Abstract

The effectiveness and tolerability of nitrendipine (Bay e 5009) and atenolol in the treatment of mild or moderate arterial hypertension in monotherapy and in association were evaluated in a randomized double-blind study. The drugs were administered once daily at the dose of 20 mg for nitrendipine and 100 mg for atenolol. The trial consisted in two phases of monotherapy and of a combined regimen phase, whose sequence was randomly established; tablets were administered according to a double-dummy design. The results were evaluated according to the criteria of the Hypertension Detection and Follow-up Program Cooperative Group. 5/20 patients were considered "responders" after atenolol treatment, 4/20 after nitrendipine alone, and 14/20 after combined therapy. Side effects resulted mild in severity, and their incidence was lower during the association phase. The combination of atenolol and nitrendipine appears to improve the effectiveness and acceptability of both drugs.

Abstract

We report a case of moderate thrombocytopenia associated with purpura-like phenomenon (four ecchymoses) that occurred within 72 hours of clopidogrel initiation and resolved promptly with drug withdrawal. This 61-year-old patient previously experienced an adverse skin reaction to ticlopidine without changes in the platelet count and without any other laboratory abnormalities. Since the introduction of clopidogrel instead of ticlopidine for the prevention or treatment of several cardiovascular diseases, only 11 cases of thrombotic thrombocytopenic purpura among more than 3 million individuals treated with clopidogrel have been reported. Recently, a case of severe thrombocytopenia, without concomitant purpura-like lesions, during therapy with clopidogrel has been described. To our knowledge, this is the first case of thrombocytopenia associated with purpura-like lesions with no evidence of thrombotic thrombocytopenic purpura during clopidogrel treatment.

Abstract

To evaluate gender-related differences in left ventricular (LV) structure and function in aortic stenosis, LV biplane cineangiography, micromanometry and endomyocardial biopsies were carried out in 56 patients with aortic stenosis and normal coronary arteries. Patients were divided into males (M: n= θ35), and females (F: n= θ21). Sixteen normal subjects 8 M, 8 F) served as haemodynamic controls. Control biopsy data were obtained from six pre-transplantation donor hearts (3 M and 3 F). LV systolic function was evaluated by ejection fraction and its relationship to mean systolic circumferential wall stress, diastolic function by the time constant of LV pressure decay, peak filling rates and passive myocardial stiffness constant. Biopsy samples were evaluated for interstitial fibrosis, muscle fibre diameter and volume fraction of myofibrils. In a subset of 27 consecutive patients, biopsy samples were evaluated with a morphometric-morphological method, for total collagen volume fraction, endocardial fibrosis and the extension and thickness of orthogonal collagen fibres (cross-hatching). In patients with aortic stenosis, aortic valve area, aortic valve resistance and mean aortic pressure gradient were comparable in males and females, whereas end-systolic and end-diastolic volumes were larger in males than females. Ejection fraction was lower (56%) in males than females (64%) (P<0.05); 20 of 35 males and four of 21 females had depressed systolic contractility when assessed with regard to the relationship ejection fraction-mean systolic stress (P<0.01). Myocardial stiffness constant was higher in males than in females (P<0.0I). Nine of 14 males and two of 13 females had endocardial fibrosis (P<0.009), whereas increased cross-hatching (> 1.5 grade) was present in 11 males and four females with aortic stenosis (P<0.0I). An abnormal collagen architecture was present in 13114 males and 5113 females (V<0.002). In aortic stenosis, males have a depressed systolic function and abn

