Value of ejection fraction/velocity ratio in the prognostic stratification of patients with asymptomatic aortic valve stenosis.

BACKGROUND: The ejection fraction/velocity ratio (EFVR) is a simple function-corrected index of aortic stenosis severity with a good correlation with aortic valve area measured using the Gorlin formula at cardiac catheterization. It is calculated by dividing left ventricular ejection fraction (LVEF) to 4 × (peak jet velocity)2 . OBJECTIVE: Our aim was to evaluate the value of EFVR in predicting adverse events in patients with asymptomatic aortic stenosis. METHODS: We analyzed the clinical and echocardiographic data of 216 asymptomatic patients with at least moderate aortic stenosis (AVA ≤ 1.5 cm2 ). The primary end-point was cardiovascular death or aortic valve replacement. RESULTS: There were 119 (55%) men and mean age was 68 ± 10 years. The mean follow-up time was 4.2 ± 1.6 years (median 4.3 years). During follow-up, the composite end-point of death or aortic valve replacement was reached in 105 patients (49%). Using multivariate Cox regression analysis, EFVR and valvulo-arterial impedance emerged as independent variables associated with outcome (P < 0.001 and P = 0.001, respectively). In the subgroup of patients with severe aortic stenosis (AVA < 1 cm2 ), EFVR ≤ 0.9 was associated with an increased hazard ratio for the composite end-point of mortality and aortic valve replacement (HR 2.14, 95% CI: 1.15-4.0, P = 0.017), even after adjusting for aortic valve area. CONCLUSIONS: In patients with asymptomatic moderate to severe aortic stenosis, EFVR is useful for risk stratification. Our results suggest that incorporating EFVR in the evaluation of patients with asymptomatic aortic stenosis might help identify those who are most likely to benefit from early elective aortic replacement.

New classification of geometric ventricular patterns in severe aortic stenosis: Could it be clinically useful?

BACKGROUND: In severe aortic stenosis, different left ventricle (LV) remodeling patterns as a response to pressure overload have distinct hemodynamic profiles, cardiac function, and outcomes. The most common classification considers LV relative wall thickness and LV mass index to create 4 different groups. A new classification including also end-diastolic volume index has been recently proposed. AIM: To describe the prevalence of the newly identified remodeling patterns in patients with severe aortic stenosis and to evaluate their clinical relevance according to symptoms. METHODS: We analyzed 286 consecutive patients with isolated severe aortic stenosis. Current guidelines were used for echocardiographic evaluation. Symptoms were defined as the presence of angina, syncope, or NYHA class III-IV. RESULTS: The mean age was 75 ± 9 years, 156 patients (54%) were men, while 158 (55%) were symptomatic. According to the new classification, the most frequent remodeling pattern was concentric hypertrophy (57.3%), followed by mixed (18.9%) and dilated hypertrophy (8.4%). There were no patients with eccentric remodeling; only 4 patients had a normalLV geometry. Symptomatic patients showed significantly more mixed hypertrophy (P < .05), while the difference regarding the prevalence of the other patterns was not statistically significant. When we analyzed the distribution of the classic 4 patterns stratified by the presence of symptoms, however, we did not find a significant difference (P = .157). CONCLUSIONS: The new classification had refined the description of different cardiac geometric phenotypes that develop as a response to pressure overload. It might be superior to the classic 4 patterns in terms of association with symptoms.

Differences in left ventricular geometry in hypertensive African-Europeans and Caucasian patients.

