabolic profile, coagulation studies, troponin, brain natriuretic peptide, type and screen, and a chest radiograph. Transthoracic echocardiogram is the test of choice, but point-of-care ultrasound has been found to have good accuracy when a formal echocardiogram is not feasible. Initial management should begin with restoring preload and ensuring a normal heart rate, as both bradycardia and tachycardia can lead to clinical decompensation. For patients with high blood pressure and heart failure symptoms, nitrate agents may be reasonable, but hypotension should be avoided. Dobutamine can increase inotropy. For hypotensive patients, vasopressors should be used at the lowest effective dose. The treatment of choice is valve replacement, but extracorporeal membrane oxygenation and percutaneous balloon dilatation of the aortic valve have been described as temporizing measures. CONCLUSION Aortic stenosis is an important condition that can lead to dangerous outcomes and requires prompt recognition and disease-specific management in the ED.

Abstract
Angiotensin-converting enzyme inhibitors (ACEI) are often used in preventing and treating heart failure due to regurgitant valve disease. The majority of patients with symptomatic rheumatic heart disease (RHD) have significant mitral stenosis (MS) and are denied ACEI therapy, because of the fear of hypotension in the presence of fixed obstruction. The authors assessed the safety and efficacy of ACEI in 109 consecutive patients with RHD and with significant mitral stenosis (mitral valve orifice, MVO <1.5 cm2) and with NYHA class III or IV heart failure symptoms. Mean age was 33.1 ±12 years, systolic blood pressure (BP) was 111 ±10, and diastolic BP was 73 ±8 mm Hg. MS was significant in 100 patients with mitral regurgitation in 46, aortic regurgitation in 19, and pulmonary hypertension in 60 patients. After initial stabilization, enalapril 2.5 mg bid was started in hospital and titrated up to 10 mg bid over 2 weeks. NYHA status, Borg score, and 6-minute walk test were assessed at baseline, and at 1, 2, and 4 weeks. Seventy-nine of the 100 patients who completed the study had severe MS (MVO <1.0 cm2). Enalapril was well tolerated by all study patients without hypotension or worsening of symptoms. NYHA class (3.2 ±0.5 baseline vs 2.3 ±0.5 at 4 weeks, p<0.01) Borg Dyspnea Index (7.6 ±1.3 vs 5.6 ±1.3, p<0.01), and 6-minute walk distance (226 ±106 vs 299 ±127 m, p<0.01) improved significantly with enalapril. Patients with associated regurgitant lesions showed more improvement in exercise capacity (120 ±93 vs 39 ±56 m, p<0.001). Enalapril was well tolerated in patients with RHD with moderate and severe MS. Irrespective of the valve pathology, enalapril improved functional status and exercise capacity with maximum benefit in patients with concomitant regurgitant valvular heart disease.

The arterial blood pressure associated with terminal cardiovascular collapse in critically ill patients: a retrospective cohort study.

[PMID: 25524592 PMCID: PMC4299308 DOI: 10.1186/s13054-014-0719-2] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/06/2014] [Accepted: 12/11/2014] [Indexed: 01/22/2023]
Abstract
Introduction Liberal and overaggressive use of vasopressors during the initial period of shock resuscitation may compromise organ perfusion and worsen outcome. When transiently applying the concept of permissive hypotension, it would be helpful to know at which arterial blood pressure terminal cardiovascular collapse occurs. Methods In this retrospective cohort study, we aimed to identify the arterial blood pressure associated with terminal cardiovascular collapse in 140 patients who died in the intensive care unit while being invasively monitored. Demographic data, co-morbid conditions and clinical data at admission and during the 24 hours before and at the time of terminal cardiovascular collapse were collected. The systolic, mean and diastolic arterial blood pressures immediately before terminal cardiovascular collapse were documented. Terminal cardiovascular collapse was defined as an abrupt (<5 minutes) and exponential decrease in heart rate (>50% compared to preceding values) followed by cardiac arrest. Results The mean ± standard deviation (SD) values of the systolic, mean and diastolic arterial blood pressures associated with terminal cardiovascular collapse were 47 ± 12 mmHg, 35 ± 11 mmHg and 29 ± 9 mmHg, respectively. Patients with congestive heart failure (39 ± 13 mmHg versus 34 ± 10 mmHg; P = 0.04), left main stem stenosis (39 ± 11 mmHg versus 34 ± 11 mmHg; P = 0.03) or acute right heart failure (39 ± 13 mmHg versus 34 ± 10 mmHg; P = 0.03) had higher arterial blood pressures than patients without these risk factors. Patients with severe valvular aortic stenosis had the highest arterial blood pressures associated with terminal cardiovascular collapse (systolic, 60 ± 20 mmHg; mean, 46 ± 12 mmHg; diastolic, 36 ± 10 mmHg), but this difference was not significant. Patients with sepsis and patients exposed to sedatives or opioids during the terminal phase exhibited lower arterial blood pressures than patients without sepsis or administration of such drugs. Conclusions The arterial blood pressure associated with terminal cardiovascular collapse in critically ill patients was very low and varied with individual co-morbid conditions (for example, congestive heart failure, left main stem stenosis, severe valvular aortic stenosis, acute right heart failure), drug exposure (for example, sedatives or opioids) and the type of acute illness (for example, sepsis).