Abstract

Purpose: Although delayed-enhancement magnetic resonance imaging (DEMRI) is essential for diagnosis of cardiac sarcoidosis (CS), the test was not available when pacemaker was implamted. Recently, MR-conditional pacemaker has become avilable and we hypothesized that this device would be useful for diagnosis and management of CS. The aim of this study was to assess the diagnostic ability of MR-conditional pacemaker about CS in patients with advanced A-V nodal block (AAVB). Methods: Twenty-seven AAVB patients (14 men, 13 women; mean age, 69 ± 11 years) who were implanted MR-conditional pacemaker were studied. DEMRI was performed 6 weeks after implantation of permanent pacemaker. In patients with positive for DE, additional examinations like echocardiography, radioisotope imaging, biopsy, and coronary computed-tomography were performed due to confirm the diagnosis of CS and exclude coronary artery disease. Results: DE was observed in 12 patients (44 %). Out of 12 patients, 2 patients were excluded for having prior myocardial infarction. Seven of 10 (70 %) patients were diagnosed of CS by the consensus criteria. Compared with non-CS group, CS group had significantly lower age (61 ± 12 years vs. 72 ± 9 years p = 0.017). There was no significant difference about sex, angiotensin-converting enzyme, brain natriuretic peptide, and left ventricular ejection fraction between 2 groups. Six patients had started corticosteroid therapy and 5 patients (83%) recovered A-V nodal conduction. Conclusion: MR-conditional pacemaker was useful for diagnosis and management of patients with AAVB caused by CS. Figure Cardiac MRI in patient with AV block

Abstract

Background: LV contractility plays an important diagnostic and prognostic role in non-ischemic dilated cardiomyopathy (IDC). Systolic pressure/end-systolic volume relationship (SP/ESVi) is a useful method for evaluating LV myocardial contractility during stress echocardiography (SE). Coronary flow reserve (CFR) on left anterior descending (LAD) can be reduced in IDC. Aim: To assess the relationship between SP/ESVi and CFR on LAD in IDC patients Methods: We enrolled 134 IDC patients (98 men; 62 ± 12 years, mean value of ejection fraction: 34 ± 8%) and 38 age-sex matched normal subjects as control's group (29 men; 65 ± 11 years, mean value of ejection fraction: 61 ± 4%). All underwent dipyridamole SE (dip-SE 0.84 mg/kg in 6'). CFR was defined as the ratio between maximal vasodilation and rest peak diastolic flow velocity in LAD. SP/ESVI was defined as systolic cuff pressure/end-systolic volume index difference between rest-peak dip-SE. Results: SP/ESVi was 0.25 ± 0.74 mmHg/ml/m2 in IDC patients and 3.90 ± 2.67 mmHg/ml/m2 in controls. SP/ESVi was not related to ejection fraction at rest, while it was directly related to ejection fraction at peak dip-SE (r=.448, p<.001) and rest-stress difference in ejection fraction (r=.435, p<.001). CFR on LAD was abnormal (<2) in 66 (49%) IDC patients. SP/ESVi was directly related to CFR on LAD (r=.369, p=.001, Figure, red points) in IDC patients: LV contractile reserve affected increase in CFR, while in controls we did not find relationship between SP/ESVi and CFR (Figure, green points). Conclusions: In IDC with impaired LV systolic function CFR was directly related to LV myocardial contractility, while this relationship disappeared in normal subjects. Figure Figure