BACKGROUND: There are data showing race-related differences regarding left ventricular (LV) geometry in hypertensive patients. Several authors reported that concentric remodeling is the most common remodeling pattern in hypertensive African-Americans, and this pattern may be related to prognosis. There is little information about the LV remodeling patterns in hypertensive Africans that migrated to Europe, which might have different distributions from those seen in African-Americans. The aim our study was to describe the prevalence of LV remodeling patterns in hypertensive African-Europeans and to compare it with that of hypertensive Caucasians. METHODS: This is a descriptive study that included 135 consecutive treated hypertensive African-Europeans and 128 hypertensive Caucasians. Patients were examined by transthoracic echocardiography and categorized into the four classic geometric patterns according to LV mass index (LVMi) and relative wall thickness (RWT). RESULTS: The mean age and gender distribution were similar in the 2 groups. Caucasians had significantly higher body mass index, LV diastolic and systolic diameters, while African-Europeans had higher RWT and interventricular septum thickness. No differences in LVMi was found. In the African-European group, the prevalence of normal pattern, concentric remodeling, concentric hypertrophy and eccentric hypertrophy were 13%, 36%, 45% and 6% respectively, while in Caucasians they were 21%, 33%, 34% and 12%, respectively. African-Europeans had a higher prevalence of concentric remodeling and hypertrophy compared to Caucasians (81% vs. 67%, p = .005). CONCLUSIONS: This study shows important differences in LV geometry between treated African-European and Caucasian hypertensive patients. Also, African-Europeans may have slightly different characteristics compared to African-Americans.

Heterogeneity of clinical presentation in Tako-Tsubo syndromes: the prevalence of normal segmental wall motion and normal ECG pattern.

AIM: The aim of this study is to report the heterogeneity of clinical presentation in Tako-Tsubo syndrome (TTS), including a significant prevalence of normal ECG and echocardiographic patterns in a series of consecutive patients from a single center. METHODS AND RESULTS: From our database we selected a total of 168 cases of TTS. A total of 140 of these (Group A); 14 men (10%), mean age 60.3 years, range 39-87; 126 women (90%), mean age 66.1 years, range 43-93; matched the following reported criteria: typical stenocardic pain immediately following an emotional acute stress, or acute medical or surgical event within the preceding 12 h; acute rise and fall of troponin release; absence of significant coronary disease at coronary angiography. ECG findings at presentation ranged from T wave abnormalities (41 cases, 29.3%) to ST elevation (52 cases, 37.1%) and ST depression (11 cases, 7.9%), whereas in 36 cases (25.7%) the ECG was normal. Echocardiography at presentation showed akinesia of the total apical or medium-apical segments in 74 patients (53%), whereas it showed akinesia of left ventricular wall segments in other locations in 30 patients (21%) and even normal regional wall motion and thickening in 36 patients (26%). We described also a series of 13 female patients (mean age 70.2 years; age range 45-85 years) (Group B) who did not complain of chest pain at presentation, but showed a classical Tako-Tsubo evolution of wall motion abnormalities at echocardiography. Finally we selected 15 female patients (mean age 69.3 years; age range 49-89 years) (Group C) who formally did not report acute stress immediately preceding their presentation to the hospital for chest pain. They showed a classical Tako-Tsubo evolution of wall motion abnormalities at echocardiography and only one case of normal ECG pattern at presentation. CONCLUSION: In this series of acute TTS, a wide variability of ECG and echocardiographic patterns are observed, ranging from ST elevation with coexisting segmental wall motion abnormalities of the typical TTS to a clinical presentation characterized by normal ECG and normal segmental wall motion pattern.

Clinical and echocardiographic predictors of long-term outcome of a large cohort of patients with bicuspid aortic valve.