Abstract
BACKGROUND Animal models have demonstrated a benefit of angiotensin-converting enzyme inhibitors (ACEI) in experimental aortic stenosis (AS), and intravenous nitroprusside has shown hemodynamic improvements in AS with left ventricular (LV) dysfunction. Although routinely used in most heart failure situations, ACEI are avoided in AS because of the risk of hypotension. We aimed to determine the clinical tolerance and efficacy of the ACEI enalapril in the setting of symptomatic severe AS. METHODS Patients with symptomatic severe AS were enrolled in a randomized, double-blinded, controlled trial to enalapril or placebo arms after initial stabilization. Standard antifailure medications were continued. Enalapril was started at 2.5 mg bid and increased to 10 mg bid. The primary end points were development of hypotension and improvements in Borg dyspnea index and 6-minute walk distance at 1 month. Secondary end points were minor ACEI intolerance, cough, presyncope, improvement in New York Heart Association class, and echocardiographic parameters. RESULTS Fifty-six patients were enrolled (37 in the enalapril arm and 19 in the placebo arm). Enalapril was tolerated without hypotension or syncope when LV systolic function was preserved. Three of 5 patients with LV dysfunction and congestive heart failure had hypotension and were withdrawn. Patients who tolerated enalapril (n = 34) demonstrated significant improvement in NYHA class, Borg index (5.4 +/- 1.2 vs 5.6 +/- 1.7, P =.03), and 6-minute walk distance (402 +/- 150 vs 376 +/- 174, P =.003) compared with control subjects. Within the enalapril group, patients with associated regurgitant lesions improved the most. CONCLUSIONS ACEI are well tolerated in symptomatic patients with severe AS. Patients with congestive heart failure with LV dysfunction and low normal blood pressure are prone to have hypotension. Enalapril significantly improves effort tolerance and reduces dyspnea in symptomatic AS.

Abstract
OBJECTIVES We sought to determine the association of age with the change in quality of life (QOL) after valve surgery. BACKGROUND Improvement in QOL is one of the principal goals of valve surgery. These procedures are being done with increasing frequency for older patients. METHODS We prospectively studied 148 patients with aortic valve procedures and 72 patients with mitral valve procedures. Patients' QOL was measured at baseline and at 18 months using the Medical Outcomes Trust Short Form 36-Item (SF-36) Health Survey (response rate 90%). The association of age with change in QOL was measured by multiple regression analysis and based on two meta-scores of the SF-36: the Mental Component Summary (MCS) and the Physical Component Summary (PCS). RESULTS Overall improvement in most domains of the SF-36, including the MCS and the PCS scores, was substantial. Improvement in the MCS score was not influenced by age in either aortic (0.09 score point improvement per 10-year age increments; p = 0.9) or mitral (0.90 score point improvement per 10-year age increments; p = 0.3) patients. Similarly, improvement in the PCS score did not vary by age in aortic patients (-1.00 score points per 10-year age increments; p = 0.2) and only slightly varied by age in mitral patients (-1.90 score points per 10-year age increments, p = 0.02). In the latter, despite statistical significance, the association was not substantial or clinically important. CONCLUSIONS Among patients referred for cardiac valve surgery, age does not appear to limit the QOL benefits of surgery.

Abstract
BACKGROUND Vasodilators are considered to be contraindicated in patients with severe aortic stenosis because of concern that they may precipitate life-threatening hypotension. However, vasodilators such as nitroprusside may improve myocardial performance if peripheral vasoconstriction is contributing to afterload. METHODS We determined the response to intravenous nitroprusside in 25 patients with severe aortic stenosis and left ventricular systolic dysfunction. Patients were included in the study if they had been admitted to the intensive care unit for invasive hemodynamic monitoring of heart failure and if they had a depressed ejection fraction (<or=0.35), severe aortic stenosis (aortic-valve area, <or=1 cm2), and a depressed cardiac index (<or=2.2 liters per minute per square meter). Patients were excluded if they had hypotension, defined as either the need for intravenous inotropic or pressor agents or a low mean systemic arterial pressure (<60 mm Hg). Patients were enrolled irrespective of other, coexisting valve disease or coronary artery disease. RESULTS At base line, the mean (+/-SD) ejection fraction was 0.21+/-0.08; the aortic-valve area was 0.6+/-0.2 cm2, with peak and mean gradients of 65+/-37 and 39+/-23 mm Hg, respectively; and the cardiac index was 1.60+/-0.35 liters per minute per square meter. After six hours of therapy with nitroprusside (at which time the dose had been increased to a mean of 103+/-67 microg per minute), the cardiac index had increased to 2.22+/-0.44 liters per minute per square meter (P<0.001 for the comparison with base line). After 24 hours of nitroprusside infusion (dose, 128+/-96 microg per minute), the cardiac index had increased further, to 2.52+/-0.55 liters per minute per square meter (P<0.001 for the comparison with base line). Nitroprusside was well tolerated and had minimal side effects. CONCLUSIONS Nitroprusside rapidly and markedly improves cardiac function in patients with decompensated heart failure due to severe left ventricular systolic dysfunction and severe aortic stenosis. It provides a safe and effective bridge to aortic-valve replacement or oral vasodilator therapy in these critically ill patients.

Abstract
Mitral valve stenosis can lead to a range of symptoms that affect daily life. As many of the people with this problem are elderly, the difficulties resulting from age can be exacerbated by illness. A pilot descriptive study was designed to examine the differences in anxiety, depression and functional capacity in women with mitral valve stenosis who were aged over 60 years when compared to a similar group of volunteers who did not have any cardiac disease. Measurement was undertaken using the Hospital Anxiety and Depression scale, the SF-36 Health Status questionnaire and the Functional Limitations Profile. Forty women were recruited to the study: 20 women with mitral valve stenosis and 20 volunteers. Each person was asked to complete the three questionnaires on one occasion only. Non-parametric statistics were used for analysis. Patients fared worse than volunteers with significant differences between groups in respect of anxiety (P = 0.03), depression (P = 0.02) and overall function (P < 0.001), but not in physical (P = 0.52) or mental health (P = 0.32). Future research could focus on strategies that would help alleviate anxiety and depression and improve functional capacity in older women with mitral valve stenosis.