Abstract

Purpose: Transthoracic 3D echocardiography (3DE) allows an unparalleled opportunity for quantifying the dynamic changes of the tricuspid annulus (TA). Accordingly, our aims were: (I) to assess the determinants of TA size during cardiac cycle in healthy subjects; (II) to propose an approach and timing for TA sizing using 3DE. Methods: In 50 healthy volunteers (45±14 yrs, range 18-74, 27 males, with no risk factors, symptoms, signs or history of cardiovascular disease and on no medication), a full-volume dataset of the right ventricle (RV) containing the tricuspid valve (TV) was acquired (Vivid E9, GE Healthcare). TA diameters (septo-lateral, SL; antero-posterior, AP) and areas were measured on multiplanar images (Flexi-slice, EchoPac BT12, GE Healthcare) at 5 time points during the cardiac cycle: OS (onset of systole, at TV closure); MS (mid-systole); ES (end-systole); ED (onset of diastole); LD (late diastole, after the P wave). RV volumes and ejection fraction (EF) were analyzed with commercial software (4D RV analysis, TomTec, D). Results: Temporal resolution of the 3D datasets was 32±4 vps (range 24-53). TA areas were more closely correlated with RV volumes and body surface area (BSA) than with either SL or AP diameters. TA areas increased during systole from OS (3.9±0.6 cm2/m2) to ES (4.9±0.8 cm2/m2) and reached its largest area in LD (6.7±1.0 cm2/m2). All 5 TA areas were correlated with BSA (r range 0.57-0.62) and RV volumes (r ranges 0.53-0.60 for end-diastolic volume and 0.43-0.50 for end-systolic volume, p<0.0001 for all). Indexed TA areas were not related to either age or gender. With multivariable analysis, both RV end-diastolic volume and BSA determined TA areas during systole and early diastole, while TA area at LD and at OS were independently related with BSA only. Conclusions: In healthy subjects, the main determinants of TA size are RV volume and BSA. The largest TA area occurs at LD and is independently related with BSA only. Therefore, normative values should be based on TA areas measured at LD and indexed for BSA. However, the rapid change in TA areas occurring from LD to OS underscores the importance of adequate temporal resolution of 3DE data sets for reliable TA measurements.

Abstract

Aims To evaluate the impact of the COVID-19 pandemic on patient admissions to Italian cardiac care units (CCUs). Methods and Results We conducted a multicentre, observational, nationwide survey to collect data on admissions for acute myocardial infarction (AMI) at Italian CCUs throughout a 1 week period during the COVID-19 outbreak, compared with the equivalent week in 2019. We observed a 48.4% reduction in admissions for AMI compared with the equivalent week in 2019 (P < 0.001). The reduction was significant for both ST-segment elevation myocardial infarction [STEMI; 26.5%, 95% confidence interval (CI) 21.7–32.3; P = 0.009] and non-STEMI (NSTEMI; 65.1%, 95% CI 60.3–70.3; P < 0.001). Among STEMIs, the reduction was higher for women (41.2%; P = 0.011) than men (17.8%; P = 0.191). A similar reduction in AMI admissions was registered in North Italy (52.1%), Central Italy (59.3%), and South Italy (52.1%). The STEMI case fatality rate during the pandemic was substantially increased compared with 2019 [risk ratio (RR) = 3.3, 95% CI 1.7–6.6; P < 0.001]. A parallel increase in complications was also registered (RR = 1.8, 95% CI 1.1–2.8; P = 0.009). Conclusion Admissions for AMI were significantly reduced during the COVID-19 pandemic across Italy, with a parallel increase in fatality and complication rates. This constitutes a serious social issue, demanding attention by the scientific and healthcare communities and public regulatory agencies.

Abstract

Background: Cardiology divisions reshaped their activities during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to analyze the organization of echocardiographic laboratories and echocardiography practice during the second wave of the COVID-19 pandemic in Italy, and the expectations for the post-COVID era. Methods: We analyzed two different time periods: the month of November during the second wave of the COVID-19 pandemic (2020) and the identical month during 2019 (November 2019). Results: During the second wave of the COVID-19 pandemic, the hospital activity was partially reduced in 42 (60%) and wholly interrupted in 3 (4%) echocardiographic laboratories, whereas outpatient echocardiographic activity was partially reduced in 41 (59%) and completely interrupted in 7 (10%) laboratories. We observed an important change in the organization of activities in the echocardiography laboratory which reduced the operator-risk and improved self-protection of operators by using appropriate personal protection equipment. Operators wore FFP2 in 58 centers (83%) during trans-thoracic echocardiography (TTE), in 65 centers (93%) during transesophageal echocardiography (TEE) and 63 centers (90%) during stress echocardiography. The second wave caused a significant reduction in number of echocardiographic exams, compared to November 2019 (from 513 ± 539 to 341 ± 299 exams per center, −34%, p &lt, 0.001). On average, there was a significant increase in the outpatient waiting list for elective echocardiographic exams (from 32.0 ± 28.1 to 45.5 ± 44.9 days, +41%, p &lt, 0.001), with a reduction of in-hospital waiting list (2.9 ± 2.4 to 2.4 ± 2.0 days, −17%, p &lt, 0.001). We observed a large diffusion of point-of-care cardiac ultrasound (88%), with a significant increase of lung ultrasound usage in 30 centers (43%) during 2019, extended to all centers in 2020. Carbon dioxide production by examination is an indicator of the environmental impact of technology (100-fold less with echocardiography compared to other cardiac imaging techniques). It was ignored in 2019 by 100% of centers, and currently it is considered potentially crucial for decision-making in cardiac imaging by 65 centers (93%). Conclusions: In one year, major changes occurred in echocardiography practice and culture. The examination structure changed with extensive usage of point-of-care cardiac ultrasound and with lung ultrasound embedded by default in the TTE examination, as well as the COVID-19 testing.