BACKGROUND AND OBJECTIVES: Bicuspid aortic valve (BAV) disease is the most common congenital cardiac malformation. The aim of the present article is to determine clinical and echocardiographic prognostic factors and provide a predictive model of outcome of a large cohort of patients with BAV. METHODS: We retrospectively enrolled 337 patients consecutively assessed for echocardiography at our Cardiology Department from 1993 to 2014. We considered aortic valve replacement, aortic surgery and cardiovascular death as a clinical combined end-point. Predictors of outcome were determined by Cox regression. RESULTS: Mean age was 29.2 ±â€Š19.8 years, median 27.1 years. A total of 38.4% patients presented a history of hypertension. Mean duration of follow-up was 8.4 ±â€Š6.1 years, range 0-21 years. A total of 73 patients underwent aortic valve replacement and/or aortic surgery during follow-up. Age at surgery was 45.2 ±â€Š15.6 years. Seven patients died because of cardiovascular causes. At multivariate analysis, baseline clinical predictors were history of hypertension [hazard ratio (HR) 2.289, 95% confidence interval (CI) 1.350-3.881, P = 0.002], larger ascending aortic diameter (HR 2.537, 95% CI 1.888-3.410, P < 0.001), moderate-to-severe aortic regurgitation (HR 2.266, 95% CI 1.402-3.661, P = 0.001) and moderate-to-severe aortic stenosis (HR 2.807, 95% CI 1.476-5.338, P = 0.002). A predictive model was created by integrating these four independent covariates. It allows the calculation of calculate a risk score for each patient, which helps better tailor appropriate treatment in BAV patients. CONCLUSION: At enrolment, history of hypertension, a wider aortic diameter, moderate-to-severe aortic regurgitation and aortic stenosis were independently correlated to combined end-point. Long-term follow-up showed low cardiovascular mortality (2.1%) and a high prevalence of cardiac surgery (21.6%).

Effect of statins on the progression of bioprosthetic aortic valve degeneration.

To date, there is no proved medical therapy able to significantly reduce the degenerative process of biologic prosthetic aortic valves. It has recently been suggested that statins may reduce the progression of native aortic valve stenosis. We examined the effect of statin treatment on bioprosthetic aortic valve degeneration and found a beneficial effect of statins in slowing bioprosthetic degeneration.

Left atrium remodeling after acute myocardial infarction (results of the GISSI-3 Echo Substudy).

To evaluate the existence, timing, and determinants of post-infarction left atrial remodeling, we studied a subgroup of 514 patients from the Third Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico Echo Substudy who underwent 4 serial 2-dimensional echocardiograms up to 6 months after acute myocardial infarction. This study is the first to demonstrate, in a large series of patients, the existence of early and late left atrial remodeling after low-risk acute myocardial infarction and the relation of left atrial remodeling to left ventricular remodeling.

Modifications of Oxygen Saturation During Transesophageal Echocardiography.

The present study was designed: (1) to establish the effects of transesophageal echocardiography (TEE) on arterial oxygen saturation (SAO(2)%); (2) to verify the possible clinical consequences of this phenomenon; and (3) to study the possibility of predicting modifications of SAO(2)% by clinical or hemodynamic variables or by specific factors related to the TEE procedure. We prospectively studied 116 unselected patients, aged 61 +/- 12 years, who underwent diagnostic TEE for various clinical indications. Thirty-seven patients had mitral valve disease, 19 aortic valve disease, 14 combined mitroaortic disease, 8 congenital heart disease, and 38 other cardiovascular diseases. Eight patients were affected by chronic obstructive pulmonary disease. Ninety-seven patients were sedated by 4 +/- 2 mg of diazepam IV SAO(2)% (5-min average) (Ohmeda Biox 3700 pulse oxymeter finger probe), heart rate (HR), and blood pressure (BP) were considered during baseline transthoracic examination, after pharmacological sedation but before the introduction of the probe, and finally during TEE. Neither clinical complications nor major arrhythmias were observed. Baseline SAO(2)%, HR and BP were, respectively, 93.6 +/- 3.3%, 76 +/- 14 beats/min, and 129 +/- 20/75 +/- 10 mmHg. Pharmacological sedation did not modify SAO(2)%, HR, and BP (P > 0.1). During TEE a small but significant reduction in SAO(2)% by an average of 1.2 +/- 3.2% was observed (P < 0.005), as well as a small and significant increase in HR by an average of 3 +/- 10 beats/min (P < 0.01). BP did not change significantly (P > 0.1 for both systolic and diastolic). The changes of SAO(2)% and HR were not interrelated and were not related to the duration of the procedure and to any of the clinical and hemodynamic variables taken into consideration. TEE can induce a small but significant drop in SAO(2)% and a small increase in HR even without any clinical relevance. No clinical or hemodynamic variable or specific factors related to the TEE procedure were related to these changes.

