We studied 34 consecutive patients with primary aldosteronism and 34 with essential hypertension individually matched for age, gender, race, body mass index, blood pressure values, and duration of hypertension. The groups were similar in age, body mass index, blood pressure, and duration of hypertension. However, lower serum potassium levels (3.5\u00b10.6 versus 4.1\u00b10.2 mmol\/L,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.0001) and plasma renin activity (0.53\u00b10.45 versus 1.82\u00b11.59 ng Ang I\u00b7mL\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00b7h\n                    <jats:sup>\u22121<\/jats:sup>\n                    ,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.0001) and higher plasma aldosterone levels (1107\u00b1774 versus 206\u00b199 pmol\/L,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.0001), left ventricular wall thickness, and left ventricular mass index (112\u00b14.7 versus 98\u00b13.7 g\/m\n                    <jats:sup>2<\/jats:sup>\n                    ,\n                    <jats:italic>P<\/jats:italic>\n                    =.029) were found in patients with primary aldosteronism compared with those with essential hypertension. Similarly, the PQ interval was longer (173\u00b120 versus 141\u00b114 milliseconds,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.001) in primary aldosteronism than in essential hypertension patients. Significantly more primary aldosteronism than essential hypertension patients had left ventricular hypertrophy or left ventricular concentric remodeling (50% versus 15%, \u03c7\n                    <jats:sup>2<\/jats:sup>\n                    =11.97,\n                    <jats:italic>P<\/jats:italic>\n                    =.007). Both the E wave flow velocity integral (1063\u00b165 versus 1323\u00b178,\n                    <jats:italic>P<\/jats:italic>\n                    =.013) and the E\/A integral ratio (0.91\u00b10.05 versus 1.25\u00b10.08,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.001) were lower, and atrial contribution to left ventricular filling was higher (53.3\u00b11.5% versus 45.5\u00b11.3%,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;.001) in patients with primary aldosteronism compared with essential hypertension patients. After 1 year of follow-up, highly significant decreases of left ventricular wall thickness and mass were observed in patients treated with surgical excision of an aldosterone-producing tumor, but not in those treated with medical therapy. Thus, in patients with primary aldosteronism, the excess aldosterone with suppression of the renin-angiotensin system is associated with both increased left ventricular mass and significant changes of left ventricular diastolic filling. The former changes appear to be reversible on removal of the cause of excessive aldosterone production.\n                  <\/jats:p>","DOI":"10.1161\/01.hyp.27.5.1039","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T20:53:46Z","timestamp":1339448026000},"page":"1039-1045","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":261,"title":["Changes in Left Ventricular Anatomy and Function in Hypertension and Primary Aldosteronism"],"prefix":"10.1161","volume":"27","author":[{"given":"Gian Paolo","family":"Rossi","sequence":"first","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfredo","family":"Sacchetto","sequence":"additional","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pieralberto","family":"Visentin","sequence":"additional","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Canali","sequence":"additional","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gian Rocco","family":"Graniero","sequence":"additional","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Palatini","sequence":"additional","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Achille C.","family":"Pessina","sequence":"additional","affiliation":[{"name":"From the Department of Clinical and Experimental Medicine, University of Padua Medical School and Azienda Ospedaliera di Padova (Italy)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199005313222203"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-114-5-345"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.90.6.7994801"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.83.1.1824620"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/res.68.4.2009615"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/res.62.4.3280155"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/res.67.6.1700933"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.83.6.1828192"},{"key":"e_1_3_2_9_2","doi-asserted-by":"crossref","unstructured":"Weber KT Brilla CG.