Abstract

An enlarged left atrial volume index (LAVI) at rest mirrors increased LA pressure and/or impairment of LA function. A cardiovascular stress may acutely modify left atrial volume (LAV) within minutes. Aim of this study was to assess the feasibility and functional correlates of LAV-stress echocardiography (SE) Out of 514 subjects referred to 10 quality-controlled labs, LAV-SE was completed in 490 (359 male, age 67 ± 12years) with suspected or known chronic coronary syndromes (n = 462) or asymptomatic controls (n = 28). The utilized stress was exercise in 177, vasodilator in 167, dobutamine in 146. LAV was measured with the biplane disk summation method. SE was performed with the ABCDE protocol. The intra-observer and inter-observer LAV variability were 5% and 8%, respectively. ∆-LAVI changes (stress-rest) were negatively correlated with resting LAVI (r = −0.271, p < 0.001) and heart rate reserve (r = -.239, p < 0.001). LAV-dilators were defined as those with stress-rest increase ≥ 6.8ml/m2, a cutoff derived from a calculated reference change value above the biological, analytical and observer variability of LAVI. LAV dilation occurred in 56 patients (11%), more frequently with exercise (16%) and dipyridamole (13%) compared to dobutamine (4%, p < 0.01). At multivariable logistic regression analysis, B-lines ≥ 2 (OR: 2.586, 95% CI = 1.1293–5.169, p = 0.007) and abnormal contractile reserve (OR: 2.207, 95% CI = 1.111–4.386, p = 0.024) were associated with LAV dilation. In conclusion, LAV-SE is feasible with high success rate and low variability in patients with chronic coronary syndromes. LAV dilation is more likely with reduced left ventricular contractile reserve and pulmonary congestion.

Abstract

Dual antiplatelet therapy (DAPT) is a cornerstone of treatment for patients with acute coronary syndromes (ACS). Mounting evidences have opened the debate about the optimal DAPT duration. Considering the ACS-pathophysiology, the most recent guidelines recommend DAPT in all ACS patients for at least 12 months unless there are contraindications such as excessive risk of bleeding. Thus, it can be considered acceptable earlier discontinuation if the risk of morbidity from bleeding outweighs the anticipated benefit. On the other hand, several studies have clearly indicated that a significant burden of platelet related-events, such as stroke and new ACS might occur after this period, suggesting that potential benefits might derive by prolonging DAPT beyond 12 months (Long DAPT). Indeed, although current guidelines give some indications about patients eligible for Long DAPT, they do not embrace several real-life clinical scenarios. Thus, in such scenarios, how to decide whether a patient is eligible for Long DAPT or not might be still challenging for clinicians. This position paper presents and discusses various “real-life” clinical scenarios in ACS patients, in order to propose several possible recommendations to overcome guidelines potential limitations.