Reliability of new and old Doppler echocardiographic indexes of the severity of aortic stenosis in patients with a low cardiac output.

BACKGROUND: In addition to the conventional "flow-corrected" parameters (continuity equation and aortic valve resistance), new and simpler Doppler echocardiographic indexes of the severity of aortic stenosis have recently been introduced. These measures can be classified as "function-corrected" indexes (fractional shortening-velocity ratio and ejection fraction-velocity ratio) and "pressure-corrected" indexes (percent stroke work loss). Little information however is available about the diagnostic accuracy of each of these parameters in identifying patients with severe aortic stenosis in low-flow states, in which the diagnosis and clinical decision-making are more difficult and challenging. METHODS: We analyzed 161 patients with aortic stenosis (96 males, 65 females, mean age 68 +/- 9 years) and a low cardiac output (thermodilution cardiac index < or = 2.5 l/min/m2). All patients underwent both cardiac catheterization and echocardiography within 48 hours one of the other. The invasive Gorlin valve area was used as gold standard (severe aortic stenosis = Gorlin < or = 0.8 cm2). Echocardiographic indexes were assessed by an investigator who was unaware of the hemodynamic findings. RESULTS: The mean Gorlin aortic valve area was 0.7 +/- 0.3 cm2; cardiac catheterization allowed the identification of 129 patients with severe aortic stenosis and of 32 with mild-to-moderate aortic stenosis. The diagnostic accuracy of the Doppler gradient alone was low (sensitivity 55%). The best linear correlation with the Gorlin value was found using the "function-corrected" ejection fraction-velocity ratio (r = 0.85). Similarly, the best combination of sensitivity and specificity in identifying patients with severe aortic stenosis, as assessed by cardiac catheterization, was observed using the ejection fraction-velocity ratio (sensitivity 87%, specificity 88%). CONCLUSIONS: In patients with aortic stenosis and a low cardiac output, the "function-corrected" ejection fraction-velocity ratio offers the better diagnostic accuracy, as compared with the cardiac catheterization valve area calculation.

Transesophageal electrical cardioversion of persistent atrial fibrillation: a new approach for an old technology.

BACKGROUND: Low energy intracardiac cardioversion may be considered the elective, alternative method for the acute restoration of sinus rhythm when direct current cardioversion fails or is contraindicated. Transesophageal cardioversion is a further alternative method for the recovery of sinus rhythm and obviates the potential complications of the low energy intracardiac cardioversion venous approach. METHODS: The present prospective study including 30 patients (21 males, 9 females, mean age 65.1 years, range 52-76 years), with persistent atrial fibrillation (mean duration 4.3 months), was undertaken in order to further evaluate, with regard to transesophageal cardioversion: 1) the acute efficacy, 2) the patient acceptance of the procedure, 3) the preferable choice among direct current cardioversion, low energy intracardiac cardioversion and transesophageal cardioversion, 4) the time required to perform the procedure, 5) the incidence of complications, and 6) the persistence of sinus rhythm after 1 month. RESULTS: Sinus rhythm was acutely restored in 29 patients (96.7%). Discomfort induced by the electrical shock was minimal or mild in most patients (75.8%). Transesophageal cardioversion was usually preferred by patients who had been previously submitted to direct current cardioversion or low energy intracardiac cardioversion. The mean total time required to perform the procedure was 107.9 min. No complications related to the procedure occurred. In spite of adequate pharmacological prophylaxis of atrial fibrillation only 41.4% of patients were in sinus rhythm 1 month after successful transesophageal cardioversion. CONCLUSIONS: Transesophageal cardioversion may be considered a very effective, well accepted and non-time consuming procedure for the short-term restoration of sinus rhythm. The incidence of complications is low.