Abstract

BACKGROUND: The factors that influence infarct expansion early after myocardial infarction have been identified; however, there is less information about late-phase left ventricular enlargement. This study was designed to identify the clinical, haemodynamic, echocardiographic, and radionuclide angiographic criteria that predict the progress of left ventricular dilation after discharge for a first-anterior myocardial infarction. METHODS: Sixty-seven patients with first Q-wave acute anterior myocardial infarction not treated with thrombolytic agents underwent baseline echocardiographic, haemodynamic, and radionuclide angiographic evaluation 4-7 days after the onset of symptoms. The echocardiographic and radionuclide evaluations were repeated after 1 year in the 55 patients who completed the follow-up. By multivariate stepwise linear regression analysis, left ventricular end-diastolic volume after 1 year and change from baseline were modelled as a function of baseline left ventricular end-diastolic volume and other potential predictors. RESULTS: A model including left ventricular end-diastolic pressure, global wall motion score, baseline left ventricular end-diastolic volume, and a Thrombolysis in Myocardial Infarction (TIMI) score of 0-1 was able to predict 84% of the left ventricular end-diastolic volume at the follow-up; a TIMI score of 0-1, the transverse end-diastolic diameter, global wall motion score, and the number of coronary vessels with 70% stenosis accounted for 81% of the variation in left ventricular end-diastolic volume from baseline, while the transverse end-diastolic diameter was inversely related to this parameter. CONCLUSIONS: The results of this study demonstrate that after an anterior myocardial infarction, the patency of the infarct-related artery is the major determinant of late left ventricular dilation, while left ventricular end-diastolic pressure influences early left ventricular dilation and baseline end-diastolic volume. Therefore, to improve left ventricular remodelling, it appears necessary to increase the patency of the infarct-related artery and improve the diastolic loading of the left ventricle at an early stage in the infarction. The inverse relationship between baseline left ventricular transverse diameter and the change in left ventricular volume after discharge indicates that the higher the baseline left ventricular volume, the less it changed during the follow-up. The global wall motion score appears to be a non-invasive parameter that is useful for identifying patients with a high risk of progressive left ventricular dilation.

Abstract

Objectives. This study was designed to increase asynchrony with sequential atrioventricular (AV) pacing and to study its effects on left ventricular isovolumetric relaxation, rapid filling and stiffness. Background. Left ventricular nonuniformity is a major determinant of diastolic function. Methods. Thirteen patients with coronary artery disease were studied by simultaneous equilibrium radionuclide angiography and cardiac catheterization during atrial and AV pacing. Ejection fraction and peak filling rate were measured by radionuclide angiography. Regional analysis was obtained by analyzing time-activity curves of four left ventricular sectors; systolic and diastolic asynchrony were evaluated as the coefficient of variation of time to end-systole and, respectively, time to peak filling rate in the four sectors. Cardiac index and left ventricular pressure were measured with high fidelity catheters at cardiac catheterization. The time constant of isovolumetric relaxation was derived from left ventricular pressure. Pressure-volume loops were assembled and constants of chamber stiffness were computed. Results. Atrioventricular pacing led to a decrease in cardiac index (3.7 ± 0.9 to 3.3 ± 0.8 liters/min per m2, p = 0.01) and peak filling rate (352 ± 125 to 287 ± 141 ml/s, p = 0.03; 2.4 ± 0.8 to 2.0 ± 0.8 end-diastolic counts/s, p = 0.02; 4 ± 1.3 to 3.2 ± 1.0 stroke counts/s, p = 0.008). The time constant of isovolumetric relaxation increased (57 ± 10 to 64 ± 12 ms, p = 0.04) and the global diastolic pressure-volume relation shifted upward. Conclusions. Atrioventricular pacing induces left ventricular asynchrony, which is associated with a slower rate of isovolumetric relaxation. The isovolumetric relaxation lasts after the filling phase has begun, thereby reducing the rate of rapid filling.