Usefulness of exercise test in selected patients coming to the emergency department for acute chest pain.

BACKGROUND: The management of patients with acute chest pain is a common and difficult challenge for clinicians. In our emergency department (ED) a systematic protocol that involves the use of the exercise test for the management of patients with chest pain of suspected cardiac origin is presently running. The aim of the present study was to evaluate the feasibility of such a test in this setting, in terms of the safety and satisfactory follow-up of these patients discharged home. METHODS: Patients with chest pain lasting < or = 24 hours, aged > 18 years, without a history of trauma or of any other evident medical cause of chest pain and without high-risk characteristics were included in the present study. These patients, defined as low-risk patients for acute coronary events on admission, were evaluated in the ED area and submitted to serial ECG and blood sampling for the determination of the creatine kinase-MB mass and troponin I serum levels on admission and at 6 and 12 hours after admission. A symptom-limited maximal exercise was performed in the patients with a negative clinical observation and typical chest pain or atypical chest pain but multiple coronary risk factors. RESULTS: In the year 2000, 1370 patients were evaluated in the ED for chest pain. In 150 (11%) an exercise test was performed. The test was positive in 24 patients (16%). The criteria for a positive test were only clinical in 3 patients, only ECG in 13 patients, and both in 8 patients. Inconclusive tests were observed in 27 patients (18%) and the test was negative in 99 patients (66%). There were no complications during the exercise test. At a median follow-up of 237 days (range 11-443 days), 11 clinical events were recorded (4 acute coronary syndromes and 7 revascularization procedures). Patients with a non-negative exercise test had a significantly shorter event-free survival (p < 0.005). CONCLUSIONS: The exercise test performed in selected patients coming to the ED with acute chest pain is safe and useful for further risk assessment.

Systemic chemotherapy in combination with pericardial window has better outcomes in malignant pericardial effusions.

OBJECTIVE: Our aim was to compare systemic chemotherapy (CT) with drainage and with pericardial window in the treatment of neoplastic pericarditis in patients with various malignancies included in the International Neoplastic Pericarditis Treatment study. METHODS: Patients treated with systemic CT alone (Group A), CT plus drainage (Group B), or CT plus pericardial window (Group C) were included. Treatment response was defined as complete response (ie, no more pericardial effusion or masses), partial response (ie, reduced total score, without requiring further treatments), stable disease (ie, unchanged total score), or progressive disease (ie, increased total score). Patients with partial or complete response were considered responders. RESULTS: This preliminary report included 175 patients (56.6% male) with a mean age of 54.21±14.26 years. Gender distribution, age, and follow-up duration was similar for all groups (P>.05). Prevalent cancer types were lung cancer (50.9%), breast cancer (14.9%), and lymphoma/leukemia (14.9%). Overall, 22.3%, 42.9%, and 34.9% of patients were in treatment group A, B, and C, respectively. There were 132 responders (75.3%). The rate of responders significantly differed between groups (P<.001); it was significantly higher in Group B than in Group A (P<.05) and in Group C than in Group B (P=.006). The significant factors affecting response were therapy (P=.002) and extent of effusion (P=.037). Kaplan-Meier analysis showed that patients in Group C had a significantly better survival rate than patients in the other groups (P=.001). CONCLUSIONS: Systemic CT plus pericardial window is a more effective treatment option compared with systemic CT alone and systemic CT plus drainage in patients with malignant effusions.

Incremental value of arterial stiffness over traditional risk factors in predicting subclinical cardiovascular remodeling in patients with moderate chronic renal failure.