Abstract

B-type natriuretic peptide (BNP) is a diagnostic and prognostic marker in heart failure (CHF) patients. Aim. To assess the relation between BNP, diastolic function and exercise capacity in CHF patients. Methods. Fifty CHF patients underwent cardiopulmonary exercise testing. BNP levels were determined at baseline and at peak exercise. Patients were divided in two groups: with lower (/=14 ml/kg/min) peak oxygen consumption (VO(2)). Results. Seventeen patients with lower peak VO(2) showed larger incidence of restrictive pattern of the transmitral flow (7/17 vs 4/33, p =0.036). E/Ea ratio was inversely related with peak VO(2) (r =-0.419, p =0.004) and directly related with BNP levels at baseline (r =0.449, p =0.001) and at peak exercise (r =0.475, p =0.001). LV ejection fraction was similar in the two groups. Independent predictors of exercise tolerance were E/Ea ratio (p =0.003), lg BNP at baseline (p =0.034) and increase in lg BNP during exercise (p =0.038). Conclusions. In CHF patients, E/Ea ratio is a predictor of exercise tolerance and is related with BNP level at rest and at peak exercise.

Abstract

This study assesses whether administration of recombinant tissue-type plasminogen activator (rt-PA) up to 8 hours after onset of symptoms of acute myocardial infarction (AMI) may result in a significant improvement in left ventricular function. Sixty patients were classified into 3 groups: group A (n = 21) received rt-PA within 4 hours from symptom onset; the remaining 39 patients, admitted between 4 and 8 hours, were randomized into 2 groups--group B (n = 19) received rt-PA, and group C (n = 21) was treated with conventional therapy. Coronary and left ventricular angiograms were recorded 8 to 10 days after rt-PA administration. The patency rate of the infarct-related artery was 76% in group A, and 63 and 35% in group B and C, respectively. The Thrombolysis in Myocardial Infarction trial perfusion grade was higher in group A and B than in group C (A vs C: p less than 0.005; B vs C: p less than 0.01). Left ventricular ejection fraction was significantly higher in group A (60.2 +/- 10%) and B (54.7 +/- 12%) compared with group C (44.2 +/- 12%) (A vs C: p less than 0.01; B vs C: p less than 0.05). Regional wall motion of the entire ischemic zone was better in group A and B than in group C (A vs C: p less than 0.001; B vs C: p less than 0.01). In contrast, the kinesis of the central ischemic zone was significantly better in group A than in both group B and C (A vs B: p less than 0.05; A vs C: p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract

To evaluate the effects of late thrombolysis on left ventricular volume and function in acute myocardial infarction, two-dimensional echocardiography and radionuclide angiography were performed before discharge and after 1 year of follow-up study in 34 patients with acute anterior myocardial infarction. Of these, 10 admitted to the coronary care unit within 4 h from the onset of symptoms were treated with recombinant tissue-type plasminogen activator (rt-PA) (Group A) and 24 admitted between 4 and 8 h after onset were randomly assigned to receive either rt-PA (Group B, n = 12) or conventional therapy (Group C, n = 12). Seven to 10 days after admission, all patients underwent cardiac catheterization and coronary angiography. Patency of the infarct-related vessel was 70% in Group A, 66% in Group B and 33% in Group C and the average Thrombolysis in Myocardial Infarction (TIMI) coronary perfusion grade was 1.9 +/- 0.8 for Group A, 1.6 +/- 1.0 for Group B and 0.84 +/- 0.95 for Group C (Group A versus Group C p less than 0.01; Group B versus Group C p less than 0.05). At predischarge evaluation, mean left ventricular end-systolic and end-diastolic volumes were higher in Group C than in Group B (p less than 0.001 and 0.05, respectively) and Group A (p less than 0.005 for both); mean left ventricular ejection fraction at rest was lower in Group C than in Group B and Group A (p less than 0.05 for both). At 1 year follow-up study, end-systolic and end-diastolic volumes remained higher in Group C than in Group B (p less than 0.05 for both) and Group A (p less than 0.005 for end-systolic volume and p less than 0.001 for end-diastolic volume); ejection fraction at rest was lower in Group C than in Groups A and B (p less than 0.05 for both); during exercise, it increased more in Group A than in Group C (p less than 0.01). Comparison of data obtained before discharge and at the 1 year follow-up study revealed a significant differences in end-systolic volume (p less than 0.05) in Group C patients and in end-diastolic volume in patients in Groups B (p less than 0.05) and C (p less than 0.001). The beneficial effect of late thrombolysis with rt-PA may be related to a reduction in myocardial expansion and thus to a favorable influence on postinfarction left ventricular remodeling.