Cardiovascular remodeling in chronic kidney disease (CKD) is responsible for the high mortality found in this condition. A total of 89 consecutive outpatients with stage III CKD and 52 patients with stage II CKD with similar degree of traditional atherosclerotic risk factors underwent routine echocardiographic and carotid Doppler examination, evaluating vascular and cardiac remodeling (intima-media thickness [IMT] and left ventricular mass index [LVMi]), and its relation with arterial stiffness, determined in the same examination, using an echo-tracking technique. Also the absolute values of LVMi and IMT were statistically similar between the 2 groups, their determinants were completely different, only in stage III the markers of renal impairment and arterial stiffness being independent predictors of cardiac and vascular modifications. We concluded that macroanatomical measurements do not fully describe cardiovascular remodeling in this setting. Arterial stiffness echo-tracking derived could add valuable information, being an easy-to-perform parameter during a routine examination.

Neoplastic pericardial disease in lung cancer: impact on outcomes of different treatment strategies. A multicenter study.

BACKGROUND: Local (intrapericardial) chemotherapy has been reported to be useful for the treatment of neoplastic pericardial disease, but it has never been compared to systemic chemotherapy, a combination of the two and simple pericardial drainage or sclerosis. METHODS: We analyzed the clinical and echocardiographic data of 119 patients, suffering of neoplastic pericarditis due to lung cancer (97 with non-small-cell), comparing the outcomes of four different treatment strategies (extended catheter drainage/sclerosis, systemic chemotherapy, local chemotherapy, and combined - local plus systemic - chemotherapy) at the last available follow-up or at the change of therapy after a treatment failure. The outcomes (based on semiquantitative evaluation of pericardial disease) were classified as complete, partial, no response and progressing disease. RESULTS: A complete response was achieved in 37/53 of patients with combined, in 12/22 with local, in 5/27 with systemic chemotherapy, respectively, and in 4/17 after drainage/sclerosis (p<0.001). Overall response was achieved in 51/53 with combined, 18/22 and 16/27 with local or systemic chemotherapy, respectively, and in 5/17 with drainage/sclerosis only (p<0.001). Survival was significantly better after combined chemotherapy (p<0.001) and 12/53 patients (23%) in this subgroup survived more than 1 year. The overall response rate was higher with intrapericardial cisplatinum than with other agents (98% vs 80%, χ(2)=7.69, p<0.01). CONCLUSIONS: Local chemotherapy, alone or with systemic chemotherapy, is effective in treating pericardial metastases from lung carcinoma, leading to a good control of pericardial effusion in 92% of cases, and to complete disappearance of effusion and masses in 65%. Combined therapy is significantly better than any other treatment. Pericardiocentesis and intrapericardial chemotherapy should be used whenever possible in lung cancer neoplastic pericardial disease, not only in case of tamponade.

Hydroxymethylglutaryl coenzyme-a reductase inhibitors delay the progression of rheumatic aortic valve stenosis a long-term echocardiographic study.

OBJECTIVES: This study sought to assess the effect of hydroxymethylglutaryl coenzyme-A reductase inhibitors (statins) on the progression of rheumatic aortic valve stenosis. BACKGROUND: The possible role of statins in slowing the progression of degenerative aortic valve stenosis (AS) is still debated. No information about the role of statin treatment in patients with rheumatic AS is available yet. METHODS: From our 1988 to 2008 echocardiographic database, we retrospectively identified all patients with rheumatic AS, with a baseline peak aortic velocity >or=1.5 m/s and at least 2 echocardiographic studies >or=2 years apart. Exclusion criteria were: severe aortic regurgitation, bicuspid aortic valve, and left ventricular ejection fraction <40%. RESULTS: The study population consisted of 164 patients (30 treated with statins) followed up for 8.5 +/- 4.2 years. Peak aortic velocity at baseline was not different in patients treated with statins versus untreated patients (2.3 +/- 0.8 m/s vs. 2.3 +/- 0.7 m/s, p = 0.84). There were no significant differences in sex, age, or follow-up duration between the 2 groups. Progression of AS severity was slower in patients receiving statins compared with untreated patients (annual change of peak aortic velocity: 0.05 +/- 0.07 m/s/year vs. 0.12 +/- 0.11 m/s/year, p = 0.001). An annual rate of peak velocity progression >or=0.1 m/s was found in 10% of statin-treated patients and in 49% of untreated patients (p < 0.0001). CONCLUSIONS: This is the first observation of a positive effect of statin treatment in reducing the progression of rheumatic AS. The underlying mechanisms remain to be clarified.

Use of the ejection fraction-velocity ratio in the hemodynamic assessment of aortic bioprosthetic valves.

BACKGROUND: A new echocardiographic severity index of aortic valve stenosis has been recently introduced: the ejection fraction-velocity ratio (EFVR), which is a simple ratio ejection fraction/4Vmax2. This nonflow corrected index demonstrated an excellent accuracy in quantifying the effective orifice area (EOA) in native aortic valves. There is no information about the reliability of EFVR in assessing aortic EOA in patients with bioprostheses. METHODS: In 141 consecutive patients with aortic bioprostheses (85 males, mean age 74 +/- 9 years), EOA was calculated by both continuity equation (CE) and EFVR. RESULTS: The correlation between CE and EFVR was highly significant (r = 0.88; P < 0.0001). The area under the receiver operating characteristic (ROC) curve was 0.97 (considering a positive case CE < 1.0 cm2, best cutoff of EFVR was <1.06). Using CE as gold standard and a cutoff of 1.0 for both indexes, EFVR showed good sensitivity (80%) and specificity (98%). Also in a subgroup of 46 patients with moderate or severe mitral regurgitation, the EFVR had a good diagnostic accuracy (sensitivity 89%, specificity 97%). In 91 patients with ejection fraction < or = 50%, the EFVR confirmed good sensitivity (79%) and specificity (97%). CONCLUSIONS: The EFVR, a simple and not time-consuming index, demonstrated a good diagnostic accuracy in assessing EOA also in patients with aortic bioprostheses. The presence of moderate to severe mitral regurgitation or left ventricular dysfunction does not reduce significantly the reliability of this new index. The EFVR can be taken into consideration in the clinical practice, at least when CE measurements are technically difficult.

Symptomatic aortic stenosis: does systemic hypertension play an additional role?

Hypertension and aortic stenosis represent 2 different models of left ventricular systolic overload. Previous studies have observed different remodeling patterns in these conditions. There is, however, little information about patients with coexisting aortic stenosis and hypertension. Echocardiography was performed in 193 consecutive patients with symptomatic aortic stenosis (113 males, 80 females; mean age, 68+/-9 years). The prevalence of systemic hypertension was assessed. Left ventricular mass index and relative wall thickness were measured from M-mode echocardiography. Four different left ventricular remodeling patterns were identified: normal remodeling, concentric remodeling, concentric hypertrophy, and eccentric hypertrophy. A history of hypertension was present in 62 patients (32%), whereas 131 patients were normotensive. No significant differences were found between hypertensive and normotensive patients with respect to age, male/female ratio, mean New York Heart Association class, distribution of symptoms, left ventricular systolic and diastolic function, and remodeling patterns. In hypertensive patients, however, symptoms were present with larger aortic valve areas and lower stroke work loss. Systemic hypertension is not rare in patients with symptomatic aortic stenosis (32% in our series). Left ventricular remodeling patterns are quite similar in hypertensive and normotensive aortic stenosis. Our results suggest that symptoms of aortic stenosis develop with larger valve area and lower stroke work loss in hypertensive patients, probably because of the additional overload due to hypertension itself. It could suggest that in patients with coexisting hypertension and aortic stenosis, hypertension should be treated more aggressively to delay the occurrence of symptoms, and these patients should be followed-up more closely.