Abstract

Background. Abnormal blood-pressure response during exercise occurs in about one third of patients with hypertrophic cardiomyopathy (HCM), and it has been associated with a high risk of sudden cardiac death. We assessed the hemodynamics of exercise in HCM patients with abnormal blood-pressure response by using ambulatory radionuclide monitoring (VEST) of left-ventricular (LV) function, and exercise tolerance by oxygen consumption. Methods. Twenty-two HCM patients uderwent treadmill exercise during VEST monitoring. A cardiopulmonary exercise test was performed a few days after. The VEST data were averaged for I minute. Stroke volume, cardiac output, and systemic vascular resistance were expressed as percent of baseline. Exercise tolerance was assessed as maximal oxygen consumption. Results. In eight HCM patients (36%) with an abnormal blood-pressure response, end-systolic volume increased more (52% +/- 21% vs 31% +/- 28%, P = .012), and the ejection fraction (-31% +/- 17% vs -14% +/- 22%, P = .029) and stroke volume (-21% +/- 21% vs 3% +/- 28%, P = .026) fell more, than in patients with normal response. Cardiac output increased less in the former patients (49% +/- 44% vs 94% +/- 44%, P = .012). Systemic vascular resistance decreased similarly, irrespective of blood-pressure response (-28% +/- 26% vs -34% +/- 26%, P = N.S.). Percent of maximal predicted oxygen consumption was lower in HCM patients with an abnormal blood-pressure response (63% +/- 11% vs 78% +/- 15%, P = .025). Conclusions. In HCM patients, abnormal blood-pressure response was associated with exercise-induced LV systolic dysfunction and impairment in oxygen consumption. This may cause hemodynamic instability, associated with a high risk of sudden cardiac death.

Abstract

1 ABSTRACT: Background. Hypertrophic cardiomyopathy (HCM) is characterized by asymmetric LV hypertrophy (LVH) and impairment in diastolic function. We assess the relationship between LVH and invasive indexes of diastolic function. Methods. 21 HCM patients underwent cardiac catheterization to assess pulmonary capillary wedge pressure, LV end-diastolic pressure (measured by microtip catheters), and LV volumes (calculated by simultaneous radionuclide angiography). We calculated from LV pressure the time constant of isovolumetric relaxation (τ, variable asymptote method, ms), and from LV pressure and volume the constant of chamber stiffness (k, ml -1 ). LVH was assessed by different indexes: maximal wall thickness, number of hypertrophied LV segments, LVH index, and Wigle's score. Results. Wigle's score was directly related to pulmonary capillary Wedge pressure (r=0.436, p=0.048), peak V wave of pulmonary capillary wedge pressure (r=0.503, p=0.024), LV end-dias- tolic pressure (r=0.643, p=0.002) and k (r=0.564, p=0.015). HCM patients were divided into 2 groups according to Wigle's score: 10 with mild or moderate LVH (< 8), and 11 with severe LVH (≥ 8). HCM patients with severe LVH showed a higher pulmonary capillary Wedge pressure (15.1±7.2 vs 9.5±2.4, p=0.033), peak V wave of pulmonary capillary wedge pressure (20.7±4.6 vs 14.6±4.9, p=0.011), LV end-diastolic pressure (23.9±10.9 vs 10.6±2.5, p=0.002), k (0.0465±0.032 vs 0.015±0.007, p=0.022) and LV outflow tract gradient (72±36 mmHg vs 29±30 mmHg, p=0.01). τ was similar in the two groups. Other indexes of LVH were not related to dias- tolic function. Conclusions. Wigle's score is the only index of LVH that relates to invasive indices of diastolic function.
